Anti-condensation heating
Explosion hazard due to improper maintenance of the anti-condensation heating
If the anti-condensation heating is not correctly repaired, e.g. if unauthorized or untested
spare parts are used, this can result in explosions during operation in a potentially explosive
atmosphere. This can result in death, serious injury or material damage.
● Only appropriately trained specialists in the service center (Page 159) are authorized to
repair anti-condensation heating systems. The anti-condensation heating must then be
subject to a routine test, which requires extensive specialist knowledge.
● Only use authorized and tested spare parts.
Explosion hazard due to improper maintenance
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
• Only authorized and tested spare parts may be used.

Fundamentals
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.
If possible, assemble the machine on and alignment plate. This ensures that the mounting
feet surfaces are all on the same plane.
Avoid damaging the windings protruding out of the stator enclosure when assembling the
end shield.
Sealing measures
1. For 1MB10, shaft heights 100...160, apply the appropriate liquid sealant, e.g. Fluid-D or
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.

WARNING
testing must always be undertaken by experts from the service center (Page 159),
because this work requires extensive specialist knowledge.
