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 Inspections in the event of faults
Natural disasters or unusual operating conditions, such as overloading or short circuit, are
faults that overload the machine electrically or mechanically.
Immediately perform an inspection after such faults.
Note
Pay particular attention to the relubrication intervals for rolling bearings that deviate from the
inspection intervals.
Note
When servicing a three-phase machine, it is generally not necessary to dismantle it. The
machine only has to be dismantled if the bearings are to be replaced.
