Connect the Safety Ground

Proper grounding of the G700 Media Gateway installation safeguards the system, users and service personnel by providing protection from lightning, power surges, AC mains faults, power crosses on central office trunks, and electrostatic discharge (ESD).

Local electrical installation codes must be followed when installing G700 Media Gateways.

WARNING: Connection of both grounds (through the AC Power Cord and the Supplementary Ground Conductor) is required for safe operation of the G700 Media Gateway.

WARNING: An improper ground can cause electrical shock as well as equipment failures and service outages.

Attach the Ground Wires

Begin _____________________

1. Remove the ground screw on the rear of the chassis adjacent to the ground symbol:
   
2. Place the ring terminal of the 10 AWG (4.0 mm²⁾ Supplementary Ground Conductor on the screw.
3. Replace the ground screw to the chassis and securely tighten the screw such that it cannot be loosened without the use of a tool.

If the ground block is being used: The ground block is usually provided and mounted by the customer electrician.

4. Cut the Supplementary Ground Conductor (which has one end attached to the grounding screw on the chassis) to the length needed to terminate it into one of the terminals of the ground block. Do not coil the Supplementary Ground Conductor.
5. Attach one end of the additional 10 AWG (4mm²⁾ ground wire to one of the terminals in the ground block and the other end to an approved ground.
6. Cut this ground wire to the length needed to reach the approved ground. Do not coil this wire.

If the ground block is not being used, simply:

7. Attach the Supplementary Ground Conductor to an approved ground.
8. Connect the AC power cable to the inlet receptacle on the rear of the chassis.

You have now mounted the fully equipped G700 Media Gateway in the rack, cabled units together as described in the planning documents, and connected to electrical ground conductors. When all the units are mounted, cabled, and grounded, you are ready to apply power.
