Temperature & Safety Protection:
INTERNAL OVERHEAT PROTECTION: The charger is equipped
with built-in overheat and overload electronic circuit protection
TIMER PROTECTION: Charger provides the maximum charging
time for each charging stage. In the event it is wired to recharge a
larger than recommended battery, charger will stop charging after
maximum stage recommended time and the RED LED will be FLASH
slowly. At this point, Battery must be disconnected.
REVERSE POLARITY: Charger has reverse battery protection. (Red
LED ON, while output leads are connected backwards), Disconnect
and correct connection to battery.
SHORT CIRCUIT PROTECTION: Charger will turn off upon
detecting a short circuit (Red LED ON.

ECO MODE:
If AC power is connected, and the battery is not connected, the charger
will automatically go into ECO mode. Input power draw in ECO mode is
less than 1.5W (0.04kWh per day).
Power consumption in maintenance mode is 0.05kWh per day.
CHARGING INSTRUCTIONS:
STEP 1 - Pre Charge:
Battery & Electrolyte Level Check
Check the battery electrolyte level (Only for Flooded or WET
battery).
If necessary, remove the vent caps and add distilled water so the
levels are halfway between the upper and lower fill lines.
Check the battery label if it is 12V battery or 24V batteries etc.
STEP 2 - Connect Charger to Battery
If the battery is out of the vehicle:
Connect the Red lead from the charger to the positive (+) battery
terminal.
Connect the Black lead from the charger to the negative (-) battery
terminal.
If battery is still in the vehicle, determine if the vehicle is positively
or negatively earthed.
If Negatively earthed (Most Common) – First connect the Red (+)
battery charger lead to the Positive (+) battery post and then connect
the Black (-) battery charger lead to the vehicle’s chassis and away
from the fuel line.
If Positively earthed – First connect the Black (-) battery charger
lead to the Negative (-) battery post and then connect the Red (+)
battery charger lead to the Vehicle’s chassis and far away from the fuel
line.
STEP 3 – Connect Charger to Power (115Vac / 230Vac)
Connect the battery charger to AC mains powered socket.
The Charger will automatically start when AC power is connected
and switched on.
(Note: If the Fault Indicator LED illuminates Red, please check your
connections as it’s likely that the Positive and Negative leads are
reversed. Refer to Trouble Shooting page for further information)
STEP 4 – Disconnect Charger from Battery
If the battery is out of the vehicle:
Switch OFF and remove the AC power socket from the outlet.
Remove the black lead and then the red lead.
Check electrolyte levels if possible.
(As they may need topping up with distilled water after charging)
If the battery is in the vehicle:
Switch OFF and remove the AC power socket from the outlet.
Remove the lead from the vehicle chassis.
Remove the lead from the battery.
