Maintenance intervals

General
Careful and regular maintenance, inspections and overhauls are essential for
detecting and eliminating faults in good time before they can lead to extensive
damage.
Operating conditions and characteristics can vary widely. For this reason, only
general maintenance intervals can be specified here. For this reason, schedule the
maintenance intervals to suit the local conditions (dirt, starting frequency, load,
etc.).
Notice
In the event of faults or extraordinary conditions that lead to the three-phase motor
being overloaded either electrically or mechanically (e.g. overload, short circuit,
etc.), carry out the inspections immediately.
