• Do not apply excessive power when connecting or disconnecting the connectors of the
product.
• Switch or circuit breaker should be installed nearby users for convenient control.
• Do not use the unit for other purpose (e.g. voltmeter, ammeter), but temperature
controller.
• When changing the input sensor, turn off the power first before changing.
After changing the input sensor, modify the value of the corresponding parameter.
• Power supply should be insulated and limited voltage/current or Class 2, SELV power
supply device.
• 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.
• 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.
• 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.
• Make sure that power supply voltage reaches to the rated voltage within 2 sec after
supplying power.
• Do not wire to terminals which are not used.
• Install DIN rail vertically from the ground.
• 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 II
