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 system. 

 

Pay special attention to these two types of notices used in this manual. 

 

WARNING 

Failure to heed this warning may cause injury to persons and damage to equipment. 

 

CAUTION 

Failure to observe this warning may result in damage to equipment and improper functioning of the charger. 

 

WARNING 

 

 

The charger is designed for in-door use. Protect the charger from ingress of water. 

 

This charger is made to charge only properly sized lead acid batteries. 

 

Charging other types of battery or under-sized lead acid batteries may cause fire or explosion. 

 

Install the charger in accordance with all local codes. 

 

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

 

Do not remove casing of the charger, there is no user-serviceable parts inside. 

 

Do not charge the battery on boats. Remove the battery and charge on shore. 

 

Never attempt to charge a frozen battery. 

 

Never attempt to charge a damaged battery. 

 

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

 

Never place the charger on top of a battery. 

 

Never  smoke,  use  an  open  flame,  or  create  sparks  near  battery  or  charger  during  normal  charging  operation  as  batteries  may 
giveout explosive gas. 

 

Do not charge batteries in an enclosure (box-in) due to possible explosion of entrapped explosive gas. 

 

Use of accessory not recommended may cause risk of fire, electric shock. 

 

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

 

If the charger does not work properly or if it has been damaged, unplug its AC and DC connection. 

 

CAUTIONS 

 

 

Refer to battery manufacturer’s specific recommended values for battery type settings and float voltage setting. 

 

Fix the charger to a stable surface using the holes at the flange. 

 

Ensure all ventilation ports are not obstructed for efficient fan cooling, keep loose soft material or paper off at the bottom of the 
charger. 

 

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