2.2.3 Emission Requirements

According to the EMC product standard for adjustable
speed frequency converters EN/IEC 61800-3:2004 the EMC
requirements depend on the intended use of the
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
equal to or above 1000 V or rated current equal to or above 400 A or intended for
use in complex systems.
Table 2.3 Emission Requirements
When the generic emission standards are used the
frequency converters are required to comply with the
limits in Table 2.4
Environment Generic standard
First environment EN/IEC 61000-6-3 Emission standard for residential, commercial
(home and office) and light industrial environments.
Second environment EN/IEC 61000-6-4 Emission standard for industrial environments.

2.2.4 Immunity Requirements

The immunity requirements for frequency converters
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and office
