Risk of explosion due to damaged sealing materials
Storing the machine at temperatures that do not fall within the specified limits can damage
the material of the seals and cause them to fail. As a result, a potentially explosive gaseous
atmosphere can enter the machine and be ignited during commissioning. Explosions can
occur. This can result in death, serious injury or material damage.
• Do not store the machine in conditions that lie outside the specified temperature limits.
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines 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 machine 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.
