Emission
The drive contains an in-built filter for basic emission control. An
additional optional external filter provides further reduction of emission.
The requirements of the following standards are met, depending on the
motor cable length and switching frequency.

E2R EN 61800-3:2004 second environment, restricted distribution
(Additional measures may be required to prevent interference)
E2U EN 61800-3:2004 second environment, unrestricted distribution
I Industrial generic standard EN 61000-6-4:2007
EN 61800-3:2004 first environment restricted distribution (The
following caution is required by EN 61800-3:2004)
This is a product of the restricted distribution class according
to IEC 61800-3. In a residential environment this product may
cause radio interference in which case the user may be
required to take adequate measures.
CAUTION
R Residential generic standard EN 61000-6-3:2007
EN 61800-3:2004 first environment unrestricted distribution
EN 61800-3:2004 defines the following:
• The first environment is one that includes residential premises. It
also includes establishments directly connected without intermediate
transformers to a low-voltage power supply network which supplies
buildings used for residential purposes.
• The second environment is one that includes all establishments
other than those directly connected to a low-voltage power supply
network which supplies buildings used for residential purposes.
• Restricted distribution is defined as a mode of sales distribution in
which the manufacturer restricts the supply of equipment to
suppliers, customers or users who separately or jointly have
technical competence in the EMC requirements of the application of
drives.
IEC 61800-3:2004 and EN 61800-3:2004
The 2004 revision of the standard uses different terminology to align the
requirements of the standard better with the EC EMC Directive.
Power drive systems are categorized C1 to C4:
Category
Intended for use in the first or second
C1
environments
Not a plug-in or movable device, and
intended for use in the first environment
C2
only when installed by a professional, or
in the second environment
Intended for use in the second
C3
16
environment, not the first environment
Rated at over 1000 V or over 400 A,
C4 intended for use in complex systems in
the second environment
Note that category 4 is more restrictive than E2R, since the rated current
of the PDS must exceed 400 A or the supply voltage exceed 1000 V, for
the complete PDS.
