￫
DC1-1D variable frequency drives do not have an internal radio
interference suppression filter.
An external radio interference suppression filter is required for
operation as per EN 61800-3, ￫ Section 6.8, "Radio
interference suppression filter", page 169.
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.
