An external radio interference suppression filter should be installed in the
immediate proximity of the variable frequency drive. In order to have an IP66
degree of protection, DX-EMC… radio interference suppression filters must
be installed inside an enclosure (IP66). In this case, the connection to the
variable frequency drive will require a screened cable with a screen braid that
is terminated at both ends to the protective earth (PES) across a large area.
