Protection:

• Thermal overload protection of motor and

electronics.

• Monitoring of the intermediate circuit voltage

ensures that the inverter cuts out if the inter-

mediate circuit voltage gets too high or too

low.

• If a mains phase is missing, the inverter will

cut out when a load is placed on the motor.
