Cisco Systems VG202XM, VG204XM manual Crimping a Ground Lug onto the Ground Wire

Chapter 3 Installing the Voice Gateway

Installing the Ground Connection

Warning This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Warning Use copper conductors only. Statement 1025

Before You Begin

Locate a suitable ground.

Tip Using a multimeter, measure the resistance between various possible ground locations, such as between the ground of a junction box (outlet) and the ground of a power tap, between the ground of a junction box and a metal water pipe, between the chassis and the ground of a power tap, and between the chassis and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 Ohm.

Procedure

Step 1 Strip one end of the ground wire to the length required for the ring terminal.

Step 2 Crimp the ground wire to the ground lug or ring terminal, using a crimp tool of the appropriate size. (See Figure 3-4.)

Step 3 Attach the ring terminal to the chassis as shown in Figure 3-5. For a ring terminal, use one of the screws provided. Use a number 2 Phillips screwdriver to 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.
