General Grounding Requirements

For AC Input: Two safety grounds are required to ensure safe operation of the G700 Media Gateway —
the ground conductor that is part of the AC power cord and the field-installed green/yellow conductor
referred to as the Supplementary Ground Conductor. Both safety grounds must be connected to an
approved ground. If a power cord accompanies the G700, use that cord whenever possible.
For DC Input: The +48Vdc lead provided for DC power input to the G700 Media Gateway must be
grounded at the source to an approved ground. The -48Vdc is the active lead. Both leads must be floating
at the input to the G700. In addition, the Supplementary Ground Conductor must be installed on the G700
and connected to an approved ground.
The customer must select a location for the G700 Media Gateway installation that is no more than 50 feet
(15 m) from an approved ground. If this location requirement is not met, the customer must contact a
licensed electrician to install a Supplementary Ground Conductor per Article 250 of the National
Electrical Code (NEC).
!
WARNING:
If the installation location is greater than 50 feet (15 m) from an approved gr ound, d o
not install the Avaya G700 Media Gateway until a licensed electrician is present to
install a Supplementary Ground Conductor.
A 55-foot (16-m) Supplementary Ground Conductor is provided with the equipment, and is constructed
of 10 AWG (4.0 mm2) wire, with an insulated ring terminal crimped to one end that is suitable for the #8
(M4) stud/screw on the rear of the G700 chassis.
The customer will need to provide a means of connecting this Supplementary Ground Conductor to an
approved ground according to Article 250 of the National Electrical Code (NEC).
