3.7 Installation
Operating Environment
●
For designed performance and safety of the HG4G/3G, HG2G-5F, do not install the HG4G/3G, HG2G-5F 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 HG4G/3G, HG2G-5F and walls or other equipment.
• Do not install the HG4G/3G, HG2G-5F where the ambient temperature exceeds the rated operating ambient
temperature range. When mounting the HG4G/3G, HG2G-5F in such locations, provide a forced air-cooling fan or
air-conditioner to keep the ambient temperature within the rated temperature range.
• The HG4G/3G, HG2G-5F 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.
