Grounding the Chassis
You must connect the voice gateway chassis to a reliable earth ground; the ground wire must be installed in accordance with
local electrical safety standards.
• For NEC-compliant grounding, use size AWG 14 (2 mm
• For EN/IEC 60950-compliant grounding, use size AWG 18 (1 mm
terminal.
• To ground the chassis, you will need a crimp tool and a number 2 Phillips screwdriver.
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 voice gateway chassis and the ground of a power tap, or between the chassis and the ground of a junction
box. A good ground connection should read between 0.0 and 0.5 Ohm.
Procedure
Strip one end of the ground wire to the length required for the ring terminal.
Step 1
Crimp the ground wire to the ring terminal, using a crimp tool of the appropriate size.
Step 2
Step 3
Attach the ring terminal to the chassis as shown in
number 2 Phillips screwdriver, and tighten the screws to a torque of 8 to 10 in-lb (0.9 to 1.1 N-m).
