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 non-exposed 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 1-35 on page 1-72 for DEFINITY ONE single cabinet routing, Figure
1-36 on page 1-73 for DEFINITY ONE two cabinet routing. To connect and route
the power cords:
1. Ensure the circuit breakers at the AC load center are
OFF
.
2. Connect the cabinet to an “unswitched” or “always on” electrical outlet.
