4.14.3 EMC environments in residential and industrial areas
Description
IEC 61800-3 de󹪝nes EMC requirements for using variable-speed drives in the following 2
environments:
• 1st environment: Residential environment
The residential environment includes residential buildings or locations where the drive is
directly connected to the public low-voltage grid without using an intermediate transformer.
Equipment and systems that are operated on the public low-voltage grid must comply with
de󹪝ned limit values for interference immunity and interference emission. The limit values are
speci󹪝ed in the applicable standards. Especially for interference emissions, increased
requirements apply regarding the 2nd environment.
• 2nd environment: Industrial Environment
An industrial environment includes all other installations that are not directly connected to
the low-voltage supply for residential buildings. The 2nd environment essentially
encompasses industrial areas that are supplied from the medium voltage grid via their own
transformers.
4.14.4 EMC category
Description
Together with the associated motors and encoders, including the connecting cables, the
converter forms a variable-speed drive. Product standard IEC61800‑3 de󹪝nes the EMC
requirements for a variable-speed drive. Product standard IEC61800‑3 calls a variable-speed
drive a "Power Drive System" (PDS).
IEC 61800-3 de󹪝nes the categories for electromagnetic compatibility in the 1st environment
and the 2nd environment.
