Grounding the Power System (continued)

Cabling at the rear of the unit can be routed in and out of the cabinet

through the two cable ducts at the bottom of the unit or by removing the

break-away tab on the rear panel. (Refer to Figure 4-31 for location of the

break-away tab.)

A ground connector mounted on the side panel of the chassis provides an

earth-ground connection to the chassis. For an alternate location, you can

move the ground lug to the rear mounting bracket, as shown in Figure 2-14.

Figure 2-14 Grounding Connection and Alternate Location

Use the ground connection (Figure 2-14) to attach one end of a ground wire;

attach the other end to a nearby grounding rod that meets all electrical

specifications required for an earth ground. Use the shortest possible length

of #8 gauge copper wire, or equivalent braided cable, to make the

connection.

If the system is mounted in a cabinet or rack, use the same grounding

procedure. Ensure that a good cabinet or rack ground connection is achieved

by removing existing paint and attaching a #8 gauge copper wire (or

equivalent) using a bolt, washers, and nut as necessary.
