Step 2
Strip one end of the ground wire to the length required for the ground lug or terminal.
–
For the NEBS ground lug—approximately 0.75 in. (20 mm)
–
For user-provided ring terminal—as required
Step 3 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 4 Attach the ground lug to the ground-lug bracket as shown in Figure 3-33, Figure 3-34, or Figure 3-35,
or attach the ring terminal to the ground-lug bracket as shown in Figure 3-36, Figure 3-37, or
Figure 3-38. For the ground lug, use the two screws with captive locking washers provided. For a ring
terminal, use one of the screws provided. Use a number 2 Phillips screwdriver, and tighten the screws to
a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
Where a DC power supply is shown, AC power supply attachment is similar.
Diagonal attachment of the ground lug to the bracket provides clearance for the RPS power cable.
Step 5 Connect the other end of the ground wire to a suitable grounding point at your site.
