Preparing for use
4.5 Transport and storage
Bare metal surfaces
For transport, the bare surfaces (shaft extensions, flange surfaces, centering edges) should
be coated with an anti-corrosion agent which will last for a limited amount of time (<6
months). Apply suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the
environmental conditions, every six months at the latest.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For motors that have a special design regarding the ambient temperature in the operating
state or the installation altitude, other conditions could apply regarding the storage
temperature. In this case, refer to the motor rating plate for data on the ambient temperature
and installation altitude.
Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce
the useful life of the bearing grease (aging).
Open bearings
• For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12
months.
• Replace the grease if it is identified that the grease has lost its lubricating properties or is
polluted. The consistency of the grease will change if condensation is allowed to enter.
Closed bearings
• For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.
NOTICE
Storage
The motor can be damaged if you use it or store it unprotected outdoors.
• Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a
• If required, contact the service center, or technically coordinate outdoors use.
