Warning
Improper wiring to the equipment may cause a failure, such as fire. Upon completion of wiring,
ensure to verify the proper wiring before turning on electricity.
Do not turn on electricity until all wiring is complete. Do not touch portions of high voltages such as
power supply terminals, as an electric shock may be resultant.
Install appropriate protective circuits externally if a failure or abnormality of the equipment may seriously affect
related systems.
Do not use the equipment out of the specified range, as it may fail or catch fire.
Do not under any circumstance to modify or disassemble the equipment, as a failure may be caused, resulting
fire or an electric shock.
Do not use the equipment in ambience of flammable or explosive gases.
Caution
Do not use the vacant terminals for wiring.
Do not use a pointed object to operate keys.
Do not turn on the power supply until wiring is fully complete in order to prevent an electric shock, failure or malfunctioning. For replacing a component connected on the equipment, ensure to turn off
the power supply. For turning back on the power supply, do so after all wiring is complete.
Ensure not to trap heat in the space surrounding the equipment in order to provide sufficient heat release.
Do not put a metal piece or similar inside the equipment. A fire, an electric shock or failure may be caused.
The equipment is designed for instrumentation. For its use in environments of high voltages or intense noises,
take appropriate measures on the side of user’s equipment.
The equipment is designed for controlling physical values, such as temperatures, on general industrial facilities.
Do not use it for subjects of control that may seriously affect human life.
Turn off the power supply before cleaning the equipment, and wipe it with a soft dry cloth. Do not use
thinners, as they may cause deformation or discoloration of the equipment.
The equipment may cause radio disturbances in domestic settings. User is required to take appropriate
measure.
Ensure to tighten terminal screws at specified torque. Insufficient tightening the screws may cause an electric
shock or fire.
Ensure to observe precautions listed in this manual for the use of the equipment.
Reprinting or duplicating this manual is prohibited.
This manual may be revised without prior notice.
Important Reminder Regarding Export Trade Control Order
Please investigate the client and the purpose of his or her usage to make sure that the product will not be used as a weapon of
mass destruction (e.g., for military purposes and use in military facilities).

･Check the wiring with the operation manual to makesurethat input terminal, power terminal,option terminal, and other
suchterminalsareconnectedcorrectly.
･Uponwiring,usethecrimpedterminalthat fitswith theM3.5screw(squeezethewire intothecenter oftheterminal).
･For the connection between theresistancetemperature detectorand theproduct, use the wirewith theresistance of less
than 5Ω (per wire).
･For the connection between the thermocouple and the product, use the prescribed compensating lead wire or the wire
itself.
･Usetheradio shield wire if theproduct is to be usednear thenoise source. Donot wire the input-output line in the same
ductor conduittube.
