Drain condensation
Depending on the mounting position, the condensation drain holes are always at the
bottom of the motor!
¯
For condensate drainage
–
the motor must be deenergised;
–
the plugs (screws) must be removed.
Stop!
To restore the enclosure, re−insert the plugs (screws) after condensate
drainage. If the condensation drain holes are not sealed again, the IP
enclosure of the motor will be reduced. For horinzontal motor shafts to
IP23 and for vertical motor shafts to IP20.
