5.4.7 Draining condensate
Under the following conditions it is possible that condensate may accumulate in the machine:
● Wide fluctuations in the ambient temperature, such as direct sunshine combined with high
atmospheric humidity
● Intermittent operation or load fluctuations during operation
NOTICE
Damage due to condensate
If the stator winding is damp, its insulation resistance will be reduced. This can result in
voltage flashovers that can seriously damage the windings. Condensate can also cause
rust to form in the machine.
Ensure that condensate can drain away.
Ensure that condensate can drain away
In the end shields or in the casing at the drive end and non-drive end, water drainage holes
are situated lower down and opposite the regreasing devices. They are sealed with screw
plugs and retaining washers.
● Regularly remove the screw plugs to allow the condensate to drain away.
● Then re-fit the screw plugs and lock washers, so that the machine's degree of protection
is ensured.
Drainage plugs which allow the water to drain away automatically can also be fitted. Depending
on the type of installation, the water drainage holes are located at the bottom.
● Regularly check the drainage plugs. The water must be able to drain away freely.
NOTICE
The degree of protection is reduced
The degree of protection of the machine is nominally reduced to IP44 when a plug or screw
is removed.
