Meaning of Warning Message on Model Label

CautionIf do not handle this instrument correctly, may suffer minor or moderate injury or property damage
due to fire, malfunction, or electric shock. Please read this manual carefully and fully understand it
before using it.

Wiring Precautions

Caution• Do not leave bits of wire in the instrument, because they could cause a fire and malfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation sleeve in which an
M3 screw fits.
• The terminal block of this instrument has a structure that is wired from the left side. Be sure toinsert the lead wire into the terminal of the instrument from the left side and tighten the terminal
screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw
when tightening, the screw or case may be damaged.
• Do not pull or bend the lead wire with the terminal as the base point during or after wiring work. It
may cause malfunction.
• This instrument does not have a built-in power switch, circuit breaker and fuse. It is necessary to
install an appropriate power switch, circuit breaker and fuse near the instrument.
• When wiring the power supply (24 VDC), do not confuse the polarities.
• Do not apply a commercial power source to the sensor which is connected to the input terminal nor
allow the power source to come into contact with the sensor.
• Use the thermocouple and compensation lead wire that match the sensor input specifications of
the instrument.
• Use a RTD of 3-conducting wire type that meets the sensor input specifications of this instrument.
• When using a relay contact output type, externally use a relay according to the capacity of the loadto protect the built-in relay contact.
• Separate the input line (thermocouple, RTD, etc.) from the power line and load line.

Operation and Maintenance Precautions

Caution• It is recommended that auto-tuning (AT) be performed on the trial run.
• Do not touch live terminals. This may cause electrical shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal or cleaning. Working
on or touching the terminal with the power switched ON may result in severe injury or death due toelectrical shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the panel part is vulnerable, be careful not to put pressure on, scratch or strike it with a hard
object.

Compliance with Safety Standards

Caution• Use the recommended fuse as described in the instruction manual.
• For analog input- When inputting voltage or current, set the input type to match the input specification.
- Do not use for measurement of circuits that fall into measurement categories II, III, or IV.
- Do not use for measurement of objects to which a voltage exceeding 30 Vrms or 60 V DC isapplied.
• If the instrument is used in a manner not specified by the manufacturer, the protection provided by
the instrument may be impaired.
• Use equipment that is reinforced-insulated or double-insulated from the primary power supply forexternal circuits connected to this instrument.
