Battery mode
When the UPS is operating during a power outage, the alarm beeps once every ten seconds and the indicator
illuminates solid.
The necessary energy is provided by the battery.
When the utility power returns, the UPS transfers to Normal mode operation while the battery recharges.
If battery capacity becomes low while in Battery mode, the audible alarm beeps faster.
This warning is approximate, and the actual time to shutdown may vary significantly; shutdown all applications on
connected equipment due to imminent UPS shutdown.
When utility power is restored after the UPS shuts down, the UPS automatically restarts.
End of battery backup time
All the LEDs go OFF.
The audible alarm stops.
Bypass mode
In the event of a UPS overload or internal failure, the UPS transfers your equipment to utility power. Battery mode is not
available and your equipment is not protected; however, the utility power continues to be passively filtered by the UPS.
The by-pass indicator illuminates in orange.
Depending on overload conditions, the UPS remains in Bypass mode for at least five seconds and will stay in this mode if
three transfers to Bypass occur within 20 minutes.
The UPS transfers to Bypass mode when:
the user activates Bypass mode through the front panel,
the UPS detects an internal failure,
the UPS has an overtemperature condition,
the UPS has an overload condition listed.
The UPS shuts down after a specified delay for overload conditions listed.
6.5 Return of AC input power
Following an outage, the UPS restarts automatically when AC input power returns (unless the restart function has been
disabled) and the load is supplied again.
6.6 Configuring battery settings
Automatic battery test
Automatic battery tests are done every month in constant charging mode. The tests frequency can be modified.
During the test, the UPS transfers to Battery mode and discharges the batteries for 10 seconds under load.
Battery mode is not displayed and battery low alarm is not activated during a battery test.
The battery test may be postponed due to bad conditions, or failed if battery is not ok.
Low battery warning
During discharge, the low battery alarm is activated if the remaining runtime goes below 3 minutes or less than the
setting capacity threshold (0% by default).
This threshold can be modified.
External battery setting
The number of Extended Battery Module is manually set in LCD menu.
Deep discharge protection
This setting is recommended to avoid damaging the battery. Warranty is void if deep discharge protection is
disabled.
