9 Electro-Magnetic Compatibility (EMC)
9.1.5 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 9-1
EMC Phenomenon
Emissions:
Radiated Emissions
Conducted Emissions
Immunity:
Electrostatic Discharge
Burst Interference
Radio Frequency Electromagnetic Field IEC 1000-4-3
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.
