Preparations for use
4.11 Transport and storage
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.
The materials used are specially designed for the temperature range required by the
customer. Do not store the motor in conditions that lie outside the specified temperature limits.
The relevant temperature limits are specified on the rating plate.
Long-term storage
If you are storing a machine for more than six months, you must check its condition every six
months. Store the machine in accordance with the specifications in Section "Storage
(Page 36)", and if possible, packed.
● Check the motor for damage.
● Carry out any necessary maintenance work.
● Make sure that the storage conditions are such that condensation cannot form in the motor.
● If the machine is not sealed in plastic film, continually and slightly heat the machine, e.g.
Storage for longer than three months
Lubricate the machine after every two years of storage.
1. Unpack the machine.
2. Remove the rotor shipping brace, if one is being used.
3. When stored for longer than two years, lubricate with twice the grease quantity in

WARNING
with anti-condensation heating (if available), and ensure that the air circulates in the storage
room.
accordance with the lubricant plate. This ensures that the grease is evenly distributed and
covers all surfaces. Corrosion damage is avoided.
NOTICE
Damage to roller bearings
Roller bearings can be damaged when kept in the same or almost the same position.
Every three months, manually rotate the rotor through five revolutions. Make sure that the
resting position of the roller bearings after the rotor has been turned is different from what
it previously had been. Use the feather key as a reference point, if present.
