2 HG5G/4G/3G/2G-V
2.7 Installation
Operating Environment
●
For designed performance and safety of the HG5G/4G/3G/2G-V, do not install the HG5G/4G/3G/2G-V in the following
environments:
• Where dust, briny air, or iron powder exist.
• Where oil or chemical splashes for a long time.
• Where space is filled with oil mist.
• Where direct sunlight falls on the main unit.
• Where strong ultraviolet rays fall on the main unit.
• Where corrosive or combustible gasses exist.
• Where shocks or vibrations are transmitted.
• Where condensation occurs due to rapid temperature change.
• Where high-voltage or arc-generating equipment (electromagnetic contactors or circuit protectors) exists in close
proximity.
Ambient Temperature
●
• Allow sufficient space for ventilation, and install the equipment away from heat sources.
• Allow at least 100mm between the HG5G/4G/3G/2G-V and walls or other equipment.
• Do not install the HG5G/4G/3G/2G-V where the ambient temperature exceeds the rated operating ambient
temperature range. When mounting the HG5G/4G/3G/2G-V in such locations, provide a forced air-cooling fan or
air-conditioner to keep the ambient temperature within the rated temperature range.
• The HG5G/4G/3G/2G-V is designed to install on a vertical plane so that natural air-cooling is provided. If you install
it using any other orientation, use forced-air cooling, or lower the ambient operating temperature.
About Derating
●
HG5G/4G/3G/2G-V suppresses the temperature rise inside the product by reducing the backlight brightness when the
ambient operating temperature becomes high.
Relationship between the ambient operating temperature and brightness is as follows.
Brightness
100%
40%
0%
-20°C
