Maintenance
9.3 Corrective maintenance
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.
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.
