3.4 Heat Radiation and Installation
Design the control panel size, controller layout and cooling method so that the temperatures around the controller will
always be kept to 40
°C or below.
Mount the controller vertically on the wall, as shown below. Since cooling is provided by means of natural convection, follow
this orientation and provide a minimum clearance of 50 mm above and below the controller to allow sufficient airflows to
circulate.
If you are installing multiple controllers side by side, provide a fan on top of the controllers to agitate the airflows as an
effective way to keep the surrounding air temperatures constant.
Provide a minimum clearance of 80 mm between the front face of the controller and the wall (cover).
Regardless of whether you are installing one or more controllers, provide sufficient clearances around each controller to
permit easy access for installation and removal of the controller.
