Working on the electric motor:
Work must not be carried out on the electric motor until the motor has come to a
standstill, is electrically isolated, de-pressurized and has cooled down. All
connections, such as screws on the motor that were loosened must be tightened
again after the inspection and maintenance work.
When carrying out work on the motor, please observe the technical instructions and
notes in the respective sections in these Commissioning and Maintenance
Instructions.
When carrying out maintenance work, observe all safety instructions which also apply
to the commissioning of the motor (see Section 5.1).

If the optional holding brake is fitted, this brake must not perform a safety function
during work on the motor (e. g., retaining loads)!
