5. INDICATION 

AND 

CONTROL 

5.1  Battery level LEDs 

The battery level LEDs show the voltage level both in back-up mode and in normal 

mode.    When the LED indicates 20% of the capacity in back-up mode, it means that 

the UPS is going to shut down; for the length of backup time left, it will depend on the 

load.    While when all five LEDs light in normal mode, it means that the battery is fully 

charged. 

5.2  Special status LEDs 

The 

Replace Battery

 LED would be on when the UPS battery is no longer useful and 

must be replaced.     
When the 

Alarm Off

 LEDs comes on, the UPS will not emit beep during back-up mode 

or when battery needs to be replaced.   However, the low battery alarm and over load 

alarm will still sound for urging user to leave computer without any data loss.     
The 

Charging

 LED would be on when the charger is charging the battery.  While the 

battery voltage is low in normal mode, the charger will keep on quick charging, when the 

battery voltage is high, the charger is keeping on for 4 seconds by every 24 seconds for 

trickle charging.   
The 

Boost

 LED would be on when the UPS is connecting a low utility voltage.    The loads 

receive normal power. 
The 

Buck

 LED would be on when the UPS is connecting a high utility voltage.  The 

loads receive normal power. 

5.3  Auto self-test function: 

In normal mode of UPS, turn on your computer and push the button on the front panel 

for self-test.    The UPS will simulate a power outage and transfer your load to the UPS 

battery.  If low battery warning sounds during the test, it means that the battery set is 

weak and requires extended recharge.  If replace battery warning sound, it means 

that the battery set is damaged and requires replacement.
