anel through attachment (MR-J4ACN15K/MR-J3ACN)
Use the panel through 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 panel through 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 panel through attachment should be within the range of
the servo amplifier operating environment.
The panel through attachments are used for MR-J4-11KB(-RJ) to MR-J4-22KB(-RJ) and MR-J4-11KB4(-RJ)
to MR-J4-22KB4(-RJ).
