International English
Class 3: Filtered - for residential, commercial and light industry
This level of performance will allow the manufacturer / assembler to self-certify
compliance of their apparatus with the EMC directive for the residential,
commercial and light industrial environment as regards the EMC performance
characteristics of the power drive system. Performance limits are as specified in
the generic emission and immunity standards EN 50081-1 and EN 50082-1.

EMC Phenomenon
Emissions:
Radiated Emissions*
Conducted Emissions
Immunity:
Supply Voltage Distortion
Voltage Fluctuations, Dips, Unbalance,
Frequency Variations
Magnetic Fields
Electrostatic Discharge
Burst Interference
Radio Frequency Electromagnetic
Field, amplitude modulated
Radio-frequency Electromagnetic Field,
pulse modulated
* These limits are dependent on the inverter being correctly installed inside a
metallic switchgear enclosure. The limits will not be met if the inverter is not
enclosed.
Notes
To achieve these performance levels, you must not exceed the default Pulse
frequency nor use cables longer than 25 m.
The MICROMASTER inverters are intended exclusively for professional
applications. Therefore, they do not fall within the scope of the harmonics
emissions specification EN 61000-3-2.
Maximum mains supply voltage when filters are fitted is 460 V.
