The single-phase, 4-wire, 120/240 VAC supplying 208 — 240 VAC can supply 60 Hz power to the AC
load.This source has 2 hot wires, 1 ground wire, and 1 neutral wire (J58890CE).
Either of these power sources can supply 50 Hz power to the AC load:
•
Non-US 5-wire, Y, 220/380 VAC. This source has 3 hot wires, 1 neutral wire, and 1 ground wire.
•
Non-US Delta, 4-wire, 220 or 240 VAC. This source has 3 hot wires and 1 ground wire (describes
the power sources and required AC input power).

Grounding an AC-powered media gateway (J58890CE)
Grounding is relatively simple for an 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 media gateway).
•
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 an AC load center 50 feet (15.2 meters) or less from 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 ground terminal block. See
gateway grounding wiring diagram,
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 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.
