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 the unit on DIN rail or panel to use.
Failure to follow this instruction may result in fire.
04. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire.
05. Do not connect, repair, or inspect the unit while connected to a power
source.
Failure to follow this instruction may result in fire.
06. 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 a DC relay, remove surge by using a diode
or varistor.
• Use the product after 3 sec of the power input.
• 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.
• Since external disturbance light (sunlight, fluorescent lighting, etc.) can cause product
malfunction, use the product with a light shield or slit.
• When sensing an object with the maximum sensitivity, an error of sensing distance
can occur due to the deviation of each feature.
• Turn off the power of the fiber optic amplifier before installation or removal.
• When installing the fiber optic unit, check the bend radius of each unit written on the
product manual. If the installed unit that has the bend radius under the rated range,
causing optical loss so the sensing distance is shortened.
• Be sure not to scratch the surface of the fiber optic unit.
• Do not pull the cable of the fiber optic unit that is connected to the amplifier.
• 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 III
