8. SUPPLEMENTARY INFORMATION
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
EMC Phenomenon
Emissions:
Radiated Emissions
Conducted Emissions
Immunity:
Electrostatic Discharge
Burst Interference
Radio Frequency Electromagnetic Field
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.
