symbol represents caution due to special circumstances in which hazards may occur.

Warning Failure to follow these instructions may result in serious injury or death.

Caution

Warning

1. 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, re, or economic loss.

2. Install on a device panel to use.

Failure to follow this instruction may result in re.

3. Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in re.

4. Check 'Connections' before wiring.

Failure to follow this instruction may result in re.

5. Do not disassemble or modify the unit.

Failure to follow this instruction may result in re.

Caution

1. When connecting the power input and relay output, use AWG 20 (0.50mm
terminal screw with a tightening torque of 0.74 to 0.90N m.
When connecting the sensor input and communication cable without dedicated cable, use AWG 28 to
16 cable and tighten the terminal screw with a tightening torque of 0.74 to 0.90N m.

Failure to follow this instruction may result in re or malfunction due to contact failure.

2. Use the unit within the rated specications.

Failure to follow this instruction may result in re or product damage.

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

Failure to follow this instruction may result in re.

4. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity, direct sunlight,

radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in explosion or re.

5. Keep metal chip, dust, and wire residue from owing into the unit.

Failure to follow this instruction may result in re or product damage.

Manuals

For the detail information and instructions, please refer to user manual and user manual for communication,
and be sure to follow cautions written in the technical description (catalog, homepage).

Cautions during Use

00

1. Follow instructions in 'Cautions during Use'. Otherwise, t may cause unexpected accidents.

2. 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.
For thermocouple (CT) temperature sensor, use the designated compensation wire for extending wire.

3. 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.

4. Do not apply excessive power when connecting or disconnecting the connectors of the product.

5. Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power.

6. Do not use the unit for other purpose (e g. voltmeter, ammeter), but temperature controller.

7. When changing the input sensor, turn off the power first before changing.
After changing the input sensor, modify the value of the corresponding parameter.

8. Power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.

9. 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.

10. 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.

11. Mounting multiple devices in any way other than the specified mounting method may cause heat to build

up inside, which will shorten their service life. If there is a possibility of the ambient temperature rising to a
temperature above the specified temperature range, take steps, such as installing fans, to cool the device.
Be sure that the cooling method in not cooling just the terminal block. If only the terminal block is cooled,
measurement errors may occur.

12. Make sure that power supply voltage reaches to the rated voltage within 2 sec after supplying power.

13. Do not wire to terminals which are not used.

14. Install DIN rail vertically from the ground.

15. This unit may be used in the following environments.
