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 163). 
•  Commercially available equivalent standard parts such as screws and bolts may be 
used.

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.
