Operating mode/status
When the input voltage exceeds the acceptable range or during a power failure, the
UPS will start supplying power from the battery while the alarm will beep every 4
seconds.
When input voltage is within the acceptable range and bypass is enabled, turn off the
UPS in order to transfer the unit to Bypass mode. The alarm beeps every two minutes
in this case.
Description
When UPS is in AC mode or CVCF mode, press and hold the Test key for 0.5 second.
The UPS will beep once and start performing the “Battery test”. The line between I/P
and inverter icons blinks while the diagnostics is in progress. This operation is used to
check the battery status.
Description
In the event of abnormal operation, the LCD panel will display the corresponding fault
message on the LCD panel.
