6. UPS Maintenance

6.1  Battery Replacement 

When  the  UPS  is  started  up  or  a  self-test  is  executed,  the  battery  replacement  symbol  on  the  LCD  panel  may 

appear because of a weak or dead battery.

 

1.

If the battery replacement symbol on the LCD panel appears, charge the UPS for at least 8 to 10 hours.

The symbol should disappear after the self-test function has executed.

2.

If the battery replacement symbol stays on after charging, unscrew the battery cover, replace the battery

with a suitable replacement from see Table F, and then press the ON button.

CAUTION! 

The UPS will not provide any output power if the start-up procedure has not completed properly even 

though the input power cord is connected to the wall receptacle. 

CAUTION! 

The battery is heavy, pull the battery out onto flat, stable surface. 

CAUTION! 

Do not disconnect the batteries while the UPS is in the backup mode. 

CAUTION! 
Use caution when replacing live batteries. 

CAUTION! 
See the user's manual for battery disposal instructions. 

CAUTION! 

Lead acid batteries can be a chemical hazard. 

CAUTION! 
The battery can be an energy hazard. Use maintenance free batteries. 

CAUTION! 
Risk of explosion if battery is  replaced by an incorrect type. Dispose of used batteries according to the 

instructions. 

CAUTION! 

Risk of shock. This UPS receives power from more than one source. Disconnection of the AC source and 

DtC source is required to de-energize this unit before servicing.
