Specifications
Control Panels with Natural Cooling
• Do not mount the Machine Controller at the top of the control panel, where the hot air that is generated
inside the panel collects.
• Leave sufficient space above and below the Units, and maintain adequate distances from other devices,
cable ducts, and other objects to ensure suitable air circulation.
• Do not mount the Machine Controller in any direction other than the specified direction.
• Do not mount the Machine Controller on top of any device that generates a significant amount of heat.
• Do not subject the Machine Controller to direct sunlight.
Control Panels with Forced-air Cooling
Use one of the following methods to ensure 0.03 m

/min average airflow below the CPU Unit.
• Forced draft method (A fan or a similar device is used to circulate the air in the interior and the exterior
of the panel.)
• Forced circulation method (A fan or a similar device is mounted to the airtight panel to circulate the air
inside.)
Use the following guideline when selecting the fan:
• CPU Unit’s resistance to air flow: 6 × 10
