3. 2 Precaution for inverter mounting to the enclosure
Enclosure design and layout are important points for controlling EMC. Perform
installation by considering the following points.
(1) Use a metal enclosure.
(2) Use EMI gasket or other conductive packing to where the enclosure door touches
the enclosure body.

(3) It is recommended to
or available as an option. When using an option EMC filter, mask the painting or
plate the area of the enclosure where the EMC filter is mounted so that the electrical
connection can be established between the EMC filter and the ground (earth) of the
enclosure. Confirm that the EMC filter is securely fitted to the enclosure surface.
Confirm that the equipment mounting board inside the enclosure is also connected
to the ground (earth).
