output wires, the output breaker, and the parallel cables. 

2)    Open the input and output breakers of each UPS. Connect the input wires, output 

wires and battery wires.   

3)    Connect each UPS one by one with the parallel cables.   

4)    Close the battery breakers and the input breakers of all of the UPSs in the parallel 

system in turn.   

5)  Turn on each UPS in turn and observe their display. Make sure that each UPS 

displays normal and all the UPSs transfer to the INV mode normally.

transfer switch will perform a transfer of the load from the inverter to the maintenance bypass 

source, with no interruption in power to the critical AC load.

nearest office or customer service center, or the head quarter of the company, do not attempt to 

repair the UPS by the user, otherwise may cause dangerous and breakdown the UPS.
