4 "Inverter" light
◗ light off: inverter OFF.
◗ light flashing green: inverter starting, inverter ON but not connected to the load.
◗ light shines green: normal inverter operation.
◗ light shines red: inverter fault, the stored alarm indicates one or several of the following faults:
- inverter shutdown due to inverter output voltage outside specified tolerances,
- protection fuse at the inverter output (FUS) blown,
- abnormally high inverter-output transformer temperature,
- abnormally high inverter temperature,
- output-voltage fault (amplitude or phase) (parallel UPSs),
- fault, non-calibration or non-personalization of the electronic control board for the inverter,
- fault on the electronic power-supply board.
5 "Load" light
◗ light off: load not supplied.
◗ light shines green: load supplied via the inverter or the bypass AC source (via the static bypass).
6 Buzzer
The buzzer sounds in the following situations:
◗ load supplied by the bypass AC source.
◗ load on battery.
◗ operating problems.
It sounds slowly and discontinuously for a minor problem or when the inverter is on battery power.
When the alarm "LOW BATTERY SHUTDOWN" is activated, the buzzer sounds more rapidly. Finally, if the inverter
shuts down, the beep is loud and continuous. The buzzer may be reset by pressing a button. If the buzzer is reset,
a higher level alarm will set it off again.
