Installation Instructions
PSBC12XX Charger
Description
The PSBC12XX charger is a power supply unit installed in outdoor/indoor
cabinets or standard 19” racks, which is used for charging batteries and powering
equipment directly. Overcurrent and overvoltage protection is provided to prevent
damage that might be caused by a faulty battery and/or external load. Temperature
compensation is employed to enhance battery life.
The PSBC12XX charger supports battery sets, which are charged as long as AC
power is on. When AC power is off, the batteries supply current directly to the
load.
If alarm monitoring, event logs or detailed PSBC12XX charger parameters are
required, the PSM1006 GUI software supplied with the PSBC12XX charger can
be installed on a PC which connects to the PSBC12XX charger controller. For
more information, refer to the BroadAccess PSBC 12XX-X Charger Management
Software User Guide.

Parts Required
Warning: The AC line must be protected by a 32A “D” type circuit breaker.
Warning: Each battery set must be protected by a 50A “C” type circuit breaker.
Before commencing installation, unpack and identify all parts listed in Table 4.
Table 4. PSBC12XX Charger Installation Part List
Item Part Description Quantity
1 Alarm cable 1
2 Load cable Up to 6
3 Battery cables Up to 2
4 Temperature sensor cable Up to 2
5 RS-232 cable or Ethernet 1
Tools Required
The following tools are required for installation:
•Phillips screwdriver
Installation
Note: Ensure that ventilation around the unit is adequate. Allow at least 50 mm of
clearance on both front and rear side to enable free air flow through the unit's
ventilation holes.
1. From rack front, position the unit at the required height, taking into account
other cages to be placed in the rack.
2. Insert and tighten all four bolts securing PSBC12XX charger to rack.
Cable Connections
Caution: Use caution when routing wires and cables. Avoid severe bending and routing
over sharp edges. Use grommet material when possible to avoid wear to cable
insulation.
Warning: Insulated cable terminals must be used for the connection of loads and battery to
the output and alarm terminals.

1. Connect the ground cable from the outdoor cabinet to the PSBC12XX charger
ground terminal.
2. Place temperature sensors near the batteries in the battery compartment. Route
the sensor cable to the PSBC12XX charger and connect sensor cable connector
to the PSBC12XX charger rear panel temperature sensor connectors.
Note: Instructions for routing the temperature sensor through the cabinet to the
batteries appear in the installation instructions provided with the cabinet.
3. Connect alarm cable connector to PSBC12XX charger rear panel alarm
connector. Route cable and connect to MDF distribution blocks external alarms
terminal as required.
4. Connect the battery sets to the PSBC12XX charger rear panel battery terminals
using the battery cables as follows:
Red cables to + terminals on PSBC12XX charger and batteries
Black cable to - terminals on PSBC12XX charger and batteries
5. Connect loads to the PSBC12XX charger rear panel load connectors using the
load cables as follows:
Load 1 (usually Cage 1):
♦Red cable: from load + terminal to PSBC12XX charger load
