2.7 Routine maintenance of frequency convertor
2.7.1 Routine maintenance
The influence of environment temperature, humidity, dust and vibration will lead to aging of internal
components and potential fault, or reduce lifespan of frequency convertor, so it's necessary to conduct routine
and regular maintenance.
Routine inspection items:
1) If any abnormal change of sound during motor operation
2) If any vibration during motor operation
3) If any change of installing environment for frequency convertor
4) If normal work of cooling fan for frequency convertor
5) If overheating of frequency convertor
2.7.2 Regular inspection
Regular inspection items:
1) Inspect air channel and clean regularly
2) Inspect if any loosening of screw
3) Inspect if any arc trace of wiring terminal
