10.4 Purchasing commercially available spare parts
Explosion hazard due to unsuitable spare parts
If you use parts other than the original spare parts, the type of protection can no longer be
guaranteed. This can result in an explosion during operation in a potentially explosive
atmosphere. This can result in death, serious injury, or material damage.
• Use only original spare parts for explosion-proof machines, including components, such
as seals, terminals, cables, and cable entries. If you have any questions, please contact
the service center (Page 159).
• Commercially available equivalent standard parts such as screws and bolts may be
used.

10.6 Replacing rolling bearings
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.
