Warning
Failure to follow these instructions may result in personal injury or product damage.
Caution
Warning
1. Fail-safe device must be installed when using the unit with machinery that may cause
serious injury or substantial economic loss. (e.g. nuclear power control, medical
equipment, ships, vehicles, railways, aircraft, combustion apparatus, safety equipment,
crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in re, personal injury, or economic loss.
2. Install on a device panel to use.
Failure to follow this instruction may result in re.
3. Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in re.
4. Check 'Connections' before wiring.
Failure to follow this instruction may result in re.
5. Do not disassemble or modify the unit.
Failure to follow this instruction may result in re.

Cautions during Use
1. Follow instructions in 'Cautions during Use'. Otherwise, It may cause unexpected
accidents.
2. 5VDC power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
3. For using the unit with the equipment which generates noise (switching regulator,
inverter, servo motor, etc.), ground the shield wire to the F.G. terminal.
4. When using switching mode power supply, frame ground (F.G.) terminal of power supply
should be grounded.
5. Check the wire type and response frequency when extending wire because of distortion
of waveform or residual voltage increment etc by line resistance or capacity between
lines.
6. This unit may be used in the following environments.
