Part 1 Installation
2. Heat Radiation and Installation
Design the control panel size, controller layout and cooling method so that the surrounding air temperature
around the controller will be kept at or below 40
qC.
Install the controller vertically on a wall, as illustrated below. The controller will be cooled by forced
ventilation (exhaust air will be discharged from the top). Be sure to install the controller in the
aforementioned direction and provide a minimum clearance of 150 mm above and 150 mm below the
controller.
If multiple controllers are to be installed side by side, providing additional fans on top of the controllers will
help maintain a uniform surrounding air temperature.
Provide a minimum clearance of 150 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.
Provide a clearance of approximately 50 mm between the regenerative resistor and the controller, and a
clearance of approximately 10 mm between the regenerative resistors.
