Introduction

2.10.2 Emission Requirements

According to the EMC product standard for adjustable speed frequency converters EN/IEC 61800-3:2004, the EMC
requirements depend on the environment in which the frequency converter is installed. These environments along with the
mains voltage supply requirements are defined in Table 2.11.
Category Definition
C1 Frequency converters installed in a home and office environment with a supply
voltage less than 1,000 V.
C2 Frequency converters installed in the home and office environment with a supply
voltage less than 1,000 V. These frequency converters are not plug-in and cannot be
moved and are intended to for professional installation and commissioning.
C3 Frequency converters installed in an industrial environment with a supply voltage
lower than 1,000 V.
C4 Frequency converters installed in an industrial environment with a supply voltage
equal to or above 1,000 V or rated current equal to or above 400 A or intended for
use in complex systems.
Table 2.11 Emission Requirements
When the generic emission standards are used, the frequency converters are required to comply with Table 2.12
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.
