Maintenance intervals

General
Regularly carry out maintenance work, inspections and revisions/overhauls in order to
identify and resolve faults at an early stage - before these result in subsequent damage.
Faults or unusual conditions
Faults or unusual conditions when operating the motor can result in death, severe injury or
material damage.
Electrical or mechanical stress placed on the three-phase motor, such as overload, short
circuit, etc. can damage it. This includes, short-circuit or overload, for example.
• Immediately perform an inspection when faults or exceptional conditions occur.
Operating conditions, maintenance intervals
Only general maintenance intervals can be specified here as a result of the different
operating situations.
● Maintenance intervals should, therefore, be scheduled to suit the local conditions
(pollution/dirt, switching frequency, load, etc.).
● Perform the following measures after the appropriate operating times or at the specified
intervals.
