5.4 - RFI filters
5.4.1 - General
The use of RFI filters contributes to
a reduction in the emission levels of
radio-frequency signals (see §4.6).
Depending on the drive used, install the RFI filter recommended
in the table below between the mains and the drive input.
The cable length does not exceed 1m, the RFI filter must be
integrated on a backplate connected to the earth.

The specific design of these filters makes it possible
to connect to IT power supplies. The installer should,
however, ensure that insulation supervision systems
dedicated to these installations are suitable for
monitoring electrical equipment that may contain
electronic variable speed drives.
