5. Battery mode operation
1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacity. If the
battery capacity 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 (the UPS would cut off the programmable
output terminal automatically when the programmable timer function is enabled). 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 to disable the buzzer.
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.
5) When setting backup time for 16.5 hours (default value from LCD panel), after discharging 16.5 hours, UPS
will shut down automatically to protect the battery. This battery discharge protection can be enabled or
disabled through LCD panel control. (Refer to 3-7 LCD setting section)
6. Test the batteries
1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode/ECO mode, you
could press the “Test” button to let the UPS do battery self-test.
2) To keep the system reliable, the UPS will perform the battery self-test automatically periodically. The
default setting period is once per week.
3) Users also can set battery self-test through monitoring software.
4) If the UPS is at battery self-test, the LCD display and buzzer indication will be the same as at Battery mode
except that the battery LED is flashing.
7. Turn off the UPS with utility power supply in AC mode
1) Turn off the Inversor of the UPS by pressing “OFF” button for at least 0.5s, and then the buzzer will beep
once. The UPS will turn into Bypass mode.
NOTE 1: If the UPS has been set to enable the bypass output, it will bypass voltage from utility power to
output sockets and terminal even though you have turned off the UPS (Inversor).
NOTE 2: After turning off the UPS, please be aware that the UPS is working at Bypass mode and there is risk
of power loss for connected devices.
2) In Bypass mode, output voltage of the UPS is still present. In order to cut off the output, switch off the
internal output breaker and input breaker. A few seconds later, there is no display shown on the display
panel and UPS is complete off.
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.
9. Mute the buzzer
1) To mute the buzzer, please press the “Mute” button for at least 0.5s. If you press it again after the buzzer is
muted, the buzzer will beep again.
