Heatsink Protrusion Attachment (Fr-A7Cn) - Mitsubishi Electric FR-A700 Instruction Manual

Heatsink protrusion attachment (FR-A7CN)

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 in-
stalling the inverter in a compact enclosure, etc., this installation method is recommended.
For the FR-A740-00023 to 03610, a heatsink can be protruded outside the enclosure using a
heatsink protrusion attachment (FR-A7CN). For a panel cut dimension drawing and an instal-
lation procedure of the heatsink protrusion attachment (FR-A7CN) to the inverter, refer to a
manual of "heatsink protrusion attachment".
For the panel cut dimensions of the inverters FR-A740-04320 or more refer to Fig. A-17 in the
appendix.
