3.4 Heat Radiation and Installation
Design the control panel size, controller layout and cooling method in such a way that the temperature
around the controller will not exceed 40C.
Install the controller vertically on a wall, as shown below. Since cooling is provided by way of natural
convection, always observe this installation direction and provide a minimum clearance of 50 mm above
and below the controller to ensure sufficient natural airflows.
When installing multiple controllers side by side, providing a ventilation fan or fans above the controllers
will help maintain a uniform temperature around the controllers.
Keep the front panel of the controller away from the wall (enclosure) by at least 95 mm.
Regardless of whether your system consists of a single controller or multiple controllers, provide sufficient
clearances around each controller so that it can be installed/removed easily.
