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.
NOTICE
Insulated roller bearings
If insulated roller bearings are installed, use insulated roller bearings of the same type as
spare part. This will prevent any bearing damage being caused by bearing currents.
10.3 Anti-condensation heating
Risk of explosion
If repairs to the anti-condensation heating are not carried out correctly, e.g. if unauthorized
or untested spare parts are used, this can result in explosions during operation in a potentially
explosive gaseous atmosphere. This can result in death, serious injury or material
damage.
Repairing and mounting the anti-condensation heating and the subsequent routine testing
must always be undertaken by experts from the Service Center (Page 149), because this
work requires extensive specialist knowledge. Only authorized and tested spare parts may
be used.
