The display panel in battery mode is shown in the following diagram Fig.3-2. The battery
LED and the INV LED are turned on. The displayed number of the battery level LEDs will
be turned on in accordance with the battery capacity. Note that the load level LEDs in
utility power mode will indicate the level of the battery capacity in battery mode instead.
1) When the UPS is running in battery mode, the buzzer beeps once every 4 seconds.
If the “ON” button on the front panel is pressed for more than 1 second again, the
buzzer will stop beeping (in silence mode). Press the “ON” button once again for
more than one second to resume the alarm function.
2) When the battery capacity decreases, the number of the battery capacity LEDs
turned on will be reduced. If the battery voltage descends to the alarm level, the
buzzer will beep once every second to remind the users of insufficient battery
capacity and the UPS is soon going to shut down automatically. Then the load
operations should be carried out promptly and the loads should be eliminated one
by one.
