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 connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in fire or electric shock.
04. Check 'Connections' before wiring.
Failure to follow this instruction may result in fire.
05. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire or electric shock.
᜸ 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 shortening the life cycle of the product.
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 or electric shock.
03. Keep the product away from metal chip, dust, and wire residue which flow into the unit.
Failure to follow this instruction may result in fire or product damage.
Cautions during Use
• Follow instructions in 'Cautions during Use' . Otherwise, it may cause unexpected accidents.
• Check the polarity of the terminals before wiring the temperature sensor.
For RTD temperature sensor, wire it as 3-wire type, using cables in same thickness and length
and for thermocouple (CT) temperature sensor, use the designated compensation wire for
extending wire.
• 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 apply excessive power when connecting or disconnecting the connectors of the
product.
• When changing the input sensor, turn off the power first before changing.
After changing the input sensor, modify the value of the corresponding parameter.
• Do not overlapping communication line and power line.
Use twisted pair wire for communication line and connect ferrite bead at each end of line to
reduce the effect of external noise.
• Use USB cable of designated standard, and do not use extension cable.
Using cable over 3m requires noise countermeasures.
• Use USB hub with the external power supply.
• When connecting multiple SCM-USU2I 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.
• Make a required space around the unit for radiation of heat.
For accurate temperature measurement, warm up the unit over 20 min after turning on the
power.
