1.1 Safety Measures
Operating environment
After installing the unit, make sure to use it within the range of the general specifications:
•
Ambient temperature: 0°C–+55°C
•
Ambient humidity: 30%–85% RH (at 25°C non-condensing)
• Maximum altitude: 2000m
• Pollution level: 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
-
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. Maintain at least 100mm of space between these devices
and the unit.
Static electricity
•
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.
Protection of power supply
•
Use a twisted power supply wire.
• Isolate the wiring systems to the CPU, input/output devices, and mechanical power
apparatus.
•
An insulated power supply with an internal protective circuit should be used (FP0-
PSA2 or FP-PS24-050). 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.
•
If using a power supply device without an internal protective circuit, always make sure
power is supplied to the unit through a protective element such as a fuse.
• Be sure to supply power to a CPU and an expansion unit from the same power supply,
and turn the power on and off simultaneously for both.
