Maintenance intervals
Please note the following in order to identify faults at an early stage, rectify them and avoid
follow-on damage:
•
Maintain the motor regularly and carefully.
•
Inspect the motor.
•
Motors must be allocated a revision/inspection number after inspection.
NOTICE
Motor failure
Material damage can occur if the motor develops faults or is overloaded.
•
Immediately inspect the motor if faults occur.
•
An immediate inspection is especially necessary, if the three-phase motor is
excessively stressed, either electrically or mechanically (e.g. overload or short-circuit).
The motors are equipped with permanently lubricated rolling bearings. The motor may be
equipped with a regreasing device.
CAUTION
Skin irritations and eye inflammations
Many greases can cause skin irritations and eye inflammations.
•
Follow all safety instructions of the manufacturer.
Measures, intervals and deadlines
Measures after operating period intervals or deadlines have elapsed:
Operating situations and characteristics can vary widely. For this reason, only general
maintenance intervals are specified here. Maintenance intervals should therefore be
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).
