Coming to over load due to
inverter off
When the inverter is turned off manually, the load will
exceed the power capacity.
Coming to Interval transfer
due to inverter off
When the inverter is turned off manually, the load will
exceed the power capacity.
Inverter invalid due to
over load
The load exceeds the capability of the single or parallel
modules.
It indicates the Master Inverter.
Latched load transfer to bypass as a result of too many
successive transfers within the current hour. Automatic
reset attempt within the next hour.

Alarm Information
Rectifier detected faulty. Rectifier and inverter and
charger shut down.
Rectifier Over Temperature
The temperature of heatsink is too high to keep the
rectifier running. Charger and inverter shut down.
Inverter Over temperature
The temperature of the inverter heatsink is too high to
keep inverter running.
Rectifier failure due to over-current
Failure of input thyristor
Battery discharge thyristor
failure
Failure of battery discharge thyristor
Battery charge thyristor failure
Failure of battery charge thyristor
At least one of the cooling fans fails. Rectifier and
inverter and charger shut down.
Rectifier, inverter and battery converter are shutdown due
to high DC bus voltage.
Rectifier, inverter and battery converter are shutdown
due to low DC bus voltage.
If the difference between positive DC bus and negative
DC bus exceeds 30V, this warning shall occur.
Rectifier could not be started due to low DC bus voltage
Input Neutral line missing
If Input Neutral line is missing or disconnected while the
UPS is in operation, the UPS will generate Neutral line
failure alarm and go into Battery mode.
The polarity of the battery is reversed.
Positive Battery Charger
fault
The positive battery Charger is fault. The charger will
be shut down.
