generate error action.
The solution is to reduce the carrier frequency or install output reactor. It is recommended that thermal relay not
be installed before the motor when using the inverter, and that electronic over current protection function of the
inverter be used instead.
6.3.6 Precautions for Installing EMC input filter at the input end of power supply
1)
When using the inverter, please follow its rated values strictly. Since the filter belongs to Classification I
electric appliances, the metal enclosure of the filter shall be large and the metal ground of the installing cabinet
shall be well earthed and have good conduction continuity. Otherwise there may be danger of electric shock
and the EMC effect may be greatly affected.
2)
Through the EMC test, it is found that the filter ground must be connected with the PE end of the inverter at
the same public earth. Otherwise the EMC effect may be greatly affected.
3)
The filter shall be installed at a place close to the input end of the power supply as much as possible.
