Installing the Avaya G350 Media Gateway
Step 3: Attach ground conductors
Connect the safety ground
Proper grounding of the G350 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 the G350.
!DANGER:
Connection of both grounds (through the AC Power Cord and the Supplementary Ground Conductor) is required for safe operation of the G350 Media Gateway.
! WARNING:
An improper ground can cause electrical shock as well as equipment failures and service outages.
To attach the ground wires:
1Remove the ground screw on the rear of the chassis adjacent to the ground symbol.
2Place the ring terminal of the 10 AWG (4.0 mm2) Supplementary Ground Conductor on the screw.
3Replace 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 has been purchased: The ground block is provided for use with more than one G350 in the rack. It is usually mounted by the customer electrician.
4Cut 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.
5Attach one end of the remaining 10 AWG (4 mm2) ground wire to one of the terminals in the ground block and the other end to an approved ground.
6Cut 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:
1Attach the Supplementary Ground Conductor to an approved ground.
2Connect the AC power cable to the inlet receptacle on the rear of the chassis.
You have now mounted the fully equipped G350 Media Gateway and connected to electrical ground conductors. You are now ready to connect power.
