Part 1 Installation
3. 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°C.
Install the controller vertically on a wall, as shown below. This controller is cooled by forced ventilation (air blows
out from the top). Accordingly, heed the aforementioned installation direction and provide a minimum clearance
of 100 mm above and 50 mm 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 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 approx. 50 mm between the controller and the closest regenerative resistance box, and a
clearance of approx. 10 mm between regenerative resistance boxes.
