1-18 ◆ Section 1: Installing the Cabinet
Ground the cabinet by connecting a 14 AWG wire from the ETH lug to a known earth ground, such
as a copper plate or grounding rod.
Be cautious when using a cold water pipe that it's completely copper and does not change to
PVC/vinyl chloride pipe.
When installing a COIU or DIOPU PCB, connect the grounding wire of the PCB to the PBXG ter-
minal plate and then run a grounding wiring from the PBXG terminal plate to a known earth ground
using 14 AWG grounding wire.
The ETH and PBXG grounds should be separate - they should not be combined.
From the factory, the FG is already connected to the AC power source. No action is required.
