4.5 Alarm codes
Using a sophisticated self-diagnosis system, the UPS is able to check its own status and any anomalies and/or faults
which may occur during normal operation and display them on the display panel. If there is a problem, the UPS signals
the event by showing the code and the type of active alarm on the display.
A
LARMS
“
Minor” problems which reduce performance or prevent certain functions from being used.

AULTS
Faults are normally preceded by an alarm signal and their scale leads to the power-off of the inverter and the load being
powered by the bypass line.
