Lucent Technologies 60V Small Broadband Power System J85500Q-1
5 - 4 Installation
Issue 4 October 1998
Control Unit
1. Identify and unpack the Alarm Control Unit (ACU),
EBM1 and the BPS.
2. Inspect for damage.
3. Remove the BPS faceplate.
4. Remove the ACU from the BPS.
5. Insert the ACU (EBM1) into the slot in the BPS. (See
Figure 5-2.)
6. In order to complete the remaining steps, do not replace the
faceplate on the BPS.
Plug-In Modules
General
1. Ensure that the proper modules have been ordered and
received.
2. Disconnect the power to the shelf by turning the ac service
circuit breakers off.
3. The On/Standby switch on the rectifier must be in the
Standby position.
4. Install the rectifier and the BPS by placing them on the
rectifier shelf and carefully sliding them toward the back
plane until its mounting screw prevents any further
backward motion. Do not seat the rectifier or the BPS. (At
this point, the BPS faceplate is not yet installed.)
5. The Low Voltage Shut-off function is pre-set in the factory
at 61 volts, with strap STR1 across positions 1 and 2. See
“Low Voltage Shut Off” in Section 6 for more
information.
Warning
•
High leakage currents are possible. Earth ground
connection is essential before connecting the commercial
ac power to the rectifier. Due to the hazardous voltage
levels, it is essential that the shelf is also reliably earth
grounded.
•
Interconnecting control/logic circuits are at hazardous
voltage levels with respect to ground.
