 Arrangement of the ventilation fan and inverter
Heat generated in the inverter is blown up from the bottom of the unit as warm air by the cooling fan. When installing a
ventilation fan for that heat, determine the place of ventilation fan installation after fully considering an air flow. (Air passes
through areas of low resistance. Make an airway and airflow plates to expose the inverter to cool air.)
<Good example>
Arrangement of the ventilation fan and inverter
2.3.5
When encasing the inverter to an enclosure, the heat generated in the enclosure can be greatly reduced by protruding the heat
sink of the inverter.
When installing the inverter in a compact enclosure, etc., this installation method is recommended.
 When using the panel through attachment (FR-A8CN)
For the FR-F820-00105(2.2K) to 04750(110K) and the FR-F840-00023(0.75K) to 03610(160K), a heat sink can be protruded
outside the enclosure using a panel through attachment (FR-A8CN). (For the FR-F840-04320(185K) or higher, the attachment
is not necessary when the heat sink is to be protruded.)
For a panel cut dimension drawing and an installation procedure of the panel through attachment (FR-A8CN) to the inverter,
refer to a manual of FR-A8CN.
 Protrusion of heat sink for the FR-F840-04320(185K) or higher
 Panel cutting
Cut the panel of the enclosure according to the inverter capacity.
