● Wide fluctuations in the ambient temperature, such as direct sunshine combined with high
● Intermittent operation or load fluctuations during operation
Depending on the type of installation, the water drainage holes are located at the bottom:
Allow the condensation water to discharge for vertical placement

NOTICE
Damage due to condensate
If the stator winding is damp, its insulation resistance will be reduced. This can result in
voltage flashovers, which can destroy the winding. Condensate can also cause rust to form
within the machine.
Ensure that condensate can drain away.
