11.18 Heat sink outside mounting attachment (MR-J4ACN15K/MR-J3ACN)
Use the heat sink outside mounting attachment to mount the heat generation area of the servo amplifier in
the outside of the cabinet to dissipate servo amplifier-generated heat to the outside of the cabinet and
reduce the amount of heat generated in the cabinet. In addition, designing a compact cabinet is allowed.
In the cabinet, machine a hole having the panel cut dimensions, fit the heat sink outside mounting
attachment to the servo amplifier with the fitting screws (4 screws supplied), and install the servo amplifier to
the cabinet.
Please prepare screws for mounting. They do not come with.
The environment outside the cabinet when using the heat sink outside mounting attachment should be within
the range of the servo amplifier operating environment.
The heat sink outside mounting attachments are used for MR-J4-11KB(-RJ) to MR-J4-22KB(-RJ) and MR-
J4-11KB4(-RJ) to MR-J4-22KB4(-RJ).
