Please read the following safety considerations before use.

Safety Considerations

Please observe all safety considerations for safe and proper product operation to

※

avoid hazards.

※

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 his instruc ion may result in personal injury, economic loss or re.

2. Do not use the unit in the place where ammable/explosive/corrosive gas, high

humidity

Failure to follow his instruc ion may result in explosion or re.

3. Install on a device panel to use.

Failure to follow his instruc ion may result in re.

4. Do not connect, repair

Failure to follow his instruc ion may result in re.

5. Check 'Connections' before wiring.

Failure to follow

6. Do not disassemble or modify the unit.

Failure to follow his instruc ion may result in re.

1. Use the unit within the rated specications.

Failure to follow his instruc ion may result in re or product damage.

2. Do not short the load.

Failure to follow his instruc ion may result in product damage by re.

3. Do not use the unit near the place where there is the equipment which generates
strong magnetic force or high frequency noise and strong alkaline, strong acidic

exists.

Failure to follow his instruc ion may result in product damage.

Cautions during Use

1. Follow instructions in 'Cautions during Use'. Otherwise, It may cause unexpected
accidents.

2. 5VDC, 12-24VDC power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.

3. For using he unit with the equipment which generates noise (switching regulator, inverter,
servo motor, etc.), ground the shield wire to the F.G. terminal.

4. Ground the shield wire to the F.G. terminal.

5. When using switching mode power supply, frame ground (F.G ) terminal of power supply
should be grounded.

6. Wire as short as possible and keep away from high voltage lines or power lines,
to prevent inductive noise.

7. 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.

8. This unit may be used in the following environments.

Indoors (in the environment condi ion rated in 'Specications')
