Installation and Assembly
strip, for example, or pinned. Where a belt power take-off is used, mount the motor
on sliding rails so as to be able to set the correct belt tension.
Caution
If the belt tension is too high, the bearings and shaft are at risk. It is essential to
adhere to the permissible values in accordance with the manufacturer's
specifications.

Instructions relevant for safety
General
Connecting
Danger
All work on the motor at rest must always be carried out by qualified expert
personnel with the motor in the disconnected state and secured to prevent
restarting.
Check safe isolation from the supply.
The connection to the supply is made in the terminal box. Additional terminals are
available for auxiliary circuits, with terminal strips for conductor cross-sections of up
to 2.5 mm 2 .
Depending on the type of construction, terminal post insulators or terminal boards
are installed for connection of the excitation.
The terminal boxes can be rotated through increments of 90° corresponding to the
connection direction. In this case it must be ensured that the winding conductors
are correctly rerouted. The arrangement of the insulating plate does not need to be
changed. In unfavorable circumstances, for example given large cross-sections
and a large number of conductors, the possibility of repositioning is partly restricted
or requires special adaptive measures.
It must be ensured that a permanent, safe electrical connection is retained.
Use the assigned cable end components.
