Lucent Technologies 60V Small Broadband Power System J85500Q-1
Issue 4 October 1998
Installation 5 - 3
Power Shelf
If a 60V/60 Hz CPS shelf is already mounted in a cabinet or
frame, proceed to “AC Input Wiring.”
When installing a CPS shelf, ensure that adequate space is
available for mounting the shelf. The shelf requires a minimum
of 10.75 inches of vertical height, including a minimum of 1 inch
above and 1 inch below the unit for cooling. Twelve inches of
space in front of the shelf is required for insertion and removal
of the shelf power units. The shelf may be mounted in either
19-inch framework or 23-inch framework in cabinets which
requires bracket extensions.
When installing batteries, refer to the appropriate product
manuals. Follow all safety precautions.
1. Mount the CPS shelves and battery modules in the frame.
Screws are required in all mounting holes and should be
torqued to a minimum of 30 inch-pounds.
AC Input Wiring
The CPS 60-volt rectifier is powered from a branch circuit.
Note
Before working on any BPS output beyond the cabinet
distribution/breaker panel, turn off the associated 60V/60 Hz
ac service circuit breakers.
Warning
AC input voltages are provided to the CPS via input cable.
Ensure that the circuit breaker for the ac input is disconnected
while installing this equipment. The BPS has dc inputs from
the rectifier and the batteries. Disconnect all before working
on the BPS.
Note
Supply appropriate mounting hardware for your application.
Note
Branch circuits to the rectifier should be protected using
circuit breakers sized as required by the National Electric
Code. The maximum rating of the circuit breakers used to
protect the ac wiring is 15 amperes.
