᜸ 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, fire or economic loss.
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 dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in fire.
03. Keep metal chip, dust, and wire residue from flowing into the unit.
Failure to follow this instruction may result in fire or product damage.
04. Do not disconnect connector or power, when the product is operating.
Failure to follow this instruction may result in fire or malfunction.
Cautions during Use
• Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected
accidents.
• 24 VDCᜡ power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
• Use only designated connector and do not apply excessive power when connecting
or disconnecting the connectors.
• Keep away from high voltage lines or power lines to prevent inductive noise.
In case installing power line and input signal line closely, use line filter or varistor at
power line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high
frequency noise.
• Do not connect or disconnect the USB cable and RS485 cable quickly and repeatedly
while communicating.
It may cause damage or malfunction of the product and PC.
• After supplying power, connect with the communication output product. When
disconnect, communication output product first and power last.
• When connecting multiple SCM-WF48 units to a PC, number of COM port goes up in
sequential order and it takes some time to identify and assign number of COM port.
• When connecting the RS485 communication output product, connect the
terminating resistance (120Ω, 1% (F) grade chip resistance, 1/4W) at each end of the
communication cable.
• Use twist pair wire for RS485 communication. If not, use A(+) and B(-) cables in the
same length.
• Use USB cable of designated standard, and do not use extension cable.
