Heatsink protrusion attachment procedure

SPECIFICATIONS

7.4 Heatsink protrusion attachment procedure

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-F720-2.2K to 110K, FR-F740-0.75K to 160K, a heatsink can be protruded outside the enclosure using a

heatsink protrusion attachment (FR-A7CN). 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 (FR-

A7CN01 to 10)".

7.4.2 Protrusion of heatsink of the FR-F740-185K or more

(1) Panel cutting

Cut the panel of the enclosure according to the inverter capacity.

• FR-F740-185K, 220K • FR-F740-250K, 280K, 315K
