3-3. Audible alarm
3-4. Single UPS Operation
1. Turn on the UPS with utility power (On grid/ AC mode)
1) After making sure that the power supply connection is correct, set the input breaker to the “ON” position first. At this point,
the fan will start running while the UPS supplies power to the load via the bypass. The UPS is now operating in Bypass mode.
Note: When the UPS is in Bypass mode, the output voltage will directly power the load from utility after you have switched on
the input breaker. In Bypass Mode, the load is not protected by the UPS. To protect your load devices, you should turn on
the UPS as explained below.
2) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
3) After a few seconds, the UPS will enter into the AC mode. In case of abnormal utility power, the UPS will transfer to battery
mode operation to provide uninterrupted power to the outlets.
Note: In battery mode, the UPS will shut down automatically when the remaining charge is low. Once the utility power is
restored, the UPS will restart automatically in AC mode.
2. Turn on the UPS without utility power (Battery mode)
1) Press and hold the ON button for 0.5 second to power on the UPS. The buzzer will beep once.
2) After a few seconds, the UPS will be turned on and begin operating on “off-grid” or Battery mode.
3. Connecting devices to the UPS
After the UPS is turned on, you can connect devices to the unit.
1) Turn on the UPS first and then start switching “on” one load at a time, only after all of them have been plugged into the unit.
The total load level will be displayed on the LCD panel.
2) Should you need to connect inductive loads, such as a monitor or a laser printer to the UPS, the start-up power should be
used for calculating the capacity of the UPS, as energy consumption increases during initial power on.
