Chapter 7 EMC

7.1 Definition

Electromagnetic compatibility (EMC) describes the ability of electronic and
electrical devices or systems to work properly in the electromagnetic environment
and not to generate electromagnetic interference that influences other local devices
or systems.

7.2 Introduction to EMC Standard

According to requirements of China National Standard GB/T12668.3(Equates
IEC/EN 61800-3:2004), variable frequency AC drives must meet two aspects of
requirements: one is electromagnetic interference generation level, and the other is
capability of electromagnetic interference resistance.

8000m series VFD satisfies the requirements of standard IEC/EN 61800-3:
2004(Adjustable speed electrical power drive systems part 3: EMC requirements
and specific test methods), which equates China National Standard GB/T12668.3.

7.3 EMC Guideline

7.3.1 Harmonic Influence

Higher harmonics of power input may damage the VFD. Thus, in case of
applications where power quality is rather poor, it is recommended to install an AC
input reactor.

7.3.2 Installation Notices for Electromagnetic Interference

There are two kinds of electromagnetic interference, one is the electromagnetic
noise from environment around which interferes the VFD, and the other is
emission and harmonic generated by the VFD which interferes other devices.
