Direction of rotation
The standard motors are suitable for clockwise and counter-clockwise rotation.
For defined directions of rotation (direction of rotation arrow), appropriately connect the line
power cables.
• If you connect the line cables with phase sequence L1, L2, L3 at U, V, W or according to NEMA
at T1 T2 T3 , then the machine rotates in the clockwise direction.
• If you interchange 2 connections, e.g. L1, L2, L3 at V, U, W or according to NEMA at T2 T1 T3,
then the machine rotates counterclockwise.
