Installation method (example of single-phase 200 V class model)
 The mounting method is the same for the three-phase 200 V class model and the three-phase
400 V class model.
＊
1. The ground at both ends of the shielded cable must be connected to ground with a cable clamp.
From the viewpoint of harmonic current, the CE-mark (IEC 61000-3-2 and IEC61000-3-4)
requires an input-side AC reactor (ALI) or facility to suppress harmonic current. The noise terminal
voltage and radiation noise pass even if the input-side AC reactor (ALI) is removed.
The filter is integrated and
mounted between the
inverter and the metal plate.
Remove paint from the
ground terminal, ensure
sufficient contact area, and
ground. ( part in the
