6.6 Connecting the motor in the terminal box
In the case of the converter world motor, do not change the star or delta connection. The
MLFB and the motor data contain information about the connection method.
Select the connection cables according to DIN VDE 0100. Take into account the rated current
and the plant-specific conditions. Shielded cables are used for motors that are operated with
a converter.
The following required information for connection is specified in the technical data:
• Direction of rotation
• Number and arrangement of the connections
• Circuit / connection of the motor winding.
Note
High starting currents occur when starting three-phase motors connected directly to the line
supply Use the star-delta starting connection to reduce these. Comply with local regulations
when doing this. Alternatively, motors can be operated with a soft starter or a converter.
