Connecting Large Battery Holdover - Avaya G650 Installing

Checking commercial power and connecting AC power
check the AC power using a KS-20599 digital voltmeter (DVM) (or equivalent).
To check commercial power and connect the AC power:
1
Set the DVM to the 250 volt range.
2
Carefully measure the voltage between the two electrically hot leads of the receptacle.
3
Verify the meter reads 106 to 128 VAC or 200 to 240 VAC. If not, have a qualified electrician
correct the problem.
4
Measure the voltage between the neutral and ground side of the receptacle. The ground wire is
green.
5
Verify the meter reads 0 VAC. If not, have a qualified electrician correct the problem.
6
Be sure the main power on the front to the power distribution unit is OFF.
7
At the rear of the power distribution unit, set all carrier circuit breakers OFF.
8
Set all media gateway power modules
9
Plug the AC power cable into the receptacle.

Grounding to an AC-powered media gateway (J58890CH)
AC-powered media gateway. Basically, the media gateways connect to the single-point ground terminal
block located at either the AC load center or to a separate single-point ground block wired to the AC load
center (or optional AC protector cabinet).
•
The approved ground wire must be a green (or green with yellow stripe), 6 AWG (#40) (16 mm
copper, stranded wire.
•
Bond all approved grounds at the single-point ground to form a single grounding electrode
system.
Grounding to an AC load center 50 feet (15.2 meters) or less
from media gateway
To ground to an AC load center 50 feet or less from the media gateway:
1
At the bottom rear of the first media gateway, connect a 6 AWG (#40) (16 mm
GROUND wire to the media gateway frame ground terminal block. See
gateway ground location,
2
Route the media gateway GROUND wire to the single-point ground block at the AC load center
and connect.
3
At the bottom rear of the next media gateway (if provided), connect a 6 AWG (#40) (16 mm
media gateway GROUND wire to the media gateway frame ground terminal block.
4
Route the media gateway GROUND wire to the single-point ground block at the AC load center
and connect.
5
Repeat connecting each media gateway to the single-point ground block.

NOTE:
If the media gateway is located remotely (in a separate room or building), connect the
media gateway GROUND wire to an approved ground.
