(1) Hook (1) of KT7 series on the upper side of the DIN rail. (Fig. 3.4-1)
(2) Making the (1) part of the KT7 series as a support, fit the lower part of the KT7 series to the DIN rail.
KT7 series will be completely fixed to DIN rail with a “Click” sound. (Fig. 3.4-1)

4. Wiring connection
Warning
Turn the power supplied to the instrument OFF before wiring or checking it.
Working or touching the terminal with the power switched ON may result in
Electric Shock
causing severe injury or death.
Caution
•
Do not leave wire chips in the KT7 series when wiring, because they could cause fire, malfunction and
trouble.
•
Insert the connecting cable into the designated connector securely. Otherwise malfunction due to
imperfect contact may occur.
•
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. If not, it may damage the terminal screw and deform
the case.
•
Use
thermocouple
and compensating lead wire that fit 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.
•
When using a 24V AC/DC for the power source, do not confuse the polarity when it is 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)
