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.

Cautions during Use
• Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected
accidents.
• 5 VDCᜡ, 12-24 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, earphone jack, or 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 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 (100 to 120Ω) 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.
• 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 I
