5.5 Electromagnetic compatibility (EMC)
For an overview, see figure 15, page 59.
The VARIPACK frequency inverters comply with the
EU EMC directives 2014/30/EU and 2004/108/EC.
Interference immunity:
• EN 61000-6-1:2007, immunity for residential, com-
mercial and light industrial environments.
• EN 61000-6-2:2005, immunity standard for industrial
environments.
The emission of the frequency inverters is regulated by
the product standard EN 61800-3, which distinguishes
between categories C1 - C4. Compared with the gen-
eric standards, the category C2 according to EN
61800-3:2004 corresponds to EN 61000-6-4-2011. The
category C3 is not transferable. The text below only
refers to C categories.
General EMC requirements for meeting category C2:
• Use of a shielded cable between FI and motor (mo-
tor cable), see figure 10, page 51.
– Connect shield on both sides.
– Use a compressor terminal box made of metal
and a screwed EMC cable gland.
– Guide the shield in the switch cabinet to the
VARIPACK and connect it on the cable fixture of
the VARIPACK .
• The motor cable
– should not cross other cables. If they do, crossov-
ers must be made at a triangle!
– should be installed separately from the supply line
and the control lines, if possible. If a parallel in-
stallation is unavoidable, maintain a clearance of
at least 0.25 m.
FDU+6 .. FJU+145:
• are equipped as standard with an integrated EMC fil-
ter for category C2.
• meet the above-mentioned generally applicable
EMC requirements and the requirements of category
C2.
– However, for some types, a metal switch cabinet
with attenuation must be used, to ensure that the
limit values of the radiated interferences are not
exceeded (see figure 15, page 59).
If the EMC requirements of category C3 are sufficient,
the line length between FI and motor may be up to
50 m. In this case, it will not be necessary to use a spe-
cial switch cabinet either.
FKU+180 .. FKU+260:
• are equipped with an integrated EMC filter for cat-
egory C3. To meet category C2, external EMC filters
are available on request.
Information
The VARIPACK frequency inverters can still
generate interferences in residential areas. In
this case, additional protective measures must
be taken!
