Neil, Alan, All, As Neil says, this legislation applies to "fixed installations". The printer and the PC will be certified by the manufacturer, as will a network switch, server etc. The network that is built from all these has never been certified (and does not need to be) but the installation must not cause interference.
However, once the fixed installation is "identified" all the equipment collected at that point and that can contribute to the EM characteristics form part of that installation. Obviously, the standard items that you buy will be certified as normal apparatus. Either the custom equipment, specific to the installation, will have a performance agreed with the supplier, or what the supplier has assessed as needed. The only disagreement (if there is any) is where Neil refers to the intent to control interference from "built-in plant". I do not see where the UK Regulations, or the Directive, limit the scope of the responsible person's responsibility only to those portions of the installation that contain "built-in plant". For instance, not all the commercial test equipment, assembled as a system that is specific to the needs of the manufacturer, that has been created by the manufacturer, is allowed to cause interference. How many times has it been said that CE+CE does not equal CE? What is the point in making a person responsible for the "built-in" equipment and not the rest of the potentially interfering devices that are bought together? Remember a fixed installation means "a particular combination of several types of apparatus and, where applicable, other devices, which are assembled, installed and intended to be used permanently at a pre-defined location" I think that the "several types of apparatus" neatly catches everything that falls within the boundary of the fixed installation. Anyone else with an interpretation? Regards Tim 6239 desk A1S77 P Please consider the environment before printing this email.

Keep this in mind if you answer this message. Alan, This part of the legislation affects 'fixed installations', not movable equipment such as printers and PCs, which will be compliant in their own right. It is intended to control interference from built-in plant and machinery, IT networks and such like. In other words it is concerned with the equipment that is fixed in the premises and not capable of being completely assessed prior to installation. The intent is to promote good practice in the construction and installation of such equipment. The good practices may include such aspects as construction of enclosures, provision of filtering, separation of power and data cables, shielding of power and data cables, earthing and bonding, etc.. The requirement is simply that these good practices are both considered and documented as evidence of due diligence. Best regards Neil R.

Out of (more than passing) interest - why do you think it affects offices and factories? (Apart from the obvious need for a factory/office not to interfere with local services, passing aircraft, etc - but that was always the case anyway.) Is there some particular wording of the Directive or Regulations that implies factories & offices are included? Let's face it - bringing in one new printer or PC for your office affects the factory/office EMC "profile", and if every office is going to have to document simple things like that it is going to cost industry a fortune! Almost all EU Directives are aimed at products for a free market, and making sure they are up to the job. I find it hard to believe that the Directive was intended to include industry's factories and offices, especially considering the costs that will be invoked. Hmmm?
