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 shall not be CE marked.
According to the EMC Directive, Danfoss Drives as a manufacturer of product/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, Dan-
foss Drives can only ensure compliance to the EMC Directive when end users connect combinations of Danfoss Drives products
as described in our technical documentation.
rd
If any 3 -party products are connected to the load share or other DC terminals on the AC drives, Danfoss Drives cannot guaran-
tee that the EMC requirements are fulfilled.

6.5.3 Immunity Requirements

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 VLT® drives comply with the re-
quirements for the industrial environment and therefore also comply with the lower requirements for home and office environment
with a large safety margin.
To document immunity against burst transient from electrical phenomena, the following immunity tests have been carried out on a
system consisting of:
• A drive (with options if relevant).
• A shielded control cable.
• A control box with potentiometer, motor cable, and motor.
