•
Store the electric machine always indoors with the storage temperature above -20 ºC and the relative
humidity less than 60 %.
•
The storage should be dry, dust free and vibration free.
•
Treat the unprotected electric machine surfaces such as the shaft-end and flanges against corrosion.
Seal the cable exit holes and cooling bores for storage.
•
The electric machine must not be subject to any external vibrations during storage to avoid damage
to the bearings.
•
Use anti-condensation heaters, if fitted, or direct winding heating to avoid water condensing in the
electric machine.
•
Rotate the shaft of the electric machine by hand monthly at least ten revolutions to prevent grease
migration. If necessary, use a tool, for example a spanner. Do not damage the shaft in any case.
