WARNING

 3.4.1.

Turn on the UPS with utility power (in AC mode)

•

  After power supply is connected correctly, set the breaker of the battery 

pack at “ON” position (only in case of external battery packs presence). Then 

set the line input breaker at “ON” position. At this time the fan is running and 

the UPS enter to power on mode for initialization, several seconds later, UPS 

operates in Bypass mode and supplies power to the load via the bypass.

NOTE! 

When UPS is in Bypass mode, the output voltage will draw power from utility 

after you switch on the input breaker. In Bypass mode, the load is not protected 

by the UPS. To protect your precious devices, you should turn on the UPS. 

•

  Touch “CONTROL” and select “UPS on/off” icon. It will show “Turn on 

UPS?” in screen and select “Yes”. Refer to On/Off UPS screen.

•

  A few seconds later, the UPS will enter into AC mode. If the utility is 

abnormal, the UPS will operate in Battery mode without interruption.

NOTE! 

When the UPS is running out of battery, it will shut down automatically in Battery 

mode. When the utility is restored, the UPS will auto restart in AC mode.

  3.4.2.  Turn on the UPS without utility power supply (in Battery mode)

•

  Make sure that the two strings of batteries are connected correctly at 

UPS’s ”+,GND,-” terminals and the breaker of the battery pack is at “ON” 

position (only in case of external battery packs presence).

•

  Press the   

POWER

 button to set up the power supply for the UPS. UPS will 

enter to power on mode. After initialization, UPS will enter to No Output mode.

•

  A few seconds later, the UPS will be turned on and enter to Battery mode.

  3.4.3.  Connect devices to UPS

After the UPS is turned on, you can connect devices to the UPS.

•

  Turn on the UPS first and then switch on the devices one by one. The 

LCD panel will display total load level.

•

  If it is necessary to connect the inductive loads such as a printer, the in-

rush current should be calculated carefully to see if it meets the capacity of 

the UPS, because the power consumption of this kind of loads is quite big.
