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. Do not disassemble or modify the unit.

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.

᜸ 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. Use a dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in fire.

Cautions during Use

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

accidents.

• When connecting an inductive load such as DC relay or solenoid valve to the output,

remove surge by using diodes or varistors.

• Use the product after 0.5 sec of the power input.

When using a separate power supply for the sensor and load, supply power to the

sensor first.

• The power supply should be insulated and limited voltage/current or Class 2, SELV

power supply device.

• Wire as short as possible and keep it away from high voltage lines or power lines to

prevent surge and inductive noise.

• When using switching mode power supply (SMPS), ground F.G. terminal and connect

a condenser between 0V and F.G. terminal to remove noise.

• When using a sensor with a noise-generating equipment (e.g., switching regulator,

inverter, and servo motor), ground F.G. terminal of the equipment.

• This unit may be used in the following environments.

- Indoors (in the environment condition rated in 'Specifications')

- Altitude max. 2,000 m

- Pollution degree 3

- Installation category II
