External EMC Filter for Models with Feature E
An external EMC filter can be connected to the inputs lines of
the converter. However, a small choke has to be included in the
phase line to avoid interferences between the internal and
external filter, which would cause dramatically increased low
harmonics.

Fig. 14a and 14b show the conducted emissions smoothed by
an external filter. The standards EN 55011 and 55022 define
limits for conducted (quasi)peak and conducted average
emissions. In general the limits for average emissions are
more difficult to meet.

Note: This filter allows for connection of an IEC inlet and is
available with 1 or 2 incorporated fuses.
A similar filter with AMP terminals (6.3 20 mm) is also available
(Schurter FMLB 5500.2028).
