Overview
Definition of terms
EMC stands for electromagnetic compatibility.
EMC means that the devices function satisfactorily without interfering with or being disrupted
by other devices. EMC applies when both 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 drives.
A variable-speed drive (referred to as "Power Drive System", or PDS, in IEC/EN 61800-3)
consists of the converter as well as the associated motors and encoders including the
connecting cables.
The driven machine is not part of the drive.
General information
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 drive is directly connected to the public low-
voltage system without an intermediate transformer.
● Second environment
An environment that includes all other equipment which is not connected directly to a public
low-voltage line supply for residential buildings. These are basically industrial areas that
have their own medium-voltage supply via their own transformers.
Note
The drive is intended for commercial or industrial use in stationary machines and systems.
Note
The drive is intended to be installed and put into operation by specially trained personnel, in
observance of EMC conditions and the installation information in the operating instructions and
"EMC layout guidelines" configuration manual.
