Before You Start

Installation environment
Do not use the FPΣ unit where it will be exposed to the following:
• 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 unit
immediately 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 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.
Static electricity
• Before touching the unit, always touch a grounded piece of metal in order to discharge static electricity.
• In dry locations, excessive static electricity can cause problems.
Cleaning
• Do not use thinner based cleaners because they deform the unit case and fade colors.
Power supplies
• An insulated power supply with an internal protective circuit should be used. The power suppy for the
control unit operation 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 without a protective circuit, power should be supplied through a protective
element such as a fuse.
Power supply sequence
• Have the power supply sequence such that the power supply of the control unit turns off before the
power supply for input and output.
• If the power supply for input and output is turned off before the power supply of the control unit, the
control unit will detect the input fluctuations and may begin an unscheduled operation.
Before turning on the power
When turning on the power for the first time, be sure to take the precautions given below.
• When performing installation, check to make sure that there are no scraps of wiring, particularly
conductive fragments, adhering to the unit.
• Verify that the power supply wiring, I/O wiring, and power supply voltage are all correct.
• Sufficiently tighten the installation screws and terminal screws.
• Set the mode selector to PROG. Mode.
