"Fault" indicator, red
In addition to the "Fault" indicator a text message can appear, showing the cause
of the fault. Basically any safety relevant fault leads to a shut down of the device
into the safe state. Try a restart as follows:
Press the "OFF" button - as soon as the device has been shut down, the "Power
ON" indicator goes off
After a waiting time of 10 s press the "ON" button
If the "Fault" indicator still lights up after this new start attempt, contact a Fronius-
trained service technician, for checking the device.
Another cause of the "Fault" indicator lighting up may be a low state of charge with-
in the integrated back-up battery. If this cause of the fault can be unambiguously
identified based on the text message, recharge the back-up battery using a suitable
charger. More information can be found under "Fault diagnosis" in the "Trouble-
shooting" section.
