Preparing for use
4.5 Transport and storage
4.5.3
Temperature limits during storage
The materials used are specially designed for the temperature range required by the customer.
The relevant temperature limits are specified on the rating plate.
Risk of explosion due to damaged sealing materials
Storing machines at temperatures that do not fall within the specified limits can damage the
material of the seals and cause them to no longer seal correctly. The certified type of protection
of the machine can no longer be complied with.
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.

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.

WARNING
Do not store the machine in conditions that lie outside the specified temperature limits.
