D-1-2 Installation for MX2 series
Model 3-ph. 200 V class and 3-ph. 400 V class are the same concept for the
installation.
*) Both earth portions of the shielded cable must be connected to the earth
point by cable clamps.
Input choke or equipment to reduce harmonic current is necessary for CE
marking (IEC 61000-3-2 and IEC61000-3-4) from the harmonic current point
of view, even conducted emission and radiated emission passed without the
input choke.

Metal plate (earth)
Earth line is connected to the
heatsink of the inverter
(or PE terminal for bigger models)

EMC filter
(Foot-print)
Cable clamp *
The filter is a footprint type, so it is located
between the inverter and the metal plate.
Remove the insulation material coating of the
earth contact portions so to obtain good
grounding condition.
