Electrical voltages are induced when the rotor is rotated

Danger due to induced voltages
Electrical voltages are induced in the stator when rotating the rotor. Touching the stator
connections can result in death or severe injury.
• Before starting any work at the machine, carefully ensure that the system is secured to
prevent the rotor accidentally turning in compliance with the regulations.
• If you must rotate the rotor, then ensure that each phase is grounded.
Loss of conformity with European directives
In the delivery state, the machine corresponds to the requirements of the European directives.
Unauthorized changes or modifications to the machine lead to the loss of conformity with
European Directives and the loss of the associated warranty.
5.3 Preparing for installation
5.3.1

Requirements for installation

The following requirements must be satisfied prior to starting installation work:
• Staff have access to the operating and installation instructions.
• The machine is unpacked and ready for mounting at the installation location.
• Measure the insulation resistance of the winding before starting any installation work. If the
insulation resistance lies below the specified value, take appropriate remedial measures.
These remedial measures may necessitate the machine being removed again and
transported.
Note
Note also the technical data on the rating plates on the motor enclosure.
NOTICE
Damage to the motor
To avoid material damage, before commissioning, check whether the correct direction of
rotation of the machine has been set on the customer side, e.g. by decoupling from the driven
load.
