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 12, Figure 13, or Figure 14, or attach the ring
terminal to the ground-lug bracket as shown in Figure 15, Figure 16, or Figure 17. 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, the attachment would be similar for an AC power supply.
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.
