Dear List members, I am trying to determine if our products fall under the scope of IEC/EN 61000-3-2 and am seeking your comments/advice in that regard. We manufacturer electro-mechanical products that control register, color, and other process parameters on commercial web-offset printing presses. These are auxiliary industrial control devices. The input current and voltage ratings of the products fall within the scope of the Standard. These products are not on the open market and are not sold to the general public. They can only be obtained by commercial printing companies and only through our sales department. Typically, in a large printing plants (where our products are installed), the supply utility brings in a very high power source or sources. Then, distribution and step-down is done within the plant via the plant's own switchgear & controlgear. Thus, my line of thinking is that our products are not connected to the "public low-voltage distribution system" described in the Standard's Scope - Clause 1. So, using that logic, I'm now wondering if our products are excluded from the 61000-3-2 requirements. If not, the 2nd paragraph in Clause 4 seems to provide an exception for "Professional Equipment". I do believe our products would fall under the definition of Professional Equipment provided in 3.15. Although, I could also say the same for certain Medical Devices, Test Equipment, Motor Drives, and many other electrical devices. We'd prefer to not have to instruct our users in the instruction manual to "ask the supply utility for permission to connect". When considering the typical plant power scheme, I wonder if the printing plant is actually it's own supply utility. If that's the case, then the statement in the instruction manual wouldn't provide much value because the user would essentially have to ask himself for permission to connect. Has anyone else run into this dilemma or am I just missing something? What is the group's opinion on whether or not our products (described above) must comply with the requirements of 61000-3-2? All comments/feedback will be welcomed. Thanks in advance.
