2.8.1 Emission Requirements
According to the EMC product standard for frequency
converters, EN/IEC 61800-3:2004 the EMC requirements
depend on the intended use of the frequency converter.
The EMC product standard defines 4 categories. The 4
categories and the requirements for mains supply voltage
conducted emissions are defined in Table 2.11.
Category Definition
Conducted
emission
requirement
according to
the limits given
in EN 55011
C1 Frequency converters installed in
the first environment (home and
office) with a supply voltage less
than 1000 V.
Class B
C2 Frequency converters installed in
the first environment (home and
office) with a supply voltage less
than 1000 V, which are neither
plug-in nor movable and are
intended to be installed and
commissioned by a professional.
Class A Group 1
C3 Frequency converters installed in
the second environment (industrial)
with a supply voltage lower than
1000 V.
Class A Group 2
C4 Frequency converters installed in
the second environment with a
supply voltage equal to or above
1000 V or rated current equal to or
above 400 A or intended for use in
complex systems.
No limit line.
An EMC plan
should be
made.
