2 Installation
2.2 Installation environment
To prevent failure or malfunctions, the installation environment must comply with the
specifications of the FP-I4C unit.
After installing the unit, make sure to use it within the range of the general specifications:
• Operating temperature: 0°C to +55°C
• Operating humidity: 30%–85% RH (at 25°C, non-condensing)
• Pollution degree: 2
• Do not use the unit in the following environments:
‒ Direct sunlight
‒ Sudden temperature changes causing condensation
‒ Flammable or corrosive gases
‒ Excessive airborne dust, metal particles or salts
‒ Benzine, paint thinner, alcohol or other organic solvents, or strong alkaline solutions
such as ammonia or caustic soda
‒ Vibration, shock, or direct drop of water
• Avoid noise interference from the following items:
‒ Influence from power transmission lines, high voltage equipment, power cables,
power equipment, radio transmitters, or any other equipment that would generate
high switching surges. Maintain at least 100mm of space between these devices and
the unit.
‒ If noise occurs in the power supply line even after the above countermeasures are
taken, it is recommended to supply power through an isolated transformer, noise
filter, or the like.
• Take measures regarding heat discharge:
‒ Always install the unit orientated with the Ethernet port facing outward on the top in
order to prevent the generation of heat.
‒ Do not install the unit above devices which generate heat, such as heaters,
transformers or large scale resistors.
