5.1.7 Transferring to Maintenance Bypass Mode 

 

 

 

Strictly observe the following procedure to transfer the UPS to maintenance bypass mode. 
Otherwise, loads may power off. 

 

In maintenance bypass mode, the mains supplies power to the loads over the maintenance 
bypass. If the mains is abnormal, the loads may power off. 

Procedure 

Step 1

 

Transfer the UPS to bypass mode. 

Step 2

 

Turn on the maintenance bypass switch. 

If the maintenance bypass switch is locked, unlock it first. Rotate the maintenance bypass 
switch to the ON position. The system transfers to maintenance bypass mode, as shown in 

Figure 5-15
