10.3 Anti-condensation heating
NOTICE
Rotor removal or bearing change
Improper handling can lead to irreparable damage to the motor.
If it is necessary to remove the rotor or change the bearings, then under all circumstances
please contact the Service Center (Page 117).
Rolling bearings
When ordering rolling bearings, in addition to the bearing identification code, the
supplementary specifying code is also necessary for the bearing version. Both of these codes
are stamped on the lubricant plate and specified in the motor documentation, or can also be
taken from the installed bearings.
Always replace the rolling bearings with the identical bearings.
If insulated rolling bearings are fitted, use insulated rolling bearings of the same type as spare
parts. This will prevent any bearing damage being caused by bearing currents.
10.3
Anti-condensation heating
The anti-condensation heater is mounted directly on the winding. The anti-condensation heater
cannot be removed without causing damage to the winding. A new anti-condensation heater
may only be installed by Siemens Service Center (Page 117) specialists.
