3. Heat Radiation and Installation
Design the control panel size, controller layout and cooling method so that the ambient temperature
around the controller will be kept at or below 40°C.
Install the controller vertically on a wall, as illustrated below. The controller will be cooled by natural
convection. Be sure to install the controller in the aforementioned direction and provide a minimum
clearance of 50 mm above and below the controller.
If multiple controllers are to be installed side by side, providing additional suction fans on top of the
controllers will help maintain a uniform ambient temperature.
Provide a minimum clearance of 95 mm between the front side of the controller and a wall (enclosure).
If multiple controllers are to be connected on top of one another, prevent the controller above from
taking in the exhaust air from the controller below.
