motor is equipped with PTC thermistor sensors. Connect the PTC
thermistor sensors to the PTC thermistor tripping unit.
We recommend standby heating for motors which, due to climatic
conditions, are at risk of condensation (e.g. stationary motors in moist
atmospheres, or motors exposed to extreme variations in tempera-

Standby heating is used to protect the motor windings against con-
densation water inside the motor.
