Safety Considerations
• Observe all 'Safety Considerations' for safe and proper operation to avoid hazards.
• ᜸ symbol indicates caution due to special circumstances in which hazards may occur.
᜸ Warning
Failure to follow instructions may result in serious injury or death.
01. 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 personal injury, economic loss or fire.
02. Do not use the unit in the place where flammable / explosive / corrosive gas,
high humidity, direct sunlight, radiant heat, vibration, impact or salinity
may be present.
Failure to follow this instruction may result in explosion or fire.
03. Install on a device panel to use.
Failure to follow this instruction may result in fire.
04. Do not connect, repair, or inspect the unit while connected to a power
source.
Failure to follow this instruction may result in fire.
05. Check 'Connections' before wiring.
Failure to follow this instruction may result in fire.
06. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire.
᜸ Caution
Failure to follow instructions may result in injury or product damage.
01. Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
02. Do not short the load.
Failure to follow this instruction may result in fire.
03. 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 this instruction may result in product damage.
Cautions during Use
• Follow instructions in 'Cautions during Use' .
Otherwise, It may cause unexpected accidents.
• 12 - 24 VDCᜡ power supply should be insulated and limited voltage / current or Class 2,
SELV power supply device.
• 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.
• Ground the shield wire to the F.G. terminal.
• When supplying power with SMPS, ground the F.G. terminal and connect the noise
canceling capacitor between the 0 V and F.G. terminals.
• Wire as short as possible and keep away from high voltage lines or power lines, to
prevent inductive noise.
• 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.
• This unit may be used in the following environments.
- Indoors (in the environment condition rated in 'Specifications')
- Altitude max. 2,000 m
- Pollution degree 2
- Installation category II
