• If you connect line cables with a phase sequence of L1, L2, L3 at U, V, W,
the resulting rotation is clockwise.
• If you interchange two connections, e.g. you connect L1, L2, L3 to V, U, W,
the resulting rotation will be counter-clockwise.

The number and size of the cable entry tapped holes is provided in the
machine dimension drawing.
Inserting cables into the terminal box
1. The machine is equipped with cylindrical sealing ring terminals on the
terminal box. Use only adapted cylindrical sealing rings that are suitable for
the cables.
2. Only use suitable cylindrical sealing rings and cables for the prevailing
ambient temperature.
3. Ensure that the power cables are strain relieved when inserting them in the
terminal box.
4. Carefully connect the cables and ensure a reliable protective conductor
connection.
5. Tighten the two screws for the cylindrical sealing rings to the torques
specified by the manufacturer.
6. Tighten the two screws for the clamping plates to the torques specified by
the manufacturer to provide strain relief for the cables.
7. Check the cylindrical sealing rings and cables to ensure that they are
correctly sealed and secured in place.
8. Correctly close and seal threads or holes that are not being used ensuring
that the IP degree of protection is maintained. The IP degree of protection is
specified on the rating plate.
