Classification of EMC behavior
The EMC environment and the EMC classes are defined in the EMC product standard
EN 61800-3 as follows:
Environment 1
An environment in which there are residential estates and facilities which are connected
directly to a public low-voltage supply network without the use of an intermediate
transformer.
Note
Example: Houses, apartments, commercial units or office roo
ms within a residential building.
Environment 2
An environment in which there are commercial estates and facilities which are not connected
directly to a public low-voltage supply network.
Note
Example: De
veloped commercial sites and other sites which are supplied by a transformer
provided specially for the purpose.
Class C1
Power drive system (PDS) with a rated voltage of less than 1000 V for use in residential
buildings.
