Figure 2-4: Chassis Ground Lug Location

Once you have installed the unit, run a ground wire (14 AWG protective conductor)
between the chassis ground lug and a known good earth ground.

Use stranded copper wire to earth ground and keep the length as short as possible.
 Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).

Run the ground wire so that any routing bend in the cable has a minimum radius of 30.48
cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
Note: If your installation includes multiple chassis, you must individually ground each chassis.
For more information on grounding or if your installation uses cathodic protection, refer to Site
Considerations for Equipment Installation, Grounding, and Wiring (D301452X012) .
Internal System Bus Ground
The internal system bus ground provides an internal reference to system power negative or ground
input. Users cannot access this ground.
