Connecting The Safety Ground; Attaching The Ground Wires - Avaya G350 Installing And Upgrading

Installing the Avaya G350 Media Gateway

Connecting the safety ground

Proper grounding of the G350 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
DANGER:
Ground Conductor) is required for safe operation of the G350.
!
WARNING:
An improper ground can cause electrical shock as well as equipment failures and
WARNING:
service outages.

Attaching the ground wires

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 mm
ground screw.
3. Replace the ground screw on 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
1. 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.
2. Attach one end of the remaining 10 AWG (4 mm
the ground block and the other end to an approved ground.
3. Cut this ground wire to the length needed to reach the approved ground. Do not coil this
wire.
Note:
The ground block is for use with more than one G350 in the rack. If the ground
Note:
block is to be used, you must supply it and have it installed by an electrician.
If the ground block is not being used
1. Attach the Supplementary Ground Conductor to an approved ground.
2. Connect the AC power cable to the inlet receptacle on the rear of the chassis.
