2.4 Line filter
An additional external line filter can be installed into the line supply of the frequency inverter to
maintain the increased noise suppression level (class B as per EN 55011).
2.4.1 Mains filter SK HLD
With a chassis-mounted mains filter, radio interference class B (Class C1)
can be achieved up to a maximum motor cable length of 25 m.
When connecting the mains filter, the "Wiring guidelines" ( Section 2.5.2
and "EMC" ( Section 8.3) must be complied with. In particular, care must
be taken that the pulse frequency is set to the default value (P504). The
mains filter should be placed as close to the side of the frequency inverter as
possible.
The connection is by means of screw connections on the upper (mains) and
lower (inverter) ends of the filter
