Service and inspection intervals
General
Carry out maintenance work, inspections and revisions at regular intervals in order to be able
to identify faults at an early stage and remove them.
Note
Inspection if there are faults or unusual conditions
Unusual conditions o
r faults that place undue stress on a three-phase motor - e.g. overload,
-circuit - can cause consequential damage to the machine.
Immediately perform an inspection when faults or exceptional conditions occur.
Maintenance measures, inspection/maintenance times intervals
The maintenance intervals depend on the operating conditions.
● Adapt the maintenance intervals to match the local conditions, such as pollution/dirt,
switching frequency, load, etc.
Service and maintenance must only be performed by properly authorized qualified
personnel.
Only use original SIEMENS parts.
Siemens Service Centers distributed around the globe can maintain and repair the motor. To
do this, contact your local Siemens representative.
● Perform the following maintenance measures as listed in the table.
