CAUTION
Avoid exceeding min. and max. input voltage values not to cause irreparable
damages to the equipment.
NOTE
Isolated supply output is protected by a self-resetting fuse capable of preventing
the inverter internal power supply unit from damaging due to a short-circuit.
Nevertheless, if a short-circuit occurs, the inverter could lock and stop the motor.
