RE: Varient Model on Fcc.
It private branding of equipment A to become B is the issue, then there is no issue. The FCC ID belongs to the manufacturer of A and no change of the Grant is required. A new Grant would be required if the equipment were manufacturered by someone else.

Tommy, I'm not exactly sure what you're asking. If you're asking if a Product which is labeled as Class A can be relabeled as a Class B product because they look the same, the answer is no. The product must be properly retested to assure its compliance with the Class B limits and then you must have a test report approved by the FCC. I have little doubt that if the two really were the same they would be labeled differently. Secondly, the FCC ID is a means of identifying the manufacturer. Therefore, unless your company is the holder of the FCC ID in question, I suggest you ask the printer manufacturer the question you're posing to the group.

RE: general product classification
CENELE lists the scope, or part of it, on its site http://www.cenelec.org/ For example, here is what they say about EN 55022: This standard applies to ITE as defined in 3.1. Procedures are given for the measurement of the levels of spurious signals generated by the lTE and limits are specified for the frequency range 9 kHz to 400 GHz for both Class A and Class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this standard is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results.

RE: Keep off the grass: RF emissions!
If it is an intentional radiator and operates above 9 kHz, it is considered to be a transmitter. If so, it is considered to be an inductive loop short range device in Europe and subject to EN 300330-1 and -2 for radio emissions and EN 301489-1 and -3 for spurious emissions and immunity. FCC Part 15 rules applies in the US and Industry Canada RSS-210 applies in Canada. However, one might be able to construct a reasonable argument that the device is not an intentional radiator because the signal is inductively coupled to the mower and that any emissions outside the boundary is unintentional. The problem with the argument is that the loop and mower are not physically attached or in proximity all of the time.

Hello everybody! A friend of mine, overthinking of the breadth of my knowledge, is asking me for some advise about the applicable standards to a rather unusual piece of equipment. It is a auto mower intended to be programmed by the user to cut within a given garden area. It makes use of a boundary loop wire to exchange information (by means of RF TX-RX) about the actual position and the cutting area. It is provided also with a docking station where it goes automatically to recharge its battery. Now the questions. Is there any applicable product standard dealing with EMC and safety of that kind of devices? Do you think it is to be handled as an intentional RF transmitter, similarly to an ISM? Let's consider it is not an intentional transmitter, as the emission depends on the broadness of the reference loop, does it make sense to do measurement at three or ten meters? Do you think immunity as well can be anlysed regardless the actual installation?

National EMF Exposure Regulations
This message is addressed to members affected by national regulations for EMF exposure of workers and the general public, especially in Europe. I am attempting to learn at an early stage when national regulations are being developed or revised, but I am having great difficulty in finding persons, publications or web sites that have that information. Specifically, I am creating a list of knowledgeable persons (agency contacts, consultants, and other persons), agencies (government and private), web sites, professional organizations, and publications. I am aware of the following developments: * Italy: three decrees are to be written to support the new law * Germany: BGV B11 is a worker exposure regulation that is now in effect and equipment is being tested by the BG lab * Germany: the 26th Ordinance covering public exposure is going to be revised. The SSK has provided the Ministry of Environment with recommendations I would like to hear from others on how they manage this process and if they know of any other developments.

RE: Electronic Surveillance Systems
Inductive applications are NOT to be used in the 10.2-11 MHz band per CEPT Recommendation 70-03 (short range devices). The allowed bands in this frequency range are 7.4-8.8 MHz and 13.553-13.567 MHz. In fact, the frequency you mention is not listed for use by any type of short range device.

The EMF Project is currently reviewing research results and conducting risk assessments of exposure to static and extremely low frequency (ELF) electric and magnetic fields. WHO plans to conduct an evaluation of all health effects from ELF field exposure in 2002-3. Whenever electricity is conducted through transmission lines, distribution lines or is used in appliances, both electric and magnetic fields exist close to the lines or appliances. The power frequency used is 50 or 60 Hz. Use of electric power has become part of everyday life. However, questions have been raised as to whether these and other ELF fields are carcinogenic. The International Agency for Research on Cancer (IARC) - a specialized cancer research agency of WHO - has recently concluded the first step in WHO's health risk assessment process by classifying ELF fields with respect to the strength-of-the-evidence that they could cause cancer in humans. http://monographs.iarc.fr/. etc etc You can find a copy of this fact sheet on the WHO EMF Project Website at: http://www.who.int/peh-emf/publications/facts_press/efact/efs263.html And the French Version at: http://www.who.int/peh-emf/publications/facts_press/FS263%20French.htm 263 ELF and Cancer French.htm 263 ELF and Cancer.htm Kind regards Sarah *** Sarah Bullock Secretary, Radiation Group Occupational and Environmental Health World Health Organization 20 Avenue Appia CH-1211 Geneva 27 Switzerland Tel +41 22 791 40 76 Fax +41 22 791 41 23 Email bullo...@who.int *** -- End of Forwarded Message 263 ELF and Cancer.htm Description: Binary data
General Product Safety Directive
The following message was distributed by ETSI. A meeting was held on 12th September 2001 between CEN, CENELEC, ETSI and the European Commission with regard to identifying European standards to be used in the framework of the General Product Safety Directive (GPSD) that is expected to be adopted later this year. (See attachment) The steps I outlined and accepted at the meeting were: 1) Identify standards under the LVD/RTTED/etc that would also be suitable for listing under the GPSD 2) Identify any existing safety standards other than 1) that would be suitable for listing under the GPSD 3) Identify the need for any new standards. The Chairman of TC Safety who was present at the meeting believes that for 1) and 2) the answer is 'none' and so the question to the ETSI membership is whether you think that there are any ETSI standards needed in category 3). Note that the GPSD applies to ALL products, whether electrical or not. Therefore, earpieces and other accessories for mobile 'phones would be covered (as they are by the existing GPSD today). Similarly, this Directive would likely cover the range of self-powered Bluetooth devices. Please could you send any input that you may have to this exploder list before 31st October 2001.

RE: Generic vs Product Specific Specifications for European Direc tives
Trevor, the new product specification must be applied by the date of withdrawal (DOW) that can be found in the new standard. The date is also posted on the CENELEC and ETSI web site - I don't know about CEN. However, keep in mind that the new product specification is not harmonized under most directives (this does not apply to the LVD, for example) until its reference is published in the OJ.

RE: ESD Immunity Testing
You raise a good point John. ESD testing to find hard failures (service call required) does not require a statistical process. A few well placed high voltage zaps can find that type of failure. However, recoverable (operator intervention) or self-recoverable errors are by far the most likely result on an ESD event. Consider your PC that occasionally halts or displays the blue screen of death. What caused it? Can an ESD event be ruled out? Probably not considering that one can expect to encounter 77 ESD events per thousand hours at or above 8 kV in an environment with no ESD controls.

ESD Immunity Testing
Since my last posting on trying to find an ESD expert, I have had to become that expert. After reading the ANSI ESD standard and its references, it is clear that ESD experts are mostly in agreement on how to correctly perform ESD immunity testing. It is also clear test methods in the EN/IEC specifications do not follow that advice. ESD testing is a statistical process, so the test methods and the analysis of the results must be based upon statistics. There are three basic causes. 1) The distribution of ESD events in the operating environment has a non-uniform distribution where the number of expected events per hour is inversely proportional to approximately the square of the voltage. This implies in testing that the number of applied zaps in testing and their levels should also follow this distribution. 2) Digital devices are state machines and some states may be less immune to ESD than other states. This implies that each state should be tested. However, most digital devices have a huge number of states and they change very quickly; therefore, the only way to ensure that even most of the states have been evaluated is to apply a very large number of zap. 3) There may be a probability distribution for the locations on the machine where an ESD discharge is likely to occur. That is, it is not always equally likely that a person or an object will come in contact with any given point on any given surface. Statistics can be used to determine the voltage levels that should be applied and the quantity required at each level in order to provide a specified confidence level that a machine will have no more than a specified number of errors per unit time. However, the number of zaps required is very high, usually in the order of one to ten thousand. The drawback, of course, it that the testing can be time consuming. However, applying in the order of one hundred zaps to a machine according to the EN/IEC specifications will provide such a very, very low confidence level that one cannot reasonably predict the expected error rate in the field. Worst, the results are not repeatable since some states may be tested during one test session and others may be tested during another session. The only predictable case where this might not occur would be with a machine with an ESD robustness level for all states that are far above the actual test levels. So here is my question to those of you involved in the EN/IEC standards - why have these statistical test processes not been acknowledged in the standards?

RE: 134kHz transmitter in the U.K.
Bob brings up a good point. The band edge is at 135 kHz and the modulation sidebands must be down to the specified level at that frequency which limits the modulation methods. ETSI is considering a revision that will allow a spectrum mask with some of the modulation components falling outside the band.

RE: 134kHz transmitter in the U.K.
Bob, each EEA member state has implemented the RTTE into national law. Those national laws apply to your product. However, you may rely upon following the requirements of the actual RTTE Directive. For your product, the applicable radio standards are EN 300 330-1 and EN300330-2. The latter is published in the OJ. Note that the RTTE directive requires compliance with health and safety which are code words for human exposure to electromagnetic fields. Council Recommendation 1999/519/EC applies for public limits and ICNIRP 1998 guidelines apply for worker limits. CENELEC EMF standards have been approved at the national level but not yet published. They are prEN50357 and prEN50364. Note that the frequency is not harmonized, so the appropriate procedures of the RTTE must be followed.

Bob, the -1 standard will not be published in the OJ since it is considered to be a reference standard similar to the same status as the EN 61000-4 series.

Indeed, it refers to compliance with all directives relevant to the product, so a teddy bear will be CE marked if it meets the requirements of the toy directive and all relevant safety directives. Pressure vessels will have to meet the requirements of the pressure directive and so on, and if any product crosses boundaries, it has to meet all the applicable directives. However, the CE mark is a declaration of conformity and you can self certify. This means I can disappear into my garage for a few weeks and emerge with a CE marked product - and it would be perfectly legal - as long as the declaration is true i.e. I have done what needs to be done to prove compliance, and one way to do this would be to test to applicable harmonised standards. Validity of self certification may change in due course but at the moment, that is how it is. I like Chris Maxwell's spin on the meaning of CE, and it would be true if every firm made a distinction between the compliance engineer and the designer. In all the companies I have worked for - we do it all i.e. the designer designs to spec, takes the product through type approval tests, then through precompliance and then through full compliance. So the electronics designers are responsible for meeting all the applicable directives (EMC, electrical safety) and functional type approval and they do so by product proving and EMC testing the product themselves - to the applicable standard. They are also responsible for the technical documentation for the electrical aspects of the product. The mechanical engineers and hydraulics engineers do likewise and when it's all done, the fall guy (engineering director) puts his signature on the declaration of conformity. What this means is that if the declaration should subsequently be proven false, he is the one who goes to the gallows. Wait a minute! I used to think everyone worked that way, but I get the feeling I may be doing too much! That does it! I am off to see the payroll people soon after sending this e-mail and hopefully will emerge with a CE marked cheque - or CE marked letter of dismissal!!

ESD Testing
From your actual experiences or knowledge, which of the following ESD tests is more severe (i.e., more likely to cause disruption of operation) given that the same pre-discharge voltages are used: * Air discharge using generator and procedures of IEC 801-2:1984 (the old standard), or * Air discharge using generator and procedures of IEC 61000-4-2:1995 + A1:1998 (the current standard) The reason for asking is that we have evidence from past experiences with the older standard what level we should test to for quality purposes, and now we are attempting to set the levels per the new standard. Note that this is for internal quality purposes and not legal compliance. And, before someone mentions it, we will also be testing with contact discharge, but that is not the question at hand.

RE: Noise from flourescent light ballasts?
We have experienced noise from variable frequency motor controllers used in air conditioning systems. There may also be some of these controllers in your factory controlling conveyer belts and other machinery. Richard Woods -- From: Chris Maxwell [SMTP:chris.maxw...@nettest.com] Sent: Thursday, September 06, 2001 11:38 AM To: EMC-PSTC Internet Forum Subject: Noise from flourescent light ballasts? Hi all, We have personally experienced an interesting phenomenon. We build a certain circuit that detects a 20Khz tone. This circuit is housed in a product that has an EMI spray coated case. One of our engineers noticed that our techs on the manufacturing floor were having a difficult time setting up units on the floor. The tone detect circuit kept getting set off for apparantly no reason. However, back in the engineering lab, we have no problems. So we did a little experiment. We took a unit out to the manufacturing floor and opened its case (which is how they work on them in manufacturing). We held it up near the lights. The tone detect circuit went crazy. We put the unit down on the bench. No problem. But, if you leave it opened up on the bench and hold your hand over the board, the circuit goes off again. When we close up the case work, all of these problems go away. So, our obvious solution is to make a modified casework with tweaker holes so that manufacturing personnel can tweak the amplifier pots with the casework closed. But I'm still curious. What's causing the interference? I was wondering if flourescent light ballasts could be giving off an emission in the KHz range. (Maybe that's why holding it to the lights sets it off.) But what about the hand waving? If I assume the ballasts are giving off emissions, can I also assume that the human body can change the local field pattern? Am I barking up the wrong tree? Maybe its the LAN cables in the ceiling? Anybody else have a similar experience or some insight into this?

RE: Standard for EM Immunity for cardiac pacemakers?
Peter, both CENELEC and IEC are developing pacemaker EMC standards. The only published document is EN 50061/A1 which has not been published in the OJ. That standard will be replaced by EN45502-X.

RE: Electroshock exercising devices ...
TENS units (Transcutaneous electronic nerve stimulation) are widely used to treat pain. Muscle stimulators work on the same principle. Nerves will activate (e.g., muscle contraction) with an e-field of 1.2 V/m. Here is a spec for a typical TENS: Pulse amplitude: 0-80 ma, adjustable Pulse freq.: 2-150 Hz, adjustable Pulse width: 50-250 usec, adjustable Maximum open circuit voltage: 100V Maximum charge: 16 mC/pulse TENS are available only with a prescription and the user manual says to use the device only as directed by your doctor. The devices are battery operated, transformer coupled and impedance limited, so they are considered to be safe even under a fault condition. One safety note - it should not be used where a current path would cross the heart since the pulses might be disrupt the heart beat. My guess is that the exercisers operate on a lower power level in order to get under the FDA regulations - just enough power to stimulate the nerves. Approvals? What approvals?

RE: Testing for the EMC directive
John, thanks for that update. Now I have to wonder if I am testing our ITE correctly. We have an ITE that has a thermostat and heater for outdoor use. We have been testing the heating circuit to the click requirements of EN 55014-1. However, it would appear that one could reverse the CENELEC reasoning and say that primary function determines the standard to be used - in this case it would be EN55022 - and the clicks from the heating circuit would not be evaluated. Strange. Richard Woods -- From: John Woodgate [SMTP:j...@jmwa.demon.co.uk] Sent: Thursday, August 16, 2001 4:41 PM To: emc-p...@majordomo.ieee.org Subject: Re: Testing for the EMC directive I read in !emc-pstc that wo...@sensormatic.com wrote (in EDFA411E5E4AD2 118D6F00A0C99E4BAC0386B0B5@FLBOCEXU02) about 'Testing for the EMC directive', on Thu, 16 Aug 2001: It is confusing. Yes, the scope of EN 55014-2 does say it applies to equipment even if it contains electronic circuits. But the scope of EN 55014-1 says that the present standard applies unless the rf energy is intentionally generated. That means 'intentionally to USE the r.f.'. In that case, EN55011 applies, not EN55022. The scope goes on to say that the separate parts of the equipment such as motors and switching devices are subject to EN 55014-1. Thus, equipment with motors / switching devices are subject to EN 55014-1 and the rf circuits are subject to EN 55022 EN55022 DOES NOT apply. A battery charger is not within its scope. This point was settled officially (but, one would have thought, unnecessarily) a long time ago. The Irish standards body asked CENELEC whether a washing machine containing a microprocessor was ITE or not. The official answer was that 'Function determines the applicable standard. A washing machine is a washing machine and the standards for washing machines [which happen to be EN55014-1-and -2] apply.' and the complete device is subject to EN55014-2. I guess one could argue that it is sufficient to reference EN 55014-1 and EN55022 on the DoC instead of EN 50081-1. Either way works for me since EN 50081-1 just points to the other documents. -- Regards, John Woodgate, OOO - Own Opinions Only. http://www.jmwa.demon.co.uk Eat mink and be dreary! --- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.

RE: Limitations on use and installation of Class A equipment in t he EU
Dan, It just sank in what you are talking about when you said that Germany requires a license. Before the EMC Directive became effective, Germany did require a license (general permit) for operation of a Class A device. However, that German ordinance was replaced by the national implementation of the EMC Directive. The directive requires that your equipment comply with the listed essential requirements. When you declare compliance with a harmonized standard such as EN55022, there is a presumption of compliance with the essential requirements. Since EN55022 has both Class A and Class B limits, you can comply with the essential requirements if you comply with either set of limits. However, you must observe the restrictions placed upon Class A equipment: no use in residential areas and must include the warning in the user manual.

RE: RTTE Directive
It can be confusing. Let's see if I can help. I will address the Directive from the point of view of transmitters. The essential requirements relate to three areas: safety, EMC and the radio spectrum. For safety and EMC, you have a choice - continue to follow the procedures in the LV and EMC Directives or follow the procedures in the RTTE Directive. If you choose the RTTE Directive, you will need to use a Notified Body if and only if the standards are not published in the OJ. Guess what? The safety standard for human exposure is not published. Therefore, I recommend that you choose to follow the procedures of the LVD. Under those procedures you do not have to use a Notified Body. Now to the radio spectrum. There are three possible paths o It is a receiver product - follow Annex II and self declare o A harmonized standard exists and it includes a test suite - follow Annex III and self-declare o A harmonized standard exists, but it does not include a test suite - follow Annex III and use a Notified Body o No spectrum standard exists - follow Annex IV and use a Notified Body Having followed the appropriate procedure, you may now issue the DoC and apply the CE marking to the product, DoC and container. Is your operating band harmonized? If so, proceed to market; otherwise, you must follow the country notification procedure prior to marketing. Good Luck! Richard Woods Richard Woods -- From: Courtland Thomas [SMTP:ctho...@patton.com] Sent: Thursday, June 21, 2001 4:09 PM To: emcpost Subject: RTTE Directive Hello group, After reading through the RTTE Directive for the fifth or sixth time, I am still not clear on the use of the notified/competent body and European representative. It seems to me that I can get all my testing done, whether it be my own internal testing or using an outside lab, and then just file the test reports. There is some mention of the notified body and representative, but not enough for me to feel it necessary to have either. I realize for equipment that doesn't fall under the RTTE Directive, the notified/competent body performs the assessment of the equipment to the particular standards, but isn't the intent of the RTTE Directive to eliminate this requirement and place that burden on the manufacturer? For some reason I just don't see the requirement for those entities after reading through the directive. Maybe someone else can give me their interpretation.

Richard, What is the test plan for making and breaking under load? In general, power supplies take a little bit of time to start up, so making contact under load is not going to be an issue. UL has specified a 200 cycle disconnect test and all they are concerned with is condition of the contacts afterward. They do not specify how fast you have to plug the supply from the connector, so this could be a factor. Typically, they have a short signal pin that must be fully seated for the supply to operate. Once you start pulling the supply, the signal pin breaks first and shuts down the high current before those contacts break. The slower you pull, the less likely you will draw an arc. Or course, the fast you pull, the shorter duration the arc. Regards, Glenn Lesmeister Product Regulatory Compliance Compaq Computer Corp.

A search in the PDF version of UL/CSA 60950 reveals nothing specific when searching for hot, swap, or power supply. A visual search of the TOC also reveals nothing specific. 2.6.5.4 deals with : Parts that can be removed by an operator Protective earthing connections shall make earlier and break later than the supply connections in each of the following: - the connector of a part that can be removed by an OPERATOR; - a plug on a power supply cord; - an appliance coupler.

RE: Clock Dithering
Be careful. IBM (perhaps Lexmark now) holds a patent on certain aspects of this technology. Richard Woods -- From: Binnom, Cyril A [SMTP:binno...@ems-t.com] Sent: Friday, June 15, 2001 10:07 AM To: emc-pstc Cc: McBride, James; Wismer, Sam; Massey, Doug C.; Davis, Brett A. Group, I am experiencing a EMI failure during testing and it has been isolated to the processor board in which the fundamental frequency is 66.6 MHz the 3rd harmonic that is our failure frequency is 199.8 MHz. We consulted the manufacturer of the board and they have come up with a spectrum spreading application for me to try. As I understand it, these type of applications work by essentially jittering the clock frequency in order to spread the energy over a wider band of frequencies. Thus the level at any particular frequency is reduced even though the overall amount of energy radiated is the same. The file they are sending me is a test application. If it works well enough to get the unit to pass test, they have the ability to enable the same application in the BIOS so it is always running. Does anyone have any experience using this type of application? Any opinions on its validity? To those that can attest to its validity, any pros or cons to the use of this application?

Richard Woods -- From: Hare, Paul [SMTP:ph...@pirus.com] Sent: Wednesday, June 13, 2001 2:42 PM To: emc-p...@majordomo.ieee.org Subject: Detachable AC Cordset Selection for the EU Hello group, I am in the process of specifying detachable AC cordsets for European distribution of my product. It uses an autoranging power supply (100-240VAC) and is rated for 12 A max with a C14 appliance coupler. I initially thought this would be a trivial task of matching plug and connector variations for each of the EU countries and specifying a 12 A cord. However, it looks like all the cordsets that are generally available with European connectors are rated for 10 A max. I am also lead to believe that the C14 coupler is rated for 15A in North America, but only 10 amps in Europe. Are electrons hotter on the east side of the pond?? Amongst my circle of compliance peers, there seems to be a difference of opinion as to what current rating the cordset should have. I would think that the current rating of any cordset I choose for Europe would need to be rated for 12A (Better safe than sorry, right?). But half of the people I've talked to say, But why? The current will be about half of the 12A max, or 6 amps, due to the higher line voltage. And after all, the mains voltage should be within 10% of nominal!! Therefore a 10A cordset is plenty good! If I had my way, I would special order a 12A cordset (And I guess this would change my appliance coupler?). But, it would be nice if I could buy an off-the-shelf 10A cordset because of pricing and availability issues. Any comments?

RE: [Fwd: Police radar gun]
Dave, I disagree on your conclusion that a police radar gun is not a communication device. The device has a transmitter and a receiver and an automobile acts as a transponder. The device communicates with itself. However, even if the automobile is not present, the transmitter can be active and can potentially cause interference. This device acts no different than RFID and anti-theft products that read tags on products, railroad cars, cattle, cars, and ID badges. And these systems are definitely considered to fall under the RTTE directive. Your only potential out on this one is the public security exemption.

RE: Product Safety: A Matter of Law or Litigation?
Doug, my recommendation is to obtain approval marks for the US and Canada due to the potential of litigation. You will have shown due diligence which may assist in limiting any liability issues. In the EU, however, they have no-fault liability - if someone is hurt by a defect in your equipment, you are at fault no matter what approvals you have. A safety approval in Europe is for useful for marketing purposes only. Richard Woods -- From: Massey, Doug C. [SMTP:masse...@ems-t.com] Sent: Monday, June 04, 2001 8:47 AM To: 'IEEE Forum' Subject: Product Safety: A Matter of Law or Litigation? Colleagues: I have been tasked with justifying the need for independent, third party evaluations of the safety of our company's products to applicable standards. Our company manufactures various ITE equipment, either handheld, battery powered devices, or ITE devices powered by vehicle batteries. In particular, the scope of the LVD states that it is applicable to devices rated 50-1000Vac or 75-1500Vdc; most of our products are below 75Vdc. We market these products in 35 countries; North America, the EU/EFTA, and others - in fact, pretty much all of the countries participating in the CB Scheme. In the US, OSHA regs justify this requirement, as our equipment is sold through direct channels solely for logistics applications - in other words, US workers will be using the equipment - it's not for general consumer use. TITLE 29--LABOR PART 1910--OCCUPATIONAL SAFETY AND HEALTH STANDARDS--Table of Contents Subpart S--Electrical Sec. 1910.399 Definitions applicable to this subpart. Acceptable. An installation or equipment is acceptable to the Assistant Secretary of Labor, and approved within the meaning of this Subpart S: (i) If it is accepted, or certified, or listed, or labeled, or otherwise determined to be safe by a nationally recognized testing laboratory; or (ii) With respect to an installation or equipment of a kind which no nationally recognized testing laboratory accepts, certifies, lists, labels, or determines to be safe, if it is inspected or tested by another Federal agency, or by a State, municipal, or other local authority responsible for enforcing occupational safety provisions of the National Electrical Code and found in compliance with the provisions of the National Electrical Code as applied in this subpart; or ... In the EU/EFTA, the justification is not so easy. As I mentioned earlier, the products are exempt from the LVD. The General Product Safety Directive, and the Product Liability Directive, do not give me an easy justification, such as in the case of the OSHA regs stated in US Federal Code. My company has always had all products evaluated to the -950 standards, but has observed that other manufacturers of similar equipment do not have their products evaluated to applicable safety standards, and CE mark their products based on compliance to the EMC Directive, but not to the LVD. I would greatly appreciate your insights, opinions, and assistance with this question. Doug Massey Safety Approvals Engineer LXE, Inc. Norcross, GA., USA Ph.

RE: UL Style Cable
I can comment on the CM series cables. They are specified in the National Electrical Code for Communications applications. CM is the general construction, but has limits as to where it can be used in the building. CMR is designed for use inside walls (R = Risers) and CMP is designed for use in air handling spaces (P = plenum). CMP can replace CMR which can replace CM. All of these cables can also replace their equivalent Class II or Class III cables - e.g., CMP can replace CL2P.

The definition of SELV in IEC 60950 contains no restrictions on energy; rather, voltage is the only issue. A note in clause 1.2.8.6 indicates that IEC364 has a different definition of SELV.

See 3.6 of UL 60950. Annex NAB clearly specifies that the connections to the centralized DC power system must meet the requirements for primary circuits as specified in section 3.2, however there are no requirements for disconnect devices or overcurrent protection specified in this annex. This equipment has operator replaceable fuses for over current protection on the power inputs and has numerous overcurrent devices in the PC assemblies. However, it does not have a disconnect device since it is intended for installation into telecom racks with other equipment that is similarly connected. A disconnect device is required for equipment connected to the AC mains, as specified in 2.7 of UL 60950, however there no requirements for disconnect devices for equipment connected to a secondary SELV source. The centralized DC power systems installed in these restricted access locations are provided with disconnect devices for overcurrect and fire protection. I'm not sure how you would specify the short circuit protection requirements for these systems, since they are not branch circuits covered under Article 240 of the National Electrical Code. Rick Meyette -Original Message- From: Tania Grant [mailto:taniagr...@msn.com] Sent: Wednesday, May 16, 2001 7:18 PM To: Richard Meyette; 'emc-p...@majordomo.ieee.org' Subject: Re: Disconnect Devices for Telecom Equipment Rick, A -48 volt source is considered a secondary circuit, but that does not necessarily make it a SELV circuit. I also don't believe that even if your equipment installation should be proven to be powered by a SELV circuit that the disconnect requirements of Section 2.6 do not apply. Here is why. Note that UL 60950 plainly states that connections to - and overcurrent protection for -d.c. powered equipment needs to meet the same sections as for a.c. main powered equipment. It stands to reason, therefore, that disconnection from whatever mains should also meet Section 3.4.3 (UL 60950) or 2.6 (I presume UL1950. 3rd edition). Annex NAB.2 states that ... connections to the centralized d.c. power system are subject to the requirements for PRIMARY CIRCUITS and shall be in accordance with 3.2 (AC MAINS SUPPLIES). Sections 2.7.1 and 3.2.1 in Annex NAE which address requirements for d.c. powered equipment refer you back to a.c. mains powered equipment. Also, reading the standard as a whole, Permanently connected equipment, whether a.c. or d.c., needs to meet the stated requirements. (All my references are to the UL 60950 edition.) There are many reasons why it can be considered unsafe not to have immediate access to a disconnect device for any equipment

Georg, we appeared to have a difference of opinion. You said that placing on the market took place when the products were transferred from the manufacturing plant to the warehouse even if both locations were owned by the same company. I had said that the warehouse could not be under the same control. I went back to review the Guide to the implementation of directives based on the New Approach and the Global Approach and found that you are correct. Clause 2.3.1 defines placing on the market and footnote 31 says the distribution chain can also be the commercial chain of the manufacturer. Thanks for teaching me something today.

Thank you for your reply, Paul. I visited the CCEE web site and found the catalogs of products that required safety certification. However, something is not clear to me. In the second catalog, OFF (office) equipment is listed, then in the next column several types of equipment are listed and then the applicable safety standard is listed. It is not clear as to exactly what OFF equipment must be certified. Is it all equipment in the OFF category as covered by the listed safety standard, or is it only the exact types of OFF equipment listed ?

However, if the rating is only 60 Hz, there may be the following frequency sensitive concerns: * Lower output from transformers due to insufficient core size * Slower speed fans causing cooling problems (if ac fans) * Higher ripple currents in the rectification filter capacitors may increase causing higher internal temperatures which will lead to lower life * Lower dc output from capacitor input rectification filter * Decreased low-line tolerance Richard Woods -- From: Ravinder Ajmani [SMTP:ajm...@us.ibm.com] Sent: Monday, May 14, 2001 11:49 AM To: emc-p...@ieee.org Subject: 120V appliance on 240V supply Hi, I am interested in knowing if a 120V, 60Hz microwave oven can be safely used on a 240V, 50Hz mains supply with a step-down transformer.
