V1.2 • 05/2006 - 7 -
1 Hook 1 of the CS4R on the upper side of the DIN rail. (Fig. 3.4-1)
2 Making 1 part of the CS4R as a support, fit the lower part of the CS4R to the DIN rail.
CS4R 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 into the CS4R when wiring, because they could cause fire, malfunction
and trouble.
• Insert the connecting cable into the designated connector securely. Not doing so could cause
malfunction due to imperfect contact.
• Connect the AC power to the designated terminal as is written in this instruction manual.
Otherwise it may burn and damage the CS4R.
• Do not apply a commercial power source to the sensor connected to the input terminal nor allow
the power source to come into contact with the sensor.
• When using a 24V AC/DC for the power source, do not confuse the polarity when it is DC.
• 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)
• Tighten the terminal screw with the specified torque. Excessive force could damage the terminal
screw and deform 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 inputs, be careful not to confuse the polarity when wiring.
• Keep input wires (Thermocouple, RTD, etc.) away from power source and load wires when wiring.
