Heat Sink Outside Mounting Attachment (Mr-Jacn) - Mitsubishi Electric MR-J2S-*B Series Instruction Manual

12. OPTIONS AND AUXILIARY EQUIPMENT

12.1.10 Heat sink outside mounting attachment (MR-JACN)

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.
