The connection must be made in such a way that a permanently secure electrical connection is
maintained (no protruding wire ends). Suitable cable lugs must be used for the connections of all
main cables. A safe protective conductor connection must be made. Tightening torques can be
found in Table 2.

There must be no foreign bodies, dirt, or moisture in the terminal box. Close unused cable entry
openings and the terminal box so that they are dust- and watertight. For the test run without drive
elements, secure the feather key against being thrown out.
5.2.
Connection of lead out cables
For motors with lead out cables, the terminal board is dismantled at the factory and the connecting
leads are connected to the terminals of the stator winding. The connection leads are colour-coded,
the assignment of the colour is glued on the cover plate.
For the motor version with terminal box,
each individual wire is labeled. The user connects the lead out cables in the control cabinet
accordingly.
6. Commissioning
6.1.
General information
The installation must be carried out in a power-supply-free state, in accordance with applicable
regulations by appropriately trained personnel. The nameplate date of the motor must be compared
to the power supply conditions. The dimensions of the power cables must be adapted to the nominal
currents of the motor. The motors are to be operated with an overcurrent protection, which is
adjusted according to the rated data (1.1 times rated current) of the motor. Failure to do so leads to
the winding defect and a loss of warranty.
Please check the insulation resistance of the winding before switching it on for the first time. The
resistance should be higher than 5MΩ at an ambient temperature of 25°C. After longer storage, the
insulation test must also be carried out. Before the machine is connected, the direction of rotation
Caution:
ensure the appropriate
selection of the power supply cables.
Caution: check the insulation
resistance of the winding before
commissioning.
