A.1.3 EMC Guidelines Compliance
Electromagnetic compatibility (EMC) describes the ability of electronic and electrical devices
or systems to work properly in the electromagnetic environment and not to generate

In other words, EMC includes two aspects: The electromagnetic interference generated by
a device or system must be restricted within a certain limit; the device or system must have

interference. Besides the CE compliance described in this chapter, take
measures to avoid the radio interference if required.
The integrator of the system installed with the AC drive is responsible for compliance of the
system with the European EMC directive and standard EN 61800-3: 2004 +A1: 2012 Category
C2, C3 or C4 according to the system application environment.
