page 1-12.
1.7 Installation
●Operating Environment
For designed performance and safety of the HG2J-7U, do not install the HG2J-7U 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 HG2J-7U and walls or other equipment.
• Do not install the HG2J-7U where the ambient temperature exceeds the rated operating ambient temperature
range. When mounting the HG2J-7U in such locations, provide a forced air-cooling fan or air-conditioner to keep
the ambient temperature within the rated temperature range.
• The HG2J-7U 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
HG2J-7U suppresses the temperature rise inside the product by reducing the backlight brightness when the ambient
operating temperature becomes high.
The relationship between ambient operating temperature and brightness when the USB interfaces (USB1 and USB2)
are not used is as follows.
Brightness reduction occurs depending on the output current value of the USB interface.
Depending on each product the values shown above will change. The values given here are representative values are
intended for reference only.

●Installation
• Make a panel cut-out on the panel with the dimensions shown below.
• Use the attached mounting clips to tighten the screws evenly to mount panel: screws must be applied on total of
four places with the specified torque 0.5 to 0.6N∙m.
• Mount the main unit on a rigid panel.
• Do not tighten with excessive force, otherwise the main unit may warp the display, or impair the waterproof
characteristics.
• If the mounting clips are tightened obliquely to the panel, the main unit may fall off the panel.
• When installing the main unit into a panel cut-out, make sure that the gasket is not twisted. Especially when re-
installing, take special care because any twists in the gasket will impair the waterproof characteristics. Also, if
the gasket comes off the main unit, align the convex part of the gasket with the concave part of the front case,
and then insert the gasket fully into the gasket mounting groove without twisting it.
