4. Battery mode operation

1) When the UPS is in Battery mode, the buzzer will beep according to different battery capacites. If
the battery capacity is more than
voltage drops to the alarm level, the buzzer will beep quickly (once every sec) to remind users that
the battery is at a low level and that the UPS is about to automatically shut down. Users can 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, you have to shut down all loads as
soon as possible to protect the devices from load failure and/or data loss.
2) In Battery mode, users can press the Mute button to disable the buzzing sound.
The backup time of the long-run model depends on the external batteries' capacity.
3)
4) The backup time may vary with different environment temperatures and load types.
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 using the LCD panel control. (Refer to 3-7 LCD setting section)

5. Test the batteries

1) If you need to check the battery status when the UPS is running in AC mode/CVCF mode, press
the "Test" button to have the UPS do a battery self-test.
2) Users can also set battery self-test using the monitoring software.

6. Turn off the UPS with the utility power supply in AC mode

1) Turn off the UPS inverter by pressing the "OFF" button for at least 0.5s. The buzzer will beep once
and the UPS will switch to Bypass mode.
NOTE 1: If the UPS has been set to enable the bypass output, it will bypass voltage from the utility
power to the output sockets and terminal even though the UPS is switched off (inverter).
NOTE 2: After turning off the UPS, please be aware that the UPS is working in Bypass mode and
that there is risk of power loss for connected devices.
2) In Bypass mode, output voltage from the UPS is still present. In order to cut off the output, switch
off the input breaker. A few seconds later, there is no display shown on the display panel and UPS
is completely off.
