Grounding And Potential Difference; Apply Surge Protector - Eneo IAM-6MC1001M0A User Manual

3.4. Grounding and Potential Difference

EPoC device is basically grounded through the AC power cord of the adapter, so there is no need to ground
separately.
If there is a potential difference between the camera(specially metal housing camera) and ground (metal surface), PSE
of the EPoC transmitter cannot detect camera's PD correctly and PoE output will not operate properly. In this case, it
is necessary to check if there's potential difference between the camera body or metal surface and EPoC transmitter.
If there's potential difference on the camera and DC ground of the EPoC transmitter, it is necessary to isolate camera
body from metal surface using insulated panel (Wood or Plastic) and insulated screw.

3.5. Apply Surge Protector

In case of general surge protector for analog video, the Maximum Continuous Operating Voltage is under DC5V and
this surge protector is not compatible with EPoC devices which transfer 57VDC power via cable.
When it is necessary to install surge protector, make sure that the maximum continuos operating voltage of the surge
protector should be over 57VDC.
