4.2.2. Motor connection / Winding protection / Separately driven fan
• The electrical connection of the motor, the separetely driven fan and the winding sensors to the mains is
made in the motor terminal box.
• The motor cable must be shielded. Ensure that the cable shield contacts the frame over a large area at both ends.
• The motor phases U1, V1 and W1 must be connected correctly to the corresponding phases of the inverter;
they must not be interchanged.
• We recommend using a inverter with a switching frequency of 8 kHz.
• The thermocouples installed in the winding such as PTC thermistor detectors and thermostatic switches must
be evaluated in the control system or frequency inverter to protect the motor from overtemperature.
• The separately driven fan must be properly connected and operated. If required, it can be switched in
dependence of the temperature by means of thermal switch S4 (relay must be used).
