3. WIRING
3.1 Wiring Cautions
! For thermocouple input, use the appropriate compensation wire.
! For RTD input, use low resistance lead wire with no difference in resistance between the three lead wires.
! To avoid noise induction, keep input signal wire away from instrument power line, load lines and power lines of other electric
equipment.
! If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
- Shorten the distance between the twisted power supply wire Instrument power
Twist these leadwires
pitches to achieve the most effective noise reduction.
IN OUT Instrument
- Always install the noise filter on a grounded panel. Minimize Noise filter power
the wiring distance between the noise filter output and the terminals
Shorten distance between Minimize
instrument power supply terminals to achieve the most pitches distance
effective noise reduction.
- Do not connect fuses or switches to the noise filter output wiring as this will reduce the effectiveness of the noise filter.
! Power supply wiring must be twisted and have a low voltage drop.
! About four seconds are required as preparation time for contact output every time the instrument is turned on. Use a delay relay
when the output line, is used for an external interlock circuit.
! This instrument is not furnished with a power supply switch or fuses. Therefore, if a fuse or power supply switch is required, install
close to the instrument.
- Fuse type: Time-lag fuse
- Recommended fuse rating: Rated voltage 250 V Rated current: 1 A
! For the current input specification, a resistor of 250 " (#0.02 % #10 ppm, 0.25 W or more) must be connected between the input
terminals. This resistor must be provided by the customer.
! Use the solderless terminal appropriate to the screw size.
- Screw size: M3 x 6
- Recommended tightening torque: 0.4 N m [4 kgf cm]
! For an instrument with 24 V power supply, supply power from a SELV circuit.

two lugs are connected to one communication terminal for the use of multidrop connection, much care should be exercised not to
touch the power supply terminals with the lugs. 12 % 12 %
