Connecting the machine for a specific direction of rotation

If the machine has one shaft extension or two shaft extensions with different diameters, the
direction of rotation when looking at the front of the single or the thicker shaft extension is
defined as follows:
● If you connect the power cables in the phase sequence L1, L2, L3 to U, V, W, the resulting
● If you interchange two connections, e.g. L1, L2, L3 to W, V, U, the resulting rotation will be
● On machines which are only allowed to run in one direction, the rating plate shows an arrow
NOTICE
Incorrect direction of rotation
The machine will not be adequately cooled if it is operated other than how it was originally
ordered or with the incorrect direction of rotation. This can result in machine damage.
Observe the direction of rotation data on the nameplate.
