6SE6400-5AA00-0BP0
Three General classes of EMC performance are available as detailed below
Class 1: General Industrial
Compliance with the EMC Product Standard for Power Drive Systems EN 68100-3 for
use in Second Environment (Industrial) and Restricted Distribution.
Table 8-1 Class 1 - General Industrial
EMC Phenomenon Standard Level
Emissions:
Radiated Emissions EN 55011 Level A1
Conducted Emissions EN 68100-3 Limits under consideration
Immunity:
Electrostatic Discharge EN 61000-4-2 8 kV air discharge
Burst Interference EN 61000-4-4 2 kV power cables, 1 kV control
Radio Frequency Electromagnetic Field IEC 1000-4-3 26-1000 MHz, 10 V/m
Class 2: Filtered Industrial
This level of performance will allow the manufacturer/assembler to self-certify their
apparatus for compliance with the EMC directive for the industrial environment as regards
the EMC performance characteristics of the power drive system. Performance limits are
as specified in the Generic Industrial Emissions and Immunity standards EN 50081-2 and
EN 50082-2.
