Risk of death due to electric shock!
During and immediately after the measurement, in some instances, the terminals are at
hazardous voltage levels, which can result in death if touched.
• Never touch the terminals during or immediately after measurement.

Maintenance
Carrying out maintenance work at the machine
Note
It is essential that you observe the safety instructions provided in this documentation.
As a result of their inherent principle of operation, the motors are always wear-free. To
ensure that the motor functions properly and remains free of wear, the following
maintenance work needs to be carried out:
● Regularly check that the rotary axis is free to rotate.
● Regularly check that the minimum air gap between the stator and rotor is as specified.
● Ensure perfect operation and that the power losses are adequately dissipated.
– Keep the air gap free of metal chips and particles.
– Keep pollution and dirt away from the motor space, e.g. metal chips and oil.
● Regularly check the general state of the machine.
● Check the current drawn in the previously defined test cycle.
● Check the cables to ensure that they are not damaged and are not worn. Never use
electrical devices and equipment with damaged cables.
● Make sure that the cable glands are secure.
Intervals between maintenance
Since operating conditions differ greatly, it is not possible to specify intervals between
maintenance work.
