Decommissioning and disposal

Risk of death and crushing as a result of permanent magnet fields
Severe injury and material damage can result if you do not take into consideration the
safety instructions relating to permanent magnet fields.
• Refer to Chapter "Danger from strong magnetic fields (Page 24)".
9.1

Decommissioning

Sequence when decommissioning and disassembling the motor
Risk of injury and material damage
Injury and/or destruction of motor components can occur if you do not observe the specified
sequence when decommissioning and disassembling the motor.
• Comply with the specified sequence when decommissioning and carrying out
1. Disconnect the motor and wait until the DC link of the power unit has discharged.
2. Allow the motor to cool down.
3. Disconnect the power and signal cables.
4. If necessary, insulate the power connections properly (to prevent risk of electric shock
due to induced voltage and the short-circuit braking torques for a phase short-circuit).
5. Remove chips, dirt, foreign particles, etc. from the motor.
6. Insert the spacer foil between the stator and rotor.
7. Screw on the transport locks at the opposite end of the motor away from the mounting
end. As a result of the extremely high magnetic forces of attraction, when stators and
rotors come into contact with one another, it is extremely difficult to separate them with
high associated costs.
