Disassembly
DANGER
⇒ Work on machines is only allowed if they are secured and while they are
not running.
⇒ Before starting disassembly, secure the machine against unforeseeable
movements and against unauthorized operation.
⇒ Before dismounting the motor and the supply lines, secure them against
dropping or moving and disconnect the mechanical connections only there‐
after.
The machine manufacturer must observe the special features of
the construction and create a special disassembly instruction for
the motor components rotor and stator. Only this disassembly in‐
struction of the machine manufacturer is binding.
1. Observe the disassembly instruction of the machine manufacturer.
2. Use the machine-side control command to decelerate the drive to a con‐
trolled standstill.
3. Switch off the power and control voltage of the controller.
4. Switch off the main switch of the machine and deactivate external sys‐
tems according to the instructions of the manufacturer.
5. Secure the machine against accidental movements and against unau‐
thorized operation.
6. Wait until the discharge time of the electrical systems has elapsed and
then disconnect all electrical connections. Lock electric cables and con‐
tacts against contact with other electrical parts.
7. Remove dirt, chips and other any kind of residues from the motor.
8. Before disassembling the motor and the supply lines, secure them
against dropping or movements. Subsequently, disconnect the mechani‐
cal connections.
9. Empty the coolant ducts of the motor and dismount the motor from the
machine. Store the motor appropriately.
10. If necessary, record all measures in the commissioning log or machine
maintenance plan.
Fatal injury due to errors during the activation
of motors or work on moving elements!
