Drain Condensate - Siemens SIMOTICS SD Operating Instructions Manual

Cleaning the cooling air passages
Regularly clean the cooling air passages through which the ambient air flows, e.g. using dry
compressed air.
Note
Never direct compressed air in the direction of the shaft outlet or machine openings.
In the case of machines with textile fan covers, regularly remove fluff balls, fabric remnants,
and similar types of contamination (particularly at the air passage opening between the fan
cover and cooling fins of the machine enclosure) to ensure that the cooling air can flow
without obstruction.
Note
The frequency of the cleaning intervals depends on the local degree of contamination.
Damage to the motor
Material damage can occur if you direct compressed air towards the shaft outlet or
openings in the motor.
Avoid directly pointing compressed air onto shaft sealing rings or labyrinth seals of the
motor.

Drain condensate

If there are condensate drain holes present, these must be opened at regular intervals,
depending on climatic conditions.
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, all
of the drain holes must be closed again.
