5.1 Safety notes
Working on the electric motor:
Perform all works on the electric motor only when the motor is standing still, is deener-
gized and is cooled down. All connections loosened during the work on the electric
motor such as screws etc. must be tightened before commissioning.
When carrying out the work it is essential to observe the technical notes in the reqpec-
tive chapters of this eommissioning and maintenance manual.
Attention!
If the holding brake is installed as an option, it must not take any safety function during
work on the motor (e.g. holding loads).
Danger to life from electric current:
Make sure that the electric motor is disconnected and without voltage.
Never disconnect the connections on the motor during operation.
Only connect measuring instruments when they are currentless and de-energized.
Do not start work on the motor connections until you have ensured that neither poten-
tial nor voltage is present.
During operation, electrical potential is present at the motor contacts and at the motor
windings. Never touch these components/elements during operation.
Assembly and disassembly of safety devices
The electric motor must not be operated without mounted safety devices.
For the assembly and disassembly of components and systems intended to monitor
safe motor operation, the motor must be taken out of operation
Danger of contact:
Make sure that the electric motor is stationary and protected against being switched on
again before touching it.
Touch the output shaft only when the motor is not energized and stopped. Otherwise,
there is a danger from the rotating rotors
Risk of burns!
Never touch the motor housing during rated load operation. Surface
temperatures of
over 70 °C
can occur on the motors.
5.2 Tests before commissioning
The drive is undamaged and is not in the danger zone of other equipment.
The motor is properly aligned and secured. Screw connections are correctly tightened.
All associated protective devices (mechanical, thermal, electrical) are mounted.
The motor connections are properly made.
The cables do not touch the motor surface.
- The protective conductor system is correctly implemented and tested for function
- The drive does not block (release brake, if present).
- Emergency stop functions are checked.
- The fan is properly connected, the functionality has been checked.
