Classification of EMC behavior

EMC environments and EMC categories are defined as follows in the EMC product standard
EN 61800-3:
Environments
First environment (public systems)
An environment that includes domestic premises and establishments that are connected
directly to a public low-voltage line supply without the use of an intermediate transformer.
Examples: houses, apartments, commercial premises or offices in residential buildings.
Second environment (industrial systems)
An environment that includes all other establishments that are not connected directly to a
public low-voltage line supply.
Examples: industrial and technical areas of buildings fed from a dedicated transformer.
Categories
Category C1
Drive systems with a rated voltage < 1000 V, which are intended for use in the first
environment.
Drive systems which correspond to category C1 can be installed in the first environment
without restrictions.
Category C2
Drive systems with a rated voltage < 1000 V, which are neither plug-in devices nor moveable
devices and which, when used in the first environment, are intended only to be installed and
commissioned by an expert.
Drive systems which correspond to category C2 may only be used in the first environment if
they are installed by an expert, with limit values for electromagnetic compatibility observed.
Note
Professional person
An expert is a person or organization with the necessary experience for installing and/or
commissioning drive systems (Power Drive Systems - PDS), including the associated EMC
aspects.
Category C3
Drive systems with a rated voltage < 1000 V, which are intended for use in the second
environment and not for use in the first environment.
Drive systems which correspond to category C3 may only be installed in the second
environment.
