Only Frame Sizes A to F
Class 3: With filter, for residential, commercial and trade applications
This level of EMC performance will allow the manufacturer/installer to certify
compliance of their equipment themselves with the EMC directive for the
residential, commercial and light industrial environment, as far as the EMC
performance characteristics of the power drive system are concerned.
Performance limits are as specified in the Generic Emission and Immunity
Standards EN 61000-6-3 and EN 61000-6-1 in residential applications.

* 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
¾ To achieve these performance levels. you must not exceed the default Pulse
frequency nor use cables longer than 25 m.
¾ 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.
¾ Maximum mains supply voltage when filters are fitted is 460 V.
