9.2 Corrective Maintenance
Observe the following when carrying out any work on the machine:
● Comply with the general safety instructions (Page 13)
● Comply with the applicable national and sector-specific regulations at the place of
installation
● When using the machine within the European Union, comply with the specifications laid
down in EN 50110‑1 regarding safe operation of electrical equipment.
If the motor has to be transported, please observe the information and instructions in the
chapter "Transport (Page 27)".
9.2.1 Prepare servicing work
● The drawings and parts lists do not contain any detailed information about the type and
dimensions of fixing elements and components. For this reason, you should establish this
information when dismantling them and make a note of it for the purpose of reassembly.
● Document the type, dimensions and arrangement of the parts so that you will be able to
reassemble the machine to its original state.
● Use suitable tools to disassemble the machine.
● Take measures to prevent parts from dropping down before you dismantle them, e.g. by
replacing fastening elements with extra-long screws, threaded bolts or similar. This ensures
that the part is supported after it is pulled off.
● The centerings in the shaft extensions have reset threads. Use lifting gear which is suitable
for the rotor weight and direction of loading.
Danger when a rotor falls
Eyebolts in accordance with DIN 580 are unsuitable for suspending the rotor. The rotor can
fall off. This can result in death, serious injury or material damage.
● Use lifting gear which is suitable for the rotor weight and direction of loading.
Machine damage caused by improper repair work
Improper servicing work can damage the machine. This can cause damages and/or faults
which can result in eventual or immediate death, serious injury, or property damage.
● Properly assemble or disassemble the machine.
● Use only suitable tools and equipment.
● Immediately replace damaged components.
● Contact the Service Center (Page 121), if necessary.
