Connecting the grounding conductor
● Ensure that the connecting surface is bare and is protected against corrosion using a
● Locate the flat and spring washers under the bolt head.

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.

Introducing and routing the cables

6.4.1

Inserting the cable into the terminal box

The connection cables are inserted into the terminal box via an exchangeable cable entry
plate. The cable entry plate is not drilled by default. This enables you to adapt the number and
size of the boreholes to the rated conditions.
