GROUNDING THE CABINETS

Connecting the System Ground (Figure 1-35)

The SG, PBXG, ETH and FG ground lugs are located on the right side of the cabinet. The

side panel must be removed in order to access them. There is also an FG lug on the inside of

the cabinet, on the lower left.

1. In each cabinet, connect the SG (Signal ground) lug to the verified Earth Ground point using

14 AWG (2mm

) wire.

2. In each cabinet, connect the ETH (Earth ground) lug to the verified Earth Ground point lug

using 14 AWG (2mm

) wire.

3. From the factory, the FG (Frame ground) is already connected to the Earth point of the AC

power source.

4. The PBXG (PBX ground) is optional, see description below
