Installation of the heatsink portion
outside the enclosure for use
7.4 Installation of the heatsink portion outside the enclosure
for use
When encasing the inverter in an enclosure, the generated heat amount in an enclosure can be greatly reduced by
installing the heatsink portion of the inverter outside the enclosure. When installing the inverter in a compact
enclosure, etc., this installation method is recommended.
7.4.1
When using a heatsink protrusion attachment (FR-A7CN)
For the FR-A740-00023 to 03610, a heatsink can be protruded outside the enclosure using a heatsink protrusion
attachment (FR-A7CN). (For the FR-A740-04320 or more, 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 attachment (FR-A7CN)
to the inverter, refer to a manual of "heatsink protrusion attachment".
7.4.2
Protrusion of heatsink of the FR-A740-04320 or more
(1) Panel cutting
Cut the panel of the enclosure according to the inverter capacity.
