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 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,
64.
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.
