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 40)", 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.
