J Install and cable a CMC1 cabinet
Check AC power and ground for CMC1
364 S8100 Installation and Upgrades
November 2003
Install coupled bonding conductor
The coupled bonding conductor (CBC) provides mutual inductance coupling between the CBC and the
telephone cables exposed to lightning. The conductor can be a 10 AWG (#25) (6 mm
2
) wire tie wrapped
to the exposed cables, a metal cable shield around the exposed cables, or 6 spare pairs from the exposed
cable.
For a high-rise building, connect the CBC to an approved building ground on each floor. To provide the
coupled bonding protection:
1 Connect one end of the conductor to a telephone cable building entrance protector ground that is
connected to an approved ground.
2 Route the conductor next to the exposed telephone cables being protected until it reaches the
cross-connect nearest to the telephone system.
3 Position the unexposed telephone cables at least 12 inches (30.5 cm) away from exposed
telephone cables whenever possible.
4 Terminate the other end to the single-point ground block provided for the telephone system.
Connect and route the power cords
!
WARNING:
The AC power cord may connect to a properly rated power-distribution unit, individual AC power
receptacles, or to a UPS.
See Figure 66, Routing a CMC1’s AC power cord to power-distribution unit,
on page 365 for CMC1
single-cabinet routing, Figure 67, Routing two CMC1s’ AC power cords to power-distribution unit,
on
page 366 for CMC1 2-cabinet routing. Routing power cords for a 3-cabinet configuration is similar to
routing the 2-cabinet configuration.
To connect and route the power cords:
1 Ensure the AC load center’s circuit breakers are OFF.
2 Connect the cabinet to an “unswitched” or “always-on” electrical outlet.
