Terminal marking

For terminal designations, the following principle definitions apply to three-phase motors:

Direction of rotation

The motors are suitable for clockwise and counter-clockwise rotation.
When the line feeder cables are connected in the phase sequence L1, L2, L3 to U, V, W, the
motor rotates clockwise when looking at the drive end of the shaft extension (DE). If two of
the connections are swapped, the resulting direction of rotation is counter-clockwise,
e.g. L1, L2, L3 to V, U, W.
