Siemens 1LA8 Operating Instructions

5.2.7 Draining condensation
Under the following conditions it is possible that condensation may accumulate within the
machine:
● Wide fluctuations in the ambient temperature, such as direct sunlight 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 within the machine.
Ensure that condensate can drain away.
Ensure that condensate can drain away
In the bearing shields on the DE and NDE, water drainage holes are situated below or opposite
the regreasing devices. They are sealed with screw plugs. Depending on the type of
installation, the water drainage holes are located at the bottom.

1. Regularly remove the screw plugs to allow the condensate to drain away.
2. Replace them when you have finished.
NOTICE
The degree of protection is reduced
Nominally the degree of protection of the machine is reduced to IP44 when the screw plug is
removed.
