5 Installation
High Temperatures
Use the following cooling methods as required, taking into account the ambient temperature and the
amount of heating inside the panel.
 Natural Cooling
Natural cooling relies on natural ventilation through slits in the panel, rather than using cooling devi-
ces such as fans or coolers. When using this method, observe the following points.
• Do not install the Box PC at the top of the panel, where hot air tends to stagnate.
• To provide ventilation space above and below the Box PC, leave sufficient distance from other
devices, wiring ducts, etc.
• Do not mount the Box PC in the wrong direction (e.g., vertically or upside down). Doing so may
cause abnormal heating in the Box PC.
• Do not install the Box PC directly above any heat-generating equipment, such as heaters or
transformers.
• Do not install the Box PC in a location exposed to direct sunlight.
