5.  How to Connect Wires

WARNING 

•  Wiring work must be carried out by a person with basic electrical 

knowledge and practical experience.

•  Be sure to turn OFF the power supply to the controller before 

wiring to avoid an electric shock. Use a tester or similar device to 

ensure that no power is being supplied to a cable to be connected.

•  For the wiring cable, the temperature rating is 75 °C or more.

•  As a safety measure, always install a circuit breaker (an IEC 

60947-compatible product, 5 A, 100 V or 220 V AC) in an easily 

accessible location near the instrument. Moreover, provide 

indication that the switch is a device for turning off the power to 

the instrument.

•  Install the power cable keeping a distance of more than 1 cm 

from other signal wires.

•  The power cable is required to meet the IEC standards concerned or 

the requirements of the area in which the instrument is being installed.

•  Wiring should be installed to conform to NEC (National Electrical 

Code: ANSI/NFPA-70) or the wiring construction standards in 

countries or regions where wiring will be installed.

• Since the insulation provided to each relay output terminal is 

Functional insulation, provide Reinforced insulation to the 

external of the device as necessary. (Refer to the drawing below.)

CAUTION

•  When connecting two or more crimp-on terminal lugs to the 

single terminal block, bend the crimp-on terminal lugs before 

tightening the screw.

•  Note that the wiring of two or more crimp-on terminal lugs to the 

single high-voltage terminal of the power supply and relay, etc. 

does not comply with the safety standard.

CAUTION

•  Provide electricity from a single-phase power supply. If the 

power is noisy, install an isolation transformer on the primary 

side, and use a line filter on the secondary side. When measures 

against noise are taken, do not install the primary and secondary 

power cables close to each other.

•  If there is a risk of external lightning surges, use a lightning 

arrester etc.

•  For TC input, use shielded compensating lead wires for wiring. 

For RTD input, use shielded wires that have low conductor 

resistance and cause no significant differences in resistance 

between the three wires.

•  Since the control output relay has a life span (resistance load of 

100,000 times), use the auxiliary relay to perform ON/OFF control. 

•  The use of inductance (L) loads such as auxiliary relays, motors 

and solenoid valves causes malfunction or relay failure; always 

insert a CR filter for use with alternating current or a diode for 

use with direct current, as a spark-removal surge suppression 

circuit, into the line in parallel with the load.

•  After completing the wiring, the terminal cover is recommended 

to use for the instrument.
