12v power output
Terminal blocks are provided to connect to the system. The maximum current available
from the “Power output” terminals depends on the type of power supply and the batteries
used, shown in the table on the back page.
Auxiliary power supply (batteries)
Two connectors are provided marked BATT1 and BATT2. A third connector is fitted to the
D1532, marked BATT3. By default, the PSU assumes that all batteries will be fitted. If only
one is used, this must be connected to the BATT1 connector, and the configuration learned.
A second battery must be connected to the BATT2 connector, and the configuration
learned.
Battery learning
Battery learning can only be done when the AC power is applied and at least one battery is
connected to BATT1. The battery learn process is initiated by pressing the Learn button;
the Status LED will flash rapidly and the current battery configuration will be learnt into non-
volatile memory. The battery configuration will remain in memory even after a complete
power-down.
Battery protection
The batteries and electronic circuitry are protected against reverse polarity connected by a
self resetting electronic fuse. The batteries are also protected against deep discharge,
which will be invoked when the battery terminal voltage has dropped to 10.5v.
Battery monitoring
The batteries are monitored for low voltage, disconnection and load test. When more than
one battery is fitted, they are monitored individually.
Maintenance
This unit is to be used by service personnel only; there are no user serviceable parts. No
maintenance is required other than routine periodic testing and replacement of the standby
batteries. For further information on routine battery replacement, please contact your
battery supplier or manufacturer.
