Heatsink protrusion attachment procedure
When encasing the inverter to an enclosure, the heat generated in the enclosure can be greatly re-
duced by protruding the heatsink of the inverter.
When installing the inverter in a compact enclosure, etc., this installation method is recommended.
When using a heatsink protrusion attachment (FR-A8CN)
For the FR-A820-00105(1.5K) to 04750(90K) and the FR-A840-00023(0.4K) to 03610(132K), a heatsink
can be protruded outside the enclosure using a heatsink protrusion attachment (FR-A8CN). (For the
FR-A840-04320(160K) or higher, attachment is not necessary when the heatsink is to be protruded.)
For a panel cut dimension drawing and an installation procedure of the heatsink protrusion attach-
ment (FR-A8CN) to the inverter, refer to a manual of FR-A8CN.

● Panel cutting
Cut the panel of the enclosure according to the inverter capacity.
