13Notice• The terminal block of KT9 series is designed to be wired from the left side.The lead wire must be inserted from the left side of the terminal, and fastenedwith the terminal screw.• Dotted lines show options.• If A2 (option) and Heater burnout alarm (option) are applied together, useterminals 12-13 for A2, and 9-10 for the Heater burnout alarm.• If the Heating/Cooling control (option) and Heater burnout alarm (option) areapplied together, use terminals 9-10 for the Heating/Cooling control, and 12-13for the Heater burnout alarm.• When only Heater burnout alarm option is applied, use terminals 9 and 10.Lead wire solderless terminalUse a solderless terminal with an insulation sleeve in which an M3 screw fits as shownbelow.(Fig. 4.1-2)4.2 Wiring examplesNotice• To extend a thermocouple’s lead wire, be sure to use a compensating lead wire inaccordance with the sensor input specification. (If any other compensating lead wireis used, a temperature indication error may be caused.)• Use the 3-wire RTD according to the sensor input specifications of this controller.• This controller does not have built-in power switch, circuit breaker or fuse.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, use a relay externally according to thecapacity of the load to protect the built-in relay contact.• When wiring, keep the input wire (Thermocouple, RTD, etc.) away from AC sourcesor load wires to avoid external interference.• Use a thick wire (1.25 to 2.0mm2) for grounding.Solderlessterminal Manufacturer Model Tightening torqueNichifu Terminal Industries CO.,LTD.
