11.8 Electromagnetic compatibility of the converter
EMC (electromagnetic compatibility) means that the devices function satisfactorily without
interfering with other devices and without being disrupted by other devices. EMC applies when
the emitted interference (emission level) and the interference immunity are matched with each
other.
The product standard IEC/EN 61800-3 describes the EMC requirements placed on "Variable-
speed drive systems".
A variable-speed drive system (or Power Drive System PDS) consists of the converter as well
as the associated electric motors and encoders including the connecting cables.
The driven machine is not part of the drive system.
Note
PDS as component of machines or systems
When you install PDS into machines or systems, additional measures may be required so that
the product standards of these machines or systems is complied with. The machine or system
builder is responsible for taking these measures.
Overview of environments and categories
Environments
IEC/EN 61800-3 makes a distinction between the "first environment" and "second
environment" - and defines different requirements for these environments.
● First environment
Residential buildings or locations at which the PDS is directly connected to a public low-
voltage supply without intermediate transformer.
● Second environment
An environment that includes all other establishments which are not connected directly to a
public low-voltage line supply.
Categories
● Category C1
Power Drive System (PDS) of rated voltage less than 1000 V intended for use in the first
(residential) environment.
● Category C2
Power Drive System (PDS) of rated voltage less than 1000 V, which is neither a plug-in
device nor a movable device, and when used in the first environment, is only intended to be
installed and commissioned by a professional.
● Category C3
Power Drive System (PDS) of rated voltage less than 1000 V intended for use in the second
(industrial) environment and not intended for use within the first (residential) environment.
