5-25.1 Installation5.1.1 Installation Environment and SpaceAvoid installing the unit in the following locations:• Direct sunlight and ambient temperatures outside the range of 0°C to +55°C.(When installing the unit in a control panel, carefully consider radiation. Also, do not install the unitimmediately above any devices generating heat.)• Ambient humidity outside the range of 30% to 85% RH (at 25°C, non-condensing).• Sudden temperature changes causing condensation.• Inflammable or corrosive gas.• Excessive airborne dust, metal particles or saline matter.• Benzine, paint thinner, alcohol or other organic solvents or strong alkaline solutions such as ammoniaor caustic soda.• Direct vibration, shock or direct drop of water.• Influence from power transmission lines, high voltage equipment, power cables, power equipment,radio transmitters, or any other equipment that would generate high switching surges.Measures regarding noise• Influence from power transmission lines, high voltage equipment, power cables, power equipment,radio transmitters, or any other equipment that would generate high switching surges• If noise occurs in the power supply line even after the above countermeasures are taken, it isrecommended to supply power through an insulation transformer, noise filter, or like.Measures regarding heat discharge• Always install the unit orientated with the tool port facing outward on the bottom in order to prevent thegeneration of heat.• Do not install the FPΣ control unit as shown below.• Do not install the unit above devices which generate heat such heaters, transformers or large scaleresistors.
