When the generic emission standards are used, the drives are required to comply with Table 10.39.
Environment Generic standard Conducted emission requirement
according to EN 55011 limits
First environment
(home and oce)
EN/IEC 61000-6-3 Emission standard for residential, commercial,
and light industrial environments.
Class B
Second environment
(industrial environment)
EN/IEC 61000-6-4 Emission standard for industrial environments. Class A Group 1
Table 10.39 Generic Emission Standard Limits
10.14.3 Immunity Requirements
The immunity requirements for drives depend on the installation environment. The requirements for the industrial
environment are higher than the requirements for the home and oce environment. All Danfoss drives comply with the
requirements for both the industrial and the home/oce environment.
To document immunity against burst transient, the following immunity tests have been performed on a drive (with options
if relevant), a shielded control cable, and a control box with potentiometer, motor cable, and motor. The tests were
performed in accordance with the following basic standards. For more details, see Table 10.40
