3.4.2. EMC test results

The following test results have been obtained using a system with a frequency converter (with options if relevant),
a screened control cable, a control box with potentiometer, as well as a motor and motor screened cable.

Table 3.1: EMC Test Results (Emission, Immunity)
HX, H1, H2 or H3 is defined in the type code pos. 16 - 17 for EMC filters
HX - No EMC filters build in the frequency converter (600 V units only)
H1 - Integrated EMC filter. Fulfil Class A1/B
H2 - No additional EMC filter. Fulfil Class A2
H3 - Integrated EMC filter. Fulfil class A1/B (Enclosure type A1 only)
H4 - Integrated EMC filter. Fulfil class A1
3.4.3. Emission Requirements
According to the EMC product standard for adjustable speed frequency converters EN/IEC61800-3:2004 the EMC requirements depend on the intended
use of the frequency converter. Four categories are defined in the EMC product standard. The definitions of the four categories together with the
requirements for mains line conducted emissions are given in the table below:
Category Definition
C1 frequency converters installed in the first environment (home and office) with a supply
voltage less than 1000 V.
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.
C3 frequency converters installed in the second environment (industrial) with a supply
voltage lower than 1000 V.
C4 frequency converters installed in the second environment with a supply voltage above
1000 V and rated current above 400 A or intended for use in complex systems.
