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.
NOTICE
Damage due to 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.
Water drain holes (option L12)
Depending on the order concerned, the bearing shields at the DE and NDE are equipped with
water drainage holes in the foot area and opposite the regreasing system. Make sure that the
condensation can always drain away freely.
● Shaft heights 180 and 225: The plug that has been inserted into the water drainage holes
allows the condensation to drain away. Do not remove the plug, otherwise the machine's
degree of protection will be affected.
● Shaft height 280: There are no plugs in the water drain holes. The water must be able to
drain away freely.
NOTICE
Water drain holes
The water drain holes only function when the motor is mounted horizontally for types of
construction IM B3, IM B35 and IM B5.
