3 Stage Battery Charger

User Manual

Keep this manual in a safe place for quick reference at all times.

This manual contains important safety and operation instructions for correct use of the battery charger. Read through the manual and

pay special attention to the markings and labels of the charger, battery and equipment connected to the battery.

WARNING :

Failure to observe this warning may result in injury to persons, damage to equipment and improper functioning of the Charger.

This range of Battery Chargers are designed for in-door use. Protect the charger from all liquids.

Only charge properly sized batteries.

Refer to battery manufacturer’s recommendation for battery type setting and float voltage setting.

Mount the charger to a solid base and in accordance with all local codes.

Wear protective goggles and turn your face away when connecting or disconnecting the battery.

Make sure all charger ventilation vents are unobstructed for efficient fan cooling.

Do not charge non-rechargeable batteries.

Charging wrong type or under-sized batteries may cause fire or explosion.

Do not use the charger if it has been dropped or damaged.

Do not remove charger casing as there is no user serviceable parts inside. 

Do not attempt to charge a frozen battery 

Do not attempt to charge a damaged battery.

Do not place the charger on a battery.

Do not smoke, use an open flame or create sparks near battery or charger during normal charging operation as batteries may give 
out explosive gases.

Do not charge batteries in an enclosure due to possible explosion of entrapped explosive gases.

Disconnect the mains supply before connecting or disconnecting the leads to the battery.

If the charger does not operate properly or if it has been damaged unplug the AC and DC connections.

If longer output charging cable is required, make sure the cable diameter is adequate for the cable length.

CAUTIONS:

When charging in Calcium mode disconnect the load from the battery as high charging voltage (15.5V) may cause damage to
connected equipment.
