6.5 External EMC filter
In order to provide our customers with a degree of flexibility, external
EMC filters have been sourced from two manufacturers: Schaffner and
Epcos. The external EMC Filter ratings and dimensions information are
available in the Unidrive SP User Guide.
For currents exceeding 300A up to 2500A, suitable filters are also
available from both Epcos and Schaffner as detailed.
• Epcos B84143-B250-5xx (range up to 2500A)
• Schaffner FN3359-300-99 (range up to 2400A)
These filters may not give strict conformity with EN6000-6-4 but in
conjunction with EMC installation guidelines they will reduce emissions
to sufficiently low levels to minimise the risk of disturbance.
6.5.1 Removal of internal EMC filter

When a EMC filter is used, the switching frequency filter
detailed must also be used. Failure to observe this may result
in the EMC filter becoming ineffective and being damaged.
Refer to section 6.4 EMC (Electromagnetic compatibility) on
page 77.
When an EMC filter is used, a permanent fixed ground
connection must be provided which does not pass through a
connector or flexible power cord. This includes the internal
EMC filter.
The installer of the drive is responsible for ensuring
compliance with the EMC regulations that apply where the
drive is to be used.
CAUTION
WARNING
CAUTION
The internal EMC filter must be removed from the drive.
