Installing the Chassis Ground LugA terminal lug is provided with the AT-SBx3112 Chassis to provide a
permanent connection to a good earth ground. This permanent connection
is required to insure a common ground path is provided for all line cards
and power supplies installed in the chassis.
To install the # 10 AWG ground wire, perform the following procedure:
1. Prepare an adequate length of stranded grounding wire
(10 AWG) for the ground connection.
2. Strip the grounding wire as shown in Figure 28.

3. Detach the ground lug that is attached to the chassis by removing the
two screws on the rear of the chassis as displayed in Figure 29.
