Do not expose the unit to rain or any form of moisture.
Avoid operation in direct sunlight and dust contaminated environments.
Ensure the units AC input supply is isolated.
Remove the terminal cover ensuring the cables are fed through the corresponding
apertures when making connections.
Ensure the AC input selector switch is in the correct position and connect the 110V or 230V
AC input supply.
Make necessary remote fault alarm and/or manual boost connections.
Connect the battery to the B-OUT (battery negative) and B+OUT (battery positive) terminals.
Always ensure the battery is of the correct type and number of cells.Note the alarm circuits
power-up when the battery is connected.
Switch on the AC input. After a short delay charge current will flow to the battery.
As the batteries charge the output current will reduce;
High output current = discharged battery, low output current = charged battery.
When the battery has fully charged its voltage can be checked with a DVM across the
battery terminals.

If the float voltage is adjusted from factory default then the alarm system MUST be
re-calibrated, following the instructions below.
10 APPENDIX A - Automatic Calibration Routine

OTE
:
The battery MUST be disconnected from the charger before proceeding.
Connect a DVM to the B+ / B- Out terminals of the charger. Set the float voltage to the desired
level by turning the 'Vfloat' multi-turn potentiometer.
Press and hold the ‘PROG’ push-button, all LED’s turn Red. Continue to hold for 10 seconds
until all
LED’s turn Green then release the push-button.
Set the boost voltage to desired level by turning the 'Vboost' multi-turn potentiometer.
Operate and release the push-
button again, the controller switches to float mode and all LED’s
are Red. Automatic calibration now commences.
After approximately 30 seconds the auto-calibration is complete and all LED's should be green
to indicate normal mode.
