5.9 Electromagnetic compatibility (EMC)
The VARIPACK frequency inverters comply with the
EU EMC directives 2014/30/EU and 2004/108/EC.
The product standard EN61800-3 applies to the inter-
ference immunity of frequency inverters. The frequency
inverters meet the requirements for the first and second
environment.
The interference emission of the frequency inverters is
regulated by the product standard EN 61800-3, which
distinguishes between categories C1 – C4. Compared
with the generic standards, the category C2 according
to EN61800-3:2004 corresponds to
EN61000-6-4-2007+A1: 2011. The category C3 is not
transferable. The text below only refers to C categories.
General EMC requirements:
• Use of a shielded cable between FI and motor (mo-
tor cable).
– Connect shield on both sides.
– Route the shielded cable up to the VARIPACK in
the switch cabinet and lay it properly through an
EMC screwed cable gland (IP55/66), resp. con-
nect it with low impedance to the back panel/PE
rail (IP20).
• The motor cable
– should not cross other cables. If it does, crossov-
ers must be made at a 90° angle!
– should be installed separately from the feed line
and the control lines, if possible. If a parallel in-
stallation is unavoidable, maintain a clearance of
at least 0.25m.
• Control Cable
All analog signal cables should be suitably shielded.
Twisted pair cables are recommended.
Information
FM.+6-4 .. FM.+14-4 are classified as profes-
sionally used device according to
EN61000-3-2:2014. Before connecting them to
the public low-voltage supply network, approval
from the energy supply company must be ob-
tained.
Information
FM.+18-4 .. FP.+72-4 meet all requirements of
the standard EN61000-3-12:2011 (see chapter
Analysis of harmonics, page 22).
FMY+6-4 .. FPW+90-4, FSW+370-4, FSW+480-4 and
FMU+6-4 .. FSU+480-4:
• are equipped as standard with an integrated EMC fil-
ter for category C2 (motor cable length max. 5 m) .
• If the EMC requirements of category C3 are suffi-
cient, the line length between FI and motor may be
up to 25m.
WARNING
Without the use of an external EMC filter, high-
frequency interferences may occur in the
voltage supply system!
In a residential environment, this drive constella-
tion may cause high-frequency interferences
which may require mitigation measures.
