CONNECTION PROCEDURE
1
Check input and output voltages of system, ensure that they match the equipment.
2
Connect battery /batteries to
BATTERY
+
and
BATTERY
-
terminals. Although there is built in reverse
polarity protection, under some circumstances reverse polarity connection will not only result in the
rupture of the internal battery protection fuse but destroy the input circuitry of the unit.
3
The ECB and battery circuit may be tested at this point. To close the
ECB
with no mains power pre-
sent, briefly short together the
BATTERY
–
ve
and
LOAD
–
ve
terminals. The battery voltage will
then appear at the load terminals,
BATT LOW
relay energises &
BATT SYSTEM OK
LED turns on. The
POWER OK
LED stays on for about 30s. Disconnect one battery lead briefly to open the ECB.
4
Connect load/s to
LOAD
+
and
LOAD
-
terminals.
5
To minimize the volt drop at the output connections always use all the terminals provided by linking
them together.
6
Place temperature sensor probe near or on batteries.
7
Connect input power. Charger should be fully operational at this stage.
ALARM & BCT RELAYS
Relay contacts shown in
de
-
energised
state (ie. when there is a fault condition).
Alarm relays are
energised
when power supply is operating normally.
BCT
relay is energised when battery
condition test is in progress.
OUTPUT FUSES/ MCB RATING
The battery circuit is the one which has the highest fault current potential and fuses/MCBs should be correctly
rated for the wiring used.
FRONT PANEL LEDS

BATTERY SYSTEM OK:
LED on:
Battery present and above V batl.
Note:
If the battery condition test function is enabled, pushing this switch
for approx. 2 sec will manually initiate a battery condition test.
POWER OK:
LED on:
Input power present
LED off:
No input power or charger in standby mode
STANDBY:
LED on:
Charger in standby mode (no output from charger)
Note:
Push standby button to turn off charger, this allows load to run off bat
tery. Push button again to turn on charger.
