9.5. Battery mode operation
1. When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the battery ca-
pacity is more than 25%, the buzzer will beep once every 4 seconds; If the battery voltage drops to the alarm
level, the buzzer will beep quickly (once every sec) to remind users that the battery is at low level and the UPS will
shut down automatically soon. Users could switch off some non-critical loads to disable the shutdown alarm and
prolong the backup time. If there is no more load to be switched off at that time, you have to shut down all loads as
soon as possible to protect the devices or save data. Otherwise, there is a risk of data loss or load failure.
2. In Battery mode, if buzzer sound annoys, users can press the Mute button for 5 seconds to disable the buzzer. It
will be restored when the mains power is newly available.
3. The backup time of the long-run model depends on the external battery capacity.
4. The backup time may vary from different environment temperature and load type.
9.6. Battery test
1. If you need to check the battery status when the UPS is running in Normal mode/Converter mode/ECO mode, you
could press the ON/Mute button for 5 seconds to let the UPS do battery self-test.
9.7. Turn off the UPS with utility power supply in Normal mode
1. Turn off the inverter of the UPS by pressing OFF button for at least 2 seconds, and then the buzzer will beep once.
The UPS will turn into standby mode and cut off the output keeping the batteries charged.
2. Remove the input cable to completely shut down the UPS.
9.8. Turn off the UPS without utility power supply in battery mode
1. Turn off the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep once.
2. Then UPS will cut off power to output and there is no display shown on the display panel.
