NOTICE
Damage to insulation
If metal swarf enters the winding head when cleaning with compressed air, this can
damage the insulation. Clearance and creepage distances can be undershot. This may
cause damage to the machine extending to total failure.
When cleaning with compressed air, ensure there is adequate extraction.
NOTICE
Machine damage caused by foreign bodies
Foreign bodies such as dirt, tools or loose components, such as screws etc., can be left by
accident inside the machine after maintenance is performed. These can cause short
circuits, reduce the performance of the cooling system or increase noise in operation. They
can also damage the machine.
•
When carrying out maintenance work, make sure that no foreign bodies are left in or on
the machine.
•
Securely attach all loose parts again once you have completed the maintenance
procedures.
•
Carefully remove any dirt.
Note
Operating conditions and characteristics can vary widely. For this reason, only general
intervals for inspection and maintenance measures can be specified here.
9.2.2
Explosion hazard due to increased surface temperature
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.
