6-3-6.Precautions on installing EMC input filter at the input end of
power supply
1) Note: 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 and the metal ground of the
installing cabinet shall be well earthed in a large area, and have good conduction continuity,
otherwise there may be danger of electric shock and the EMC effect may be greatly affected.
Through the EMC test, it is found that the filter ground end and the PE end of the inverter must be
connected to the same public earth end, otherwise the EMC effect may be greatly affected.
2) The filter shall be installed at a place close to the input end of the power supply as much as
possible.
