8. Turn off the UPS without utility power supply in Battery mode 

1)    Touch “CONTROL” and select “Turn off UPS” icon to turn off the UPS. Refer to “UPS on/off” screen. 
2)    Then UPS will cut off power to output terminals. 

9. Mute the buzzer 

1)    Touch  “SETTING”  and  select  “BASIC”  item.  There  are  two  events  available  to  mute.  Refer  to 

“SETTING” screen. 

2)    Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for details.   

10. Operation in warning status 

1)    When LCD screen shows “Fault Mode” and the buzzer beeps once every second, it indicates that 

there are problems for UPS operation. Users can read the warning message(s) from “DATA LOG” 

menu. Please refer to the Chapter 4 for details.   

2)    Some warning alarms can’t be muted unless the error is fixed. Please refer to section 3-3 for details. 

11. Operation in Fault mode 

1)    When the buzzer beeps continuously, it means that there is a fatal error with the UPS.    Users can 

get the fault code from “DATA LOG” menu. Please refer to the Chapter 4 for details. 

2)    Please check the loads, wiring, ventilation, mains, battery and so on after the fault occurs. Don’t try 

to turn on the UPS again before solving the issues. If the problems persist, contact the distributor or 

service personnel immediately. 

3)    In case of an emergency, shut off connections from mains, external battery, and output immediately 

to avoid possible damage to the UPS or equipment.   

12. Operation in maintenance mode   

This operation should only be performed by maintenance personnel or qualified technicians.     

When the UPS needs to repair or service and the load could not be shut off, the UPS needs to be put into 
maintenance mode.   
1) First, switch off the UPS. 
2) Then, remove the cover of maintenance bypass switch on the panel. 
3) Turn the maintenance switch to “BPS” position. 
 

3-6. Parallel Operation 

1. Parallel system initial startup 

Please make sure that all of the running UPSs are parallel models and have the same configuration. 
1)    Turn on each UPS in AC mode respectively (Refer to section 3-4(1)). Then, measure the inverter 

output voltage of each phase for each UPS with a multi-meter. Calibrate the inverter output voltage 

by configuring inverter voltage adjustment (Refer to SETTING 

 Miscellaneous screen) in LCD 

menu until the inverter output voltage difference of each UPS is within 1V or less. 

2)  Turn off each UPS (Refer to section 3-4(7.)). Then, follow the wiring procedure in section 2-4.   
3)  Remove the cover of parallel share current cable port on the UPS, connect each UPS one by one 

with the parallel cable and share current cable, and then replace the cover. 

4)    Turn on the parallel system in AC mode: 

a)

 

Turn on the line input breaker of each UPS. If using dual-input unit, please also turn on the 

external bypass input breaker. After all UPSs enter into bypass mode, measure the output 

voltage between two UPSs for the same phase to make sure the phase sequence is correct. If 

these two voltage differences are near to zero, that means all connections are met. Otherwise, 

please check if the wirings are connected correctly. 

b)

 

Turn on the output breaker of each UPS. 

c)

 

Turn on each UPS in turns. After a while, the UPSs should enter into AC mode synchronously 

and then, the parallel system is now complete.
