October 2002
NOTE:
The type of power required is shown on the media gateway’s rear door.
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
2
), copper, stranded wire.
• Bond all approved grounds at the single-point ground to form a single grounding
electrode system.
Ground AC Load Center 50 ft. (15.2 m) or Less
from Media Gateway
1 At the bottom rear of the first media gateway, connect a 6 AWG (#40) (16 mm
2
) media
gateway GROUND wire to the media gateway ground terminal block. See ‘‘Typical
Media Gateway Ground Location’’ on page 74.
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
2
) media gateway GROUND wire to the media gateway ground terminal block.
