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.
9.8 Corrective maintenance
9.8.1 Reference to chapter Safety instructions
When carrying out any work on the machine, observe the general safety instructions
(Page 13) and the specifications contained in EN 50110-1 regarding safe operation of
electrical equipment.
9.8.2 Storage
9.8.2.1 Bearings
Refer to the rating plate or the catalog for the designations of the bearings being used.
Bearing lifetime
Prolonged storage periods reduce the useful lifetime of the bearing grease. For permanently
lubricated bearings, this reduces the bearing service life.
We recommend that the bearings or grease are replaced after a storage time of 12 months;
if the time exceeds 4 years, replace the bearings or the grease.
