Note:
Before connecting the battery, plug the unit into mains. Using a voltage meter measure Volts across
the Red (+) and Black (-) battery wires to check that the Charge voltage is between 13.6V-13.8V D.C.
Disconnect Mains power before wiring up the equipment to the unit.
The unit will create slight internal heat on all components including its battery. Ensure that the unit has
adequate ventilation when selecting the installation location.
The Battery Charge output is Current limited to approx 1A
and is suitable for batteries no bigger than 7A/H
+Positive 13.8V - 14.2V DC (Processor controlled charge rate )
Buzzer sounds :
Double Beep ever 30 seconds on AC fail
3 Second beep on power up
When battery reaches 10V, the unit cuts out
after the 2 Minute warning tone stops
AC Fail
Outputs + (Positive) for a AC fail condition
When AC is restored goes 0V (Negative)

LED Indication:
RED SOLID = 220VAC ON. Charging Constant Voltage
RED FLASHING = 220VAC ON Unit is trickle charging
OFF = 220VAC Power Failure
Installing a New Battery to the unit in a Power failure Condition
Connect a piece of wire from the Battery(+) to the POS (+) Input
for approx 5 seconds.
The Power-Supply will beep twice followed by another two beeps.
Once the Power-Supply has switched the Relay ON you may remove
