Precautions
1. Installation Precautions
Caution
This instrument is intended to be used under the following environmental conditions
(IEC61010-1): Overvoltage category , Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
• A minimum of dust, and an absence of corrosive gases
• No flammable, explosive gases
• No mechanical vibrations or shocks
• No exposure to direct sunlight, an ambient temperature of -10 to 55 (14 to 131 ) that does not
change rapidly, and no icing
• An ambient non-condensing humidity of 35 to 85%RH
• No large capacity electromagnetic switches or cables through which large current is flowing
• No water, oil or chemicals or where the vapors of these substances can come into direct contact with
the unit
• Take note that the ambient temperature of this unit – not the ambient temperature of the control panel –
must not exceed 55 (131 ) if mounted through the faceof a control panel, otherwise the life of
electronic components (especially electrolytic capacitors) may be shortened.
※Avoid setting this instrument directly on or near flammable material even though the case of this
instrument is made of flame-resistant resin.
Caution
Procedures which may lead to dangerous conditions and cause death or serious
injury, if not carried out properly.
Procedures which may lead to dangerous conditions and cause superficial
to medium injury or physical damage or may degrade or damage the product, if
not carried out properly.

2. Wiring Precautions
Caution
• Do not leave wire remnants in the instrument, as they could cause a fire or malfunction.
• Use the solderless terminal with an insulation sleeve in which the M3 screw fits when wiring the
instrument.
• The terminal block of this instrument is designed to be wired from the left side. The lead wire must be
inserted from the left side of the terminal, and fastened with the terminal screw.
• Tighten the terminal screw using the specified torque. If excessive force is applied to the screw when
tightening, the terminal screw or case may be damaged.
• When using a terminal cover for the KT4R, pass terminal wires numbered 7 to 12 into the holes of the
terminal cover.
• This instrument does not have a built-in power switch, circuit breaker and fuse.
It is necessary to install a power switch, circuit breaker and fuse near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250 V AC, rated current 2A)
• For the KT4R with a 24 V AC/DC power source, do not confuse polarity when using direct current (DC).
• 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 a thermocouple and compensating lead wire according to the sensor input specifications of this
controller.
• Use the 3-wire RTD according to the sensor input specifications of this controller.
• For DC voltage input, (+) side input terminal number of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC differs
from that of 0 to 1 V DC.
Model Terminal Number
KT4R 9: (+) side of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC
10: (+) side of 0 to 1 V DC
KT8R, KT9R 21: (+) side of 0 to 5 V DC, 1 to 5 V DC, 0 to 10 V DC
22: (+) side of 0 to 1 V DC
• When using a relay contact output type, externally use a relay according to the capacity of the load to
protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires.
3. Operation and Maintenance Precautions
Caution
• It is recommended that AT be performed on the trial run.
• Do not touch live terminals. This may cause electric 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 to electric shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)
• As the display section is vulnerable, do not strike or scratch it with a hard object or put pressure on it.

The torque is 0.15 N•m.
For the KT8R, KT9R, the torque should be 0.1 N•m.
3.3.1 How to MounttheUnit
KT4R
Mount the controller vertically to the flat, rigid panel to ensure it adheres to the Water-proof/
Dust-proof specification (IP66).
If the lateral close mounting is used for the controller, IP66 specification (Water-proof/Dust-proof)
may be compromised, and all warranties will be invalidated.
Mountable panel thickness: 1 to 5 mm
(1) Insert the controller from the front side of the control panel. (Fig. 3.3.1-1)
If the Water-proof/Dust-proof specification (IP66) is not necessary, the rubber gasket may be
removed (please keep in mind the warranty is void if the rubber gasket is removed).
(2) Insert the mounting frame until it comes into contact with the panel, and fasten with screws.
Tighten screws with one rotation upon the screw tips touching the panel. (Fig. 3.3.1-2)
The torque is approximately 0.15 N•m.

3.3.2 How to Remove the Mounting Frame and Unit
KT4R (Fig. 3.3.2-1)
(1) Turn thepower to the unit OFF, and disconnect all wires before removing the mounting frame.
(2) Insert a flat blade screwdriver between the mounting frame and unit ( 1).
(3) Slowly push the frame upward using the screwdriver ( 2), while pushing the unit toward the
panel ( 3).
(4) Repeat step (2) and slowly push the frame downward using the screwdriver for the other side.
The frame can be removed little by little by repeating these steps.
