Position of the connections
For the position of the connections, see the layout diagrams.
1. Open the cabinet, remove the covers (if necessary) in front of the connection panel for
motor cables (terminals U2/T1, V2/T2, W2/T3; X2) and power cables (terminals U1/L1,
V1/L2, W1/L3; X1).
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 to the cable entry at the
appropriate positions and then introduce the cable from below so that a subsequent
sealing is not required.
