Installation Of The Heatsink Portion Outside The Enclosure For Use; When Using A Heatsink Protrusion Attachment (Fr-A7Cn); Protrusion Of Heatsink Of The Fr-A740-03250 Or Higher - Mitsubishi Electric FR-A720-00030-NA Instruction Manual

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-A720-00080 to 03460, FR-A740-00015 to 02600, a heatsink can be protruded outside the enclosure
using a heatsink protrusion attachment (FR-A7CN). (For the FR-A740-03250 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 attachment (FR-A7CN)
to the inverter, refer to a manual of "heatsink protrusion attachment".
