Instruction Manual

7.1 Operating Environment

For designed performance and safety of the Touch, do not install the Touch in the following

environments:

• Where dust, briny air, or iron particles exist.

• Where oil or chemical splashes for a long time.

• Where oil mist is filled.

• In direct sunlight.

• Where strong ultraviolet rays exist.

• Where corrosive or combustible gasses exist.

• Where the Touch is subjected to shocks or vibrations.

• Where condensation occurs due to rapid temperature change.

• Where high-voltage or arc-generating equipment (electromagnetic contactors or circuit

protectors) exists in the vicinity.

7.2 Ambient Temperature

• Allow sufficient space for ventilation, and install the equipment away from heat sources.

• Allow at least 100mm between the Touch and walls or other equipment.

• Do not install the Touch where the ambient temperature exceeds the rated operating

ambient temperature range. When mounting the Touch in such locations, provide a

forced air-cooling fan or air-conditioner to keep the ambient temperature within the rated

temperature range.

• The Touch 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.

When using the Touch at an ambient temperature of 45°C or higher, reduce the output

current of each output terminal as shown in the figure below.
