Nick I concur in the information you have already been given. In addition I would like to add from an EMI / EMC standpoint a hinged panel creates several points of vulnerability. Your EMC testing cycle may be extended because the your system may need to be tested with the door open and closed. Your ground impedance seen by the door will be different between open and closed. I would ask the mechanical designer if that is the hill they want to die on. There is usually a better way than mounting active components on the door.

What clause of what standard, code or regulation is being violated. This is the first piece of information you need in order to investigate the claim. If you can find that and report back, I am sure someone on this forum can help you out further.

For ease of construction, we often attach components to the access door of our industrial control panel enclosures. UL has evaluated our construction methods and certified us a UL508 Panel Shop. Criteria is that a solid earth ground is attached to the door, and all electrical cables are protected against damage. We are being told by a customer that electrical components are never allowed on a door, in compliance with CE. If UL finds it acceptable, I am not sure why it would be unacceptable for Europe. I have seen many enclosures in Europe with electrical components on a removable panel or door. Is the inspector exercising personal preference, or is there a compliance standard that backs up this decision to reject our wiring practices?
