8.1.2
Avoidance of damage to rolling bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the rotor in the rolling bearings can result in
damage, such as brinelling or corrosion.
● During stoppages, regularly start up the machine for a brief period once a month. As a minimum, turn the rotor several
times.
If you have uncoupled the machine from the driven machine and secured the rotor with a rotor shipping brace, then
remove this before turning the rotor over or starting up the machine.
Make sure that the resting position of the rotor after the rotor has been turned over is different from its previous position.
Use the fitted key or the coupling halves as reference markers.
● During recommissioning, refer to the information in Chapter "Commissioning".

8.1.3
Decommissioning the machine
● Record the decommissioning steps. This log will be useful upon recommissioning.
● If the machine is going to be out of service for longer than six months, then take the necessary measures for
preservation and storage. Otherwise, the machine could be damaged as a result of not being operated.
8.1.4
Re-commissioning the machine
When you re-commission the machine, proceed as follows:
● Study the record made when the machine was decommissioned, and reverse the measures that were taken for
conservation and storage.
● Perform the measures listed in the "Commissioning" section.

Safety instructions for inspection and maintenance
WARNING
Rotating and live parts
Electric machines contain live and rotating parts. Fatal or serious injuries and substantial material damage can occur if
maintenance work is performed on the machine when it is not stopped or not de-energized.
Perform maintenance work on the machine only when it is stopped. The only operation permissible while the machine
•
is rotating is regreasing the rolling bearings.
When performing maintenance work, comply with the five safety rules.
