As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
● Can the machine be put into operation?
● Must the windings be cleaned or dried?
Detailed information on testing and the limit values can be found here:
"Testing the insulation resistance and polarization index" (Page 41)
8.7 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.

8.8 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.
