3.5 Installing the speed controller
The speed controller is designed so that heat is dissipated via air convection.
There must be a clearance of at least 25 mm (0.98 in.) and 50 mm (1.97 in.) clearances in the horizontal and vertical directions,
respectively, between the speed controller and enclosure or other equipment within the enclosure.
Installation direction
Install the speed controller so that the
front panel side is turned in the front
direction or upward.

Note
•
Do not install any equipment that generates a large amount of heat or noise near the speed controller.
•
If the ambient temperature of the speed controller exceeds the upper limit of the operating ambient
temperature, revise the ventilation condition or forcibly cool the area around the speed controller using
a fan in order to keep within the operating ambient temperature.
Installation method
Install the speed controller to a flat metal plate offering excellent vibration resistance.
Remove the front panel of the speed controller and secure the two mounting holes using screws, washers, and nuts
(M4: not supplied). Tighten the screws until no gaps remain between the speed controller and mounting plate.
