turn on when the battery self-test starts; upon battery fault (battery not connected or battery failure), the FAULT 
indicator will turn on and the BATTERY indicator will blink, as shown in Figure 5-5. 

Note 

1. The battery state information will be refreshed after each time of battery self-test. Confirm the battery fault information of the 
self-test upon battery undercharge by conducting another time of self-test after the battery has been fully charged. 
2. Follow the order to start up the UPS: connect the battery, connect the mains and then press the ON/SILENCE key. 

 

5.5   Turning Off UPS 

Turning off UPS includes turning off UPS from Normal mode, turning off UPS from Battery mode and turning off UPS 
from Bypass mode. 

Turning off UPS from Normal mode 

Press and hold the OFF key for one second until the buzzer beeps, the UPS inverter stops operating, and transfers to 
Bypass mode. At this moment the MAINS indicator and BYPASS indicator will turn on; press and hold the OFF key for 
ten seconds, the UPS enters standby state. At this moment, the UPS is not powered off completely, and the MAINS 
indicator is on, as shown in Figure 5-6. If you need to power off the UPS completely, disconnect the mains input of the 
UPS. 

   

 

Figure 5-51  Indicators states 

Turning off UPS from Battery mode 

Press and hold the OFF key for one second, then the UPS is turned off, the output is terminated, the load is powered 
off and the BATTERY indicator is off, as shown in Figure 5-7. If you need to power off the UPS completely, press and 
hold the OFF key for ten seconds.
