Control Panel Installation

To ensure system reliability and safety, the system must be designed and configured according to the
installation environment (temperature, humidity, vibration, shock, corrosive gases, overcurrent, noise,
etc.).

Temperature

Panels have been reduced in size due to space-saving and miniaturization in devices and systems, and
the temperature inside the panel may be at least 10 to 15°C higher than outside the panel. Implement
the following measures against overheating at the installation site and in the panel, and allow a suffi-
cient margin for the temperature.
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
devices such as fans or coolers. When using this method, observe the following points.
• Do not install the Controller at the top of the panel, where hot air tends to stagnate.
• To provide ventilation space above and below the Controller, leave sufficient distance from other
devices, wiring ducts, etc.
• Do not mount the Units in the wrong direction (e.g., vertically or upside down). Doing so may
cause abnormal heating in the Controller.
• Do not install the Controller directly above any heat-generating equipment, such as heaters,
transformers, and devices with high resistance.
• Do not install the Controller in a location exposed to direct sunlight.
