4.4.2 Shut Down Parallel System

Generally, it isn't recommended to start or close parallel system frequently.

Shut down all load.

Press the "

" button of each unit for 1s to shut down the unit of parallel system.

Switch off the related breakers of each unit (when daily use, the breakers can be not closed).

----End

4.4.3 Exit Parallel System Online

When one UPS in parallel system fault, it will exit from parallel system automatically with sound &

light alarm. at that time, perform the operations shown in 2032624074.0.264318872 . , the fault UPS

will be exited from parallel system completely to achieve online hot maintenance or replacement.

Switch off breaker in the
distribution box, which connects
with the faulty UPS.

Close the fault UPS
according to shutdown
procedures.

Exit parallel system online

When the parallel system works normally, it's better not to exit the output from parallel system before

the unit closed, or the power system will be abnormal.

4.4.4 Add New UPS into Parallel System Online

When it has to add one or more UPS into parallel system, perform the operations shown in

2032624074.26.264318872 . . When the added UPS works steadily, it will add into parallel system

automatically and achieve current- sharing.

Install the added
UPS completely

Start the added UPS
according to the startup
procedures successively

Switch on the breaker of the
distribution box that connected
with added UPS

Add new UPS into parallel system
