Check Grounding And Potential Difference; Site Environment Review - Eneo IAM-6MC1001M0A 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.

2.3. Site environment review

• Check the environment in which EPoC device is installed.
• The cable between the EPoC devices must be installed apart from high-voltage power cable.
• In environments where cross-talking or signal interference occurs, separate settings may be required, such as
network grouping (See how to set Joining).
• In environments where power noise occurs (e.g. Installation on elevator), it is necessary to use a model
specifically designed to prevent noise.
• EPoC devices are for Indoor Use and must be installed in a separate watertight enclosure when installed
outdoors.
• Check that the environment is suitable for the operating temperature and operating humidity of the equipment.
