5.3.2. Motor connection / Winding protection / Fan
•
The electrical connection of the motor, the fan and the winding sensors is made in the motor terminal box on the
machine.
• 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).
