2.1.2 Installation in control box
When installing the drive unit in a control box, the internal temperature of the control box must not
exceed the permissible value due to drive-unit generated heat and peripheral-generated heat.
Placing a heat sink outside the control box can reduce the heat generated inside the control box
Refer to: Chapter 7, 7.1.3 Option list (External heat sink mounting attachment)

NOTICE
Leave the specified clearances between the drive unit and control box walls or other
equipment. Not doing so can cause a failure. In addition, improper convection of air
in the control box will reduce the heat dissipation effect. Fully consider the
equipment layout in the control box and the use of a cooling fan for ventilation, for
example.
