WARNING
Explosion hazard due to increased surface temperature
Components within the motor may be hotter than the maximum permissible surface
temperature for the enclosure. In an explosive atmosphere, dust can ignite and an explosion
occur. This can result in death, serious injury or material damage.
● Do not open the motor in an explosive and dusty atmosphere when it is still at normal
operating temperature.
● Allow the machine to cool down before opening it.
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 153) 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.
9.3.1
Fundamentals
If possible, assemble the machine on and alignment plate. This ensures that the mounting feet
surfaces are all on the same plane.
● Position all rating and supplementary plates as in the original state.
● Where relevant, fix electric cables.
● Check the tightening torques of all screws, as well as those of screws that have not been
released.
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.
9.3.1.1
Screws with preCOTE coating
The motor can partly be fitted with screws with preCOTE coating. To ensure screw locking, use
new screws with preCOTE coating during assembly/repair. As an alternative, use normal
screws with a threadlocker such as Loctite.
