Emission Requirements; Emc Immunity Requirements - Danfoss iC2-Micro Series Design Manual

Design Guide | iC2-Micro Frequency Converters
According to the EMC Directive, a system is defined as a combination of several types of equipment, finished products, and/or
components combined, designed, and/or put together by the same person (system manufacturer) intended to be placed on the
market for distribution as a single functional unit for an end user and intended to be installed and operated together to perform a
specific task.
The EMC directive applies to products/systems and installations, but in case the installation is built up of CE-marked products/
systems, the installation can also be considered compliant with the EMC directive. Installations are not CE-marked.
According to the EMC Directive, Danfoss as a manufacturer of products/systems is responsible for obtaining the essential
requirements of the EMC directive and attaching the CE mark. For systems involving load sharing and other DC terminals, Danfoss
can only ensure compliance with EMC Directive when combinations of Danfoss products are connected as described in the
technical documentation.
If installed in residential environments, and not compliant to class C1, the drive may not provide adequate protection to radio
reception in such locations.
In such cases, supplementary mitigation measures might be required, for example, the use of shielding or increasing the
l
distance between affected products.

Emission Requirements

According to the EMC product standard for AC drives, EN/IEC 61800-3, the EMC requirements depend on the intended use of the drive.
Four categories are defined in the EMC product standard. The definitions of the 4 categories together with the requirements for mains
supply voltage conducted emissions are given in
Table 35: Emission Requirements
Compliance class
C1
C2
C3
C4
The drives are designed to comply to 1 of the following 4 categories, defined in the EMC product standard, EN/IEC 61800-3.
When the drive is connected to the public supply network, without the external reactors installed, the drive may not comply with
harmonic emission requirements of IEC/EN 61000-3-2 and IEC/EN 61000-3-12.

EMC Immunity Requirements

4.6.3
The immunity requirements for drives depend on the environment in which they are installed. The requirements for the industrial
environment are higher than the requirements for the home and office environment. All Danfoss drives comply with the requirements
for the industrial environment. Therefore, they also comply with the lower requirements for home and office environment with a large
safety margin.

Intended use of the drive
Drives installed in the 1st environment (home and office) with a supply voltage less than 1000 V.
Drives installed in the 1st environment (home and office) with a supply voltage less than 1000 V, which are
neither plug-in nor movable and are intended for installation and commissioning by a professional.
Drives installed in the 2nd environment (industrial) with a supply voltage lower than 1000 V.
Drives installed in the 2nd environment (industrial) 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.
