74. WiringWarningTurn the power supply to the instrument off before wiring.Working on or touching the terminal with the power switched on may result in severe injuryor death due to Electric Shock.• TC : Thermocouple input terminals• RTD : RTD input terminals• DC : DC current, DC voltage input terminalsFor DC current input type, connect 50shunt resistor (sold separately) betweeninput terminals.• OUT1 : Control output or Heating output (Heating/Cooling control option) terminals• POWER SUPPLY: Power terminals• EV1/OUT2: Event output 1 or Cooling output(Heating/Cooling control option) terminals• EV2 : Event output 2 terminals• DI : DI (Digital input) terminalsThree DI functions: SV1/SV2 external(Fig. 4-1) selection function, OUT/OFF (RUN/STOP)external selection and Timer function• RS-485: Serial communication terminalsNotice• To extend a thermocouple’s lead wire, be sure to use a compensating lead wire in accordance withthe sensor input specification. (If any other compensating lead wire is used, a temperature indicationerror 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 isnecessary to install them in the circuit near the external controller.(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• When using a 24V DC for the power source, do not confuse polarity.• When using a relay contact output type, externally use a relay according to the capacity ofthe load to protect the built-in relay contact.• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wiresto avoid external interference.• Do not apply a commercial power source to the sensor connected to the input terminal norallow the power source to come into contact with the sensor.Lead wire solderless terminalUse a solderless terminal with an insulation sleeve in which an M3 screw fits as shown below.The torque should be 0.63N•m.Solderlessterminal Manufacturer Model TighteningtorqueNichifu Terminal Industries CO., LTD.
