WARNING
Risk of death and crushing as a result of permanent magnet elds
Severe injury and material damage can result if you do not take into consideration the safety
instructions relating to permanent magnet elds.
• Refer to Chapter "Danger from strong magnetic elds (Page28)".
10.1 Decommissioning
Sequence when decommissioning and disassembling the motor
WARNING
Risk of injury and material damage
Injury and/or destruction of motor components can occur if you do not observe the specied
sequence when decommissioning and disassembling the motor.
• Perform decommissioning and disassembly work in the specied sequence only.
Procedure
1. Bring the motor into a no-voltage condition. Wait until the DC link of the power unit has been
discharged.
2. Allow the motor to cool down for at least 30min.
3. Switch o the cooling. Reduce the pressure to 0bar.
4. Disconnect the power and signal cables and the coolant pipes.
5. Insulate uncovered power connections.
6. Drain the coolant from the motor and dispose of it correctly.
7. Remove chips, dirt, foreign particles, etc. from the motor.
8. Insert the spacer lm between the stator and rotor.
9. Screw on the transport locks at the opposite end of the motor to the mounting end. If the
stator and rotor come into contact with each other, these two components can be separated
again only with considerable eort. The reason for this is the extremely high magnetic
attractive forces which they exert.
