3-5. Single UPS Operation 

3-5-1. Turn on the UPS with utility power supply (to Line mode)   

1)

 

Make  sure  mains  input  and  battery  are  connected  well,  and  the  battery  pack  breaker  is  at  “ON” 
position; Set the external mains input breaker to “ON” position, then the fan will be running and the 
UPS supplies power to the loads via bypass; (The UPS is operating in Bypass mode.)   

NOTE: When UPS is in Bypass mode, the output voltage comes directly from utility, so the load is not 
protected by UPS. To protect the precious load, the UPS should be turned on to Line mode. 

2)

 

When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn On”;
