WARNING
Hazardous voltage
The winding can be damaged if objects are introduced into the
condensation holes (optional). This can lead to death, serious injury or
material damage.
Note the following to maintain the degree of protection:
Switch off the machine so that it is in a no-voltage condition before
•
you open the condensation drain holes.
Close the condensation drain holes, e.g. using T-plugs, before
•
commissioning the machine.
NOTICE
Reduction of the degree of protection
If condensation drain holes are not closed, then this can result in material damage
to the motor.
In order to maintain the degree of protection, after the condensation has been
drained, you must close all of the drain holes.
