Precautions for Direct Installation
It is necessary to provide a clearance of 50 mm or more in the horizontal direction and
a clearance of 100 mm or more in the upward direction near the controller.
•
Provide a ventilation space at the side of the controller so that the air vent
holes are not blocked. The space equal to the length of the legs should be
kept below the lower surface.
Failure to do so could cause the cooling performance to drop or to faults.
•
DO NOT stack the controllers.
•
DO NOT place any object on top of the controller.
