Connecting small battery holdover
Grounding to an AC-powered media gateway (J58890CH)
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 cabinet).
•
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.
Grounding to 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
2
) media gateway
GROUND wire to the media gateway ground terminal block. See
Figure 17, Typical media
gateway ground location,
on page 97 and
Figure 18, Power distribution unit (J58890CH),
on page
98.
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.
4
Route the media gateway GROUND wire to the single-point ground block at the AC load center
and connect.
NOTE:
If the media gateway is located remotely (in a separate room or building), connect the
media gateway GROUND wire to an approved ground.
5
Repeat connecting each media gateway to the single-point ground block.
6
At the AC load center, connect a 10 AWG (#25) (6 mm
2
) wire to the single-point ground block.
This ground wire will later be tie-wrapped to the trunk cables and connected to the Coupled
Bonding Conductor (CBC) ground block at the main distribution frame (MDF).
The coupled bonding conductor (CBC) wires are installed and terminated in
