10.4 Anti-condensation heating

Rolling-contact bearings
When ordering roller 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.
If roller-contact bearings with an insulated design are installed, use roller bearings of the same
type as spare parts. This will prevent any bearing damage being caused by bearing currents.
10.4 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 137) specialists.
