Cisco 3745 User Manual

12
• For EN/IEC 60950-compliant grounding, use AWG 18 (1 mm
2
) or larger wire and a user-supplied ring terminal.
To connect the chassis to a reliable earth ground, perform the following steps:
Step 1 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 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size.
Step 3 Attach the ground lug or ring terminal to the chassis as shown in Figure 4 or Figure 5. 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).
Step 4 Connect the other end of the ground wire to a grounding point at your site.
