6.4.4 Rotating the terminal box (option)
Optionally, depending on the terminal box and version, you can rotate the terminal box through
±90° in accordance with the connection direction. Switching over to the other motor side is only
possible with support from the Service Center (Page 153).
Rotating the terminal box
If necessary, remove the internal stator cables.
1. Ensure that the motor is disconnected from the power supply.
2. Release two diagonally opposed screws for the cover, and secure the cover using two
threaded bars screwed in diagonally opposing one another.
Release the two other screws and lift the cover off the terminal box. The terminal box cover
is very heavy. Especially when in a lateral position, ensure that the terminal box does not fall
down.
3. If the motor is already connected:
– Remove the cables of the power supply.
– Release the screw connection of the cable entry. Remove the cables through the
opening.
4. Release the screwed connections of the internal stator cables.
5. Release the screwed connections of the lower section with the console; if present, release
the high-frequency grounding to the motor enclosure.
6. Screw in two eye-bolts diagonally in the thread at the corners. Slightly raise the terminal box
housing using a crane.
7. Rotate the terminal box through ±90° in the desired direction. Carefully place the terminal
box down. Take care not to damage the seal.
8. Screw the terminal box to the console (4 x M16, tightening torque 170 Nm).
9. If present: Reconnect the high-frequency grounding.
10.Connect the cables in accordance with the circuit diagram on the inside of the cover. Ensure
that the minimum air clearances are observed. More on this (Page 81)
11.Reconnect the power supply cables. More information:
