After you perform "startup operations" on UPS 1 to UPS 

n

 one by one, UPS 1 to UPS

 n

 are starting. If 

you do not perform "startup operations" on the other UPSs in 5 minutes, UPS 1 to UPS 

n

 enter normal 

mode, and the other UPSs supply no power. 

Step 6

 

When the parallel system runs properly, close the general output circuit breaker Q (provided 
by the customer) and then branch output circuit breakers (provided by the customer), and start 
the loads. 

----End 

5.3.2 Shutting down the Parallel System 

Shutting down a Single UPS in the Parallel System 

Step 1

 

Perform "shutdown operations" twice on a single UPS within 30 seconds in the parallel 
system. The UPS is shutting down. The other UPSs continue working. 

 

The UPSs in the parallel system have shut down supply no power (the mains indicator, bypass indicator, 
and battery indicator are Off). 

Step 2

 

Open the UPS AC input circuit breakers K1 and the AC output circuit breaker Q1. After all 
indicators turn off and fans stop, the UPS shuts down. 

Step 3

 

Open the external battery circuit breaker (if there is), or disconnect battery cables. The UPS 
exits the parallel system. 

 

To merely shut down the UPS, perform 

Step 1

 only. 

----End 

Transferring the Parallel System to Bypass Mode 

Perform "shutdown operations" on each UPS in the parallel system. All inverters shut down at 
the same time, and the parallel system transfers to bypass mode. 

Shutting down the Parallel System 

Step 1

 

Shut down the loads. 

Step 2

 

Perform "shutdown operations" on each UPS in the parallel system. All inverters shut down at 
the same time. The parallel system transfers to bypass mode. 

Step 3

 

Open the following circuit breakers in sequence for each UPS: UPS AC input circuit breakers 
K1 and K2, general AC input circuit breaker K, UPS AC output circuit breakers Q1 and Q2, 
and general AC output circuit breaker Q. After all indicators turn off and fans stop, the UPSs 
shut down, and the loads power off. 

 

Perform 

Step 3

 when there are two mains inputs. In the case of one mains input, you need only to open 

the following circuit breakers in sequence for each UPS: UPS mains input circuit breakers, general 
mains input circuit breaker, UPS AC output circuit breakers, and general AC output circuit breaker.
