Class 3: Filtered - for residential, commercial and trade applications
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 trade applications 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 61000-6-3 and EN 61000-6-1 in
residential.

* 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.
NOTICE
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.
