• Do not leave bits of wire in the KT7 series when wiring, because they could cause fire or malfunction. 
• Insert the connecting cable into the designated connector securely. Otherwise malfunction may occur due
  to imperfect contact. 
• Connect the AC power wire to the designated terminal as is written in this instruction manual, otherwise 
  it may burn and damage the KT7 series. 
• Tighten the terminal screw with the specified torque. Excessive force could damage the terminal screw 
  and deface the case. 
• Use a thermocouple and compensating lead wire that corresponds to the sensor input specification of this unit. 
• Use the 3-wire RTD that corresponds to the sensor input specification of this unit. 
• When using DC voltage and current input types, do not confuse the polarity when wiring. 
• For a 24V AC/DC power source, do not confuse polarity when using direct current (DC). 
• Keep input wires (Thermocouple, RTD, etc) away from power source and load wires to avoid external 

interference. 

• To prevent the unit from harmful effects of the unexpected level noise, it is recommended that a surge 

absorber be installed between the electromagnetic switch coils. 

• This unit does not have built-in power switch, circuit breaker or fuse. Therfore, it is necessary to install 

them in the circuit near the external unit. 

(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A) 

Note: Tighten the terminal screw properly referring to the table below.

(1) This alarm is not available for detecting heater current 

(2) This alarm is not available for detecting 3-phase 

heater current. 

(3) Use the current transformer (CT) provided, and pass one 

lead wire of the heater circuit into the hole of the CT. 

(4) When wiring, keep CT wire away from AC sources 

or load wires to avoid the external interference.
