Maintenance
9.3 Corrective maintenance
Servicing the separately driven fan motor
• Perform an occasional visual inspection of the separately driven fan motor and check it
electrically and mechanically every time the rolling bearings are replaced.
• Replace the permanently lubricated rolling bearing on the separately driven fan motor
after 40000 operating hours or five years at the latest.
9.3
Corrective maintenance
Observe the following when carrying out any work on the motor:
• Comply with the general safety instructions (Page 139).
• Comply with the applicable national and sector-specific regulations.
• When using the motor within the European Union, comply with the specifications laid
down in EN 50110-1 regarding safe operation of electrical equipment.
Risk of explosion as a result of inadmissible repair work
Repairs are only permissible within the scope of the work described in these operating
instructions. Otherwise an explosion can occur in an explosive atmosphere. This can result in
death, serious injury or material damage.
• For repairs to go beyond this scope, please contact the Service Center.
Note
Before commencing removal, you should mark how each of the fastening elements has been
assigned, as well as how internal connections are arranged. This simplifies subsequent
reassembly.
Avoid damaging the windings protruding out of the stator enclosure when assembling the
end shield.
If possible, assemble the motor on and alignment plate. This ensures that the mounting feet
surfaces are all on the same plane.
Sealing measures
1. Apply the necessary liquid sealant, e.g. Fluid-D, Hylomar, to the centering edge.
2. Check the terminal box seals, and if required, replace these.
3. Repair any damage to the paint, also to screws/bolts.
4. Take the necessary measures to ensure compliance with the applicable degree of protection.
5. Do not forget the foam rubber cover in the cable entry. Completely seal the holes, and
ensure that cables do not come into contact with sharp edges.
