Horizontal lifting
Install 2 pieces of lifting eyes to the lifting bores of the electric machine frame. Mount the lifting eyes with
their full threaded length.
Vertical lifting
Install 2 pieces of lifting eyes to the lifting bores in the N-end SAE flange. Lifting eye should be mounted
with its full threaded length.
Storage
Do not touch the electrical terminals when the shaft is rotated. The electrical terminals have
dangerous voltage during rotation.
Keep the electric machine on a correct base. Support the electric machine to prevent
accidental turning and falling.
•
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.
Extended storage
Electric machines equipped with relubricable bearings: apply grease before and after long term storage.
It is recommended to inspect the electric machine in storage at periodic intervals. Use attached storage
checklist.
Rotate the shaft of the electric machine once a month.
Keep the electric machine in its installation position while in storage. For example, vertically installed
electric machines should be stored in vertical position.
