4. Important Safety Warning (SAVE THESE INSTRUCTIONS)

CAUTION! The charger is designed to charge the specific voltage lead-acid battery. Please see

the specifications for the acceptable voltage range. Do not use these products on batteries
with other voltage ratings.
CAUTION! Some models may generate high current DC voltage to the battery being charged.
Do not expose the charger to the water, rain, snow or spray.

CAUTION! Do not open the charger. There are no user-replaceable parts inside of the unit.
Attention! Ensure at least 20 cm air space is maintained on all sides of the charger. During

operation, keep away from the materials that may be affected by high temperatures.

CAUTION! Never attempt to charge a frozen battery.
Attention hazardous through electric shock. To reduce the risk of electric shock, disconnect

both AC and DC power from the charger before attempting any maintenance or cleaning or
working on any circuits connected to the charger. Turning power switch off will not reduce the
risk.

mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes.

CAUTION! Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
CAUTION! A battery can present a risk of electric shock and high short circuit current. The

following precaution should be observed before replacing batteries:

1) Remove watches, rings, or other metal objects.

2) Use tools with insulated handles.

3) Wear rubber gloves and boots.

4) Do not lay tools or metal parts on top of batteries.
