The FUSE_OPEN alarm is activated when the optional inter-
nal electronic fuse (extra-rapid type) is opened.
The SHORT_CIRCUIT_CURRENT alarm is activated when
the peak current on the load exceeds the maximum permit-
ted value (corresponding to twice the device’s rated current)
during the softstart ramp or during the first power-on (with
softstart ramp disabled).

The parameter sets the number of automatic device restarts after a FUSE_OPEN or SHORT_CIRCUIT_CURRENT alarm. The device auto-
matically restarts in softstart mode. If the number of attempts exceeds the Fr.n value, the device remains disabled while awaiting manual
reset with the BUT front button or the serial communication command (bit 109).
Setting Fr.n = 0 disables automatic restart.
