Note
Cleaning and/or drying the windings when reaching critical insulation resistance
If the critical insulation resistance is less than or equal to this value, the windings must be
dried or, if the fan is removed, cleaned thoroughly and dried.
Note that the insulation resistance of dried, clean windings is lower than that of warm
windings. The insulation resistance can only be evaluated accurately when measured on a
winding that has been cooled down to room temperature (approximately 20 °C to 30 °C).
Note
Measured value close to critical value
If the measured value is close to the critical value, the insulation resistance should be
subsequently checked at suitably regular intervals.
Values apply for measurement at a winding temperature of 25 °C.
8.4
Switching on and switching off
Note
EMERGENCY OFF
To avoid accidents, be familiar to the EMERGENCY OFF function before you switch on the
system.
The motor is switched on and off using the converter. Read about this topic in the converter
operating instructions.
Prerequisites
• Ensure that the converter is correctly parameterized.
• Use the appropriate commissioning tools.
Switching on
1. Switch on the motor by the converter.
2. Ensure smooth motor operation.
3. Check the function of the motor cooling system.
4. Check the function of the safety equipment.
5. Check whether the motor reaches the required parameters.
Switching off
1. Switch off the motor by the converter.
After you complete the operation, the motor has been commissioned.
