SAFETY PRECAUTIONS
(Be sure to follow the precautions described below to prevent injury or accidents.)
The safety precautions are classified into categories: “Warning” and “Caution”.
Warning: Procedures which may lead to dangerous conditions and cause death or
serious injury, if not carried out properly.
Caution: 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.

2.3 Panel cutout (Unit: mm)
• When using this controller on occasions which serious injury would be expected to
occur or when damage is likely to expand or proliferate, make sure to take safety
measures such as installing double safety structures.
• Do not use this controller in an environment with flammable gases, or it may cause
explosion.

be invalidated.
2.4 Mounting and removal to/from the control panel
How to mount the KT4H/B (Fig.2.4-1, Fig.2.4-2)
Mount the controller vertically to ensure it adheres to the Dust-proof/Drip-proof specification (IP66).
Mountable panel thickness: Within 1 to 5mm
(1) Insert the controller from the front side of the panel.
(2) Insert the mounting frame until the frame tips come into contact with the panel, and fasten with screws.
Tighten screws with one rotation upon the screw tips touching the panel. Torque: 0.05 to 0.06N•m.
How to remove the mounting frame (Fig.2.4-3)
(1) Turn the power to the unit OFF, and disconnect all wires before removing the mounting frame.
(2) Insert a flat blade screwdriver between the screw 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.
• Fasten the electric wire with the terminal screws securely. Imperfect connection may
cause abnormal heating or fumes.
• Use this controller according to the rating and environmental conditions. Otherwise
abnormal heating or fumes may occur.
• Do not touch the terminals while the power is supplied to the controller, as this may
cause electric shock.
• Do not disassemble or modify the controller, as this may cause electric shock or fumes.
Caution
• This instrument should be used in accordance with the specifications described in these
instructions. If it is not used according to the specifications, it may malfunction or cause fire.
• Be sure to follow the warnings, cautions and notices. Not doing so could cause serious
injury or accidents.
• The contents of this booklet are subject to change without notice.
• This instrument is designed to be installed in a control panel. If not, measures must be
taken to ensure that the operator cannot touch power terminals or other high voltage
sections.
• Be sure to turn the power supply to the instrument OFF before cleaning this instrument.
• 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.
• Any unauthorized transfer or copying of this document, in part or in whole, is prohibited.
• Matsushita Electric Works, Ltd. is not liable for any damages or secondary damages
incurred as a result of using this product, including any indirect damages.

• 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 by
the terminal screw. The torque is approximately 0.63N•m.
• When using a terminal cover (AKT4H801), pass terminal wires numbered 7 to 12
into the holes of the terminal cover. See (Fig. 3-2).
• To extend a thermocouple’s lead wire, be sure to use a compensating lead
wire in accordance with the sensor input specification. (If any other compensating lead wire is used, a temperature indication error may be caused.)
• Use the 3-wire RTD which corresponds to the input specification of this controller.
• This controller does not have a built-in power switch, circuit breaker or fuse.
Therefore, it is necessary to install them in the circuit externally, near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)
• For a 24V AC/DC power source, do not confuse polarity when using direct current (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 to avoid external interference.
• If Alarm 2 and Heater burnout alarm are added together, they (EVT2) utilize
common output terminals.
Lead wire solderless terminal
When using a Terminal cover
Use a solderless terminal with an insulation sleeve in which an M3 screw
fits as shown below. The torque is approximately 0.63N•m.

This alarm is not usable for detecting heater current under phase control.
Use the current transformer (CT) provided, and pass one lead wire of the
heater circuit into the hole of the CT. (Fig.3-4) When wiring, keep the CT
wire away fromAC sources or load wires to avoid the external interference.
In the case of 3-phase, pass any 2 lead wires of R, S, T into the CT,
and connect them with CT1 (13, 14) and CT2 (14, 15) terminals.

In order to set each value of P, I, D and ARW automatically, the auto-tuning process should be made to
fluctuate to obtain an optimal value. Sometimes the auto-tuning process will not fluctuate if auto-tuning
is performed at or near room temperature. Therefore auto-tuning might not finish normally.
