Connecting the motor cables
Note
Position of the connections
For the location of the connections, see the layout diagrams.
1. Open the cabinet and remove the covers in front of the connection panel for motor cables
(terminals U2/T1, V2/T2, W2/T3; X2).
2. Insert the cables through the elastic cable entry below the connection panel.
For example, you can use a knife to make a circular slit in the cable entry at the
appropriate positions and then introduce the cable from below so that subsequent sealing
is not required.
3. Screw the protective earth (PE) onto the PE busbar at the specified points in the cabinet
(50 Nm with M12).
