5.7. 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. Reducing will prolong
backup time. To eliminate the risk of data loss, reduce loads before
batteries are depleted.
2. In Battery mode, pressing the Mute button to disable the buzzer.
3. The backup time may vary with different environment temperatures
and load types.
4. Battery discharge protection can be enabled or disabled through
LCD panel control. (Refer to LCD setting Section 6:09)
5.8. Test the Batteries
1. To check the battery status, press the “Test” button.
2. The UPSs default is set to perform a battery self-test automatically
once per week.
3. The self-test feature is programmable through battery software.
4. During the battery self-test, the LCD display and buzzer indication
will be the same as at Battery mode except that the battery LED is
flashing.
5.9. Turn Off the UPS with Utility Power Supply in AC Mode
1. Turn off the inverter of the UPS by pressing “OFF” button for at
least 0.5 seconds. The buzzer will beep once, and the UPS will
