14.8 Heat sink outside mounting attachment (MR-J3ACN)
Use the heat sink outside mounting attachment to mount the heat generation area of the servo amplifier in the
outside of the control box to dissipate servo amplifier-generated heat to the outside of the box and reduce the
amount of heat generated in the box, thereby allowing a compact control box to be designed.
In the control box, 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 control box.
The environment outside the control box when using the heat sink outside mounting attachment should be
within the range of the servo amplifier operating environment conditions.
The heat sink outside mounting attachment of MR-J3ACN can be used for MR-J3-11KT(4) to MR-J3-22KT(4).
