Check Ac Power; Approved Grounds - Avaya S8700 Manual

Check AC Power

Each RMC uses an auto-ranging (85 to 264 VAC) power supply, 47 to 63 Hz, 330 Watts, 4.5
Amps (100 to120 VAC) or 2.3 Amps (200 to 240 VAC), at 500 VoltAmps (VA).
The AC power source can be 1 phase of 120 VAC with neutral (100 VAC for Japan) with
15-Amp circuit breaker, or 1 phase of 220 or 240 VAC (200 VAC for Japan) with 10-Amp
circuit breaker. The AC cord uses a NEMA 5-15P plug or an IEC 320 plug.
Before powering up the system, check the AC power in the equipment room using a KS-20599
digital voltmeter (DVM) (or equivalent).
To check AC power:
Measure the AC voltage between the hot and neutral sides of the receptacle.
1
Depending on the AC power source, verify that the meter reads 90 to 132 VAC or 180 to
2
264 VAC. If not, have a qualified electrician correct the problem.
3 Measure the voltage between the neutral and ground sides of the receptacle.
Verify that the meter reads 0 VAC. If not, have a qualified electrician correct the
4
problem.
5 When finished, set the AC main circuit breakers to OFF.

Approved grounds

An approved ground is the closest acceptable medium for grounding the building entrance
protector, entrance cable shield, or single-point ground of electronic telephony equipment. If
more than one type of approved ground is available on the premises, the grounds must be
bonded together as required in Section 250-81 of the National Electrical Code.
!
WARNING:
Make sure that the media gateway has a reliable earth ground connection, whether the it is
connected directly to a branch circuit or to a power distribution strip. In addition, the
media gateway requires a media gateway ground connection directly to an approved
ground.
Grounded Building Steel — The metal frame of the building where it is effectively grounded
by 1 of the following grounds: acceptable metallic water pipe, concrete encased ground, or a
ground ring.
