Mitsubishi Electronics FR-HC2 ユーザーズマニュアル

When installing a converter inside an enclosure, the heat generated in the enclosure can be greatly reduced by protruding the
heatsink of the converter.
This installation method is recommended when downsizing the enclosure and such. 

For the FR-HC2-7.5K to 75K and FR-HC2-H7.5K to H110K, a heatsink can be protruded outside the enclosure using a
heatsink protrusion attachment (FR-A7CN). (For the 160K or higher, the attachment is not necessary when the heatsink is to
be protruded.)
Refer to the table below for the applicable heatsink protrusion attachments. 
For a panel cut dimension drawing and an installation procedure of the heatsink protrusion attachment (FR-A7CN) to the
converter, refer to a manual of "heatsink protrusion attachment".
