3-4. Single UPS Operation 

1. Turn on the UPS with utility power supply (in AC mode)   

1)    After power supply is connected correctly, set the breaker of the battery pack at 

“ON” position (the step 

only available for long-run model). Then set the line input breaker at 

“ON” position(for dual input unit, 

also set the bypass input breaker at “ON”). At this time the fan is running and the UPS enter to power 
on mode for initialization, several seconds later, UPS operates in Bypass mode and supplies power to 
the loads via the bypass.   

NOTE: 

When UPS is in Bypass mode, the output voltage will directly power from utility after you switch 

on  the  input  breaker.  In  Bypass  mode,  the  load  is  not  protected  by  UPS.  To  protect  your  precious 
devices, you should turn on the UPS. Refer to next step.   

2)    Press and hold 

the “ON” button for 0.5s to turn on the UPS and the buzzer will beep once.     

3)  A  few  seconds  later,  the  UPS  will  enter  to  AC  mode.  If  the  utility  power  is  abnormal,  the  UPS  will 

operate in Battery mode without interruption. 

NOTE: 

When the UPS is running out battery, it will shut down automatically at Battery mode. When the 

utility power is restored, the UPS will auto restart in AC mode.   

2. Turn on the UPS without utility power supply (in Battery mode) 

1)    Make sure that the breaker of the battery pack is at 

“ON” position (only for long-run model).   

2)    Press 

the “ON” button to set up the power supply for the UPS, UPS will enter to power on mode. After 

initialization UPS will enter to No Output mode, then Press and hold 

the “ON” button for 0.5s to turn on 

the UPS, and the buzzer will beep once. 

3)    A few seconds later, the UPS will be turned on and enter to Battery mode. 

3. Connect devices to UPS 

After the UPS is turned on, you can connect devices to the UPS. 

1)    Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total load 

level.   

2)    If  it  is  necessary  to  connect  the  inductive  loads  such  as  a  printer,  the  in-rush  current  should  be 

calculated carefully to see if it meets the capacity of the UPS, because the power consumption of this
