If you are storing a machine for more than six months, you must check its condition every six
months.
● Check the machine for damage.
● Carry out any necessary maintenance work.
● Document all preservation measures taken so that they can be reversed before the
● Provide air-conditioning for the storage room.
Condensation
Condensation can collect in the machine as a result of sharp fluctuations in ambient
temperature, exposure to direct sunlight, high levels of humidity in the storage location or
intermittent operation/variations in load during operation.
CAUTION
Damage caused by condensation
If the stator winding is damp, its insulation resistance is reduced. This results in voltage
flashovers that can destroy the winding. Condensation can also cause rusting inside the
machine.
