Check Grounding And Potential Difference - Eneo IAM-6MC1001MTA User Manual

2.2. Check grounding and potential difference

EPoC equipment is basically grounded through the power cord of the adapter, so there is no need to ground
separately.
However, EPoC equipment supports PoC (Power Over Coax) function and the transmitter is powered by the power
source connected to the receiver and the end-device is powered by the transmitter through the PoE output feature.
At this time, if there is a potential difference between the end-device and the transmitter, the transmitter may not
recognize the PD (Powered Device) of the end-device correctly, and the PoE output function of the transmitter may
not work properly.
Therefore, it is necessary to make sure that the end-device is normally grounded, and that there's the potential
difference between the end-device and transmitter.
