bypass breaker, so need to used external circuit breakers). The maintenance 
bypass supplies power to loads. 

 
 
 

o

 

Note

 

 

150kVA - 300kVA only have a manual bypass breaker. In manual bypass mode (

The 

manual bypass supplies power to loads

), dangerous voltages are present on 

terminal and internal Copper bar.

 

 

150kVA -300kVA need to use external 

circuit breakers (

Includes external input 

breaker, external bypass input breaker, external output breaker and external 
maintenance bypass breaker

). 

 

Warning

 

Before making this operation, read messages on LCD display to be sure that bypass 
supply is regular and the inverter is synchronous with it, so as not to risk a short 
interruption in powering the load.

 

Danger

 

If you need to maintain the power unit, wait for 10 minutes to let the DC bus capacitor 
fully discharge before removing the cover.

Switching

 the UPS into Normal Mode fromMaintenance Bypass 

Mode

 

These following procedures can transfer the load from the Maintenance Bypass to 
inverter output. 
1)

 

One by one to turn on the output breaker (Q4), input breaker (Q1), bypass input 
breaker (Q2), and then the system starts initializing. 

2)

 

After 30S, the static bypass turns on, the bypass indicator LED goes green, and the 
load is powered through maintenance bypass and static bypass. 

3)

 

Turn on the external battery breaker. 

4)

 

Turn off the maintenance bypass breaker and the load is powered through static 
bypass. 

5)

 

After 30S, the rectifier starts, the rectifier indicator LED goes green, and then 
inverter starts. 

6)

 

After 60S, the system transfers to Normal mode. 

 

o

 

Note

 

150KVA - 300KVA operation, please refer to chapter 5.3.2.

 

4.3

 

Battery Manual

 

If the battery is not in use for a long time, it is necessary to test the condition of the 
battery. Two methods are provided: 
1)

 

Manual Discharging test. Enter the menu Operate

as is shown i

Figure4-3 

and 

touch the icon “Battery maintenance”

the system transfers into the 

Battery mode for discharging. The system will stop discharging when the battery 
will have 20% of capacity or in low voltage. Users can stop the discharging by 

touching the “Stop

 

Test” icon
