FP7 Analog Output Unit User's Manual
After installing the unit, make sure to use it within the range of the general
specifications:
Ambient temperature: 0°C to +55°C
Ambient humidity: 10%–95% 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
Inflammable 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
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.
Before touching the unit or equipment, always touch some grounded metal
to discharge any static electricity you may have generated (especially in
dry locations). The discharge of static electricity can damage parts and
equipment.
Use a twisted power supply wire.
Insulate the wiring systems to the CPU, input/output devices, and me-
chanical power apparatus.
An insulated power supply with an internal protective circuit should be
used (FP power supply). The power supply for the CPU is a
non-insulated circuit, so if an incorrect voltage is directly applied, the
internal circuit may be damaged or destroyed.
