During transport and storage, condensation drain holes (see Fig. 1) are sealed<br />
with plugs to protect them from pollution. Remove the plugs prior to<br />
commissioning!<br />

Motor with condensation drain holes<br />
Condensation drain holes<br />
Note!<br />
ƒ Depending on the mounting position, the condensation drain holes are<br />
always at the bottom of the motor!<br />
ƒ For condensate drainage<br />
– the motor must be deenergised;<br />
– the plugs (screws) must be removed.<br />
Stop!<br />
To restore the enclosure, re−insert the plugs (screws) after condensate<br />
drainage. If the condensation drain holes are not sealed again, the IP enclosure<br />
of the motor will be reduced. For horinzontal motor shafts to IP23 and for<br />
vertical motor shafts to IP20.<br />
The required maintenance intervals strongly depend on the corresponding ambient and<br />
operating conditions. Initially, the condensation drain holes should be opened more<br />
frequently (at least once a week) to obtain experimental values for the condensate<br />
quantity arising.<br />
