7.1.5 Classification of EMC performance
General classes of EMC performance are available as detailed below:
Class 1: General Industrial
Compliance with European Standard EN 61800-3 (EMC Product Standard for
Power Drive Systems) for use in Second Environment (Industrial).
Table 7-2 General industrial application
EMC Phenomenon Standard Level
Radiated emissions EN 55011 Level A1 Emissions:
Conducted emissions EN 61800-3 Limits complying with EN 55011,
Class A, Group 2
Electrostatic discharge EN 61000-4-2 8 kV air discharge
Burst interference EN 61000-4-4 2 kV power cables,
1 kV control cables
Immunity:
Radio-frequency
electromagnetic field EN 61000-4-3 26–1000 MHz, 10 V/m
Class 2: Industrial application with filter
This level of EMC performance will allow the manufacturer/installer to certify their
equipment themselves for compliance with the EMC directive for the industrial
environment, as far as the EMC performance characteristics of the power drive
system are concerned. Performance limits are as specified in the Generic Industrial
Emissions and Immunity Standards EN 61000-6-4 und EN 61000-6-2.
