Use long-nose pliers to remove mounting brackets from the
instrument that is installed in a narrow place or installed
tightly in a vertical position.

If specified terminal lugs other than those in not recommended dimensions are
used, terminal screws may not be tightened. In such a case, bend each solderless
terminal lug in advance and then conduct wiring. If the terminal screw is forcibly
tightened, it may be damaged.

Caution for the terminal cover usage:
If each solderless terminal lug touches the terminal cover, remove each projection
(marked *A) from the terminal cover by manually bending it in front and in rear until
broken.

For isolated device input/output blocks, refer to the following:

Up to two solderless terminal lugs can be connected to one terminal screw.

2.1 Wiring Cautions

●

For an instrument with 24 V power supply, supply power from a SELV circuit.

●

A suitable power supply should be considered in end-use equipment. The power supply
must be in compliance with a limited-energy circuits (maximum available current of 8 A).

●

For the current input specification, a shunt resistor of 250Ω ±0.02 % (Temperature
characteristics: ±10 ppm/

o

C, Specified voltage: 0.25 W or more) must be connected

between the input terminals.

●

This instrument is not furnished with a power supply switch or fuse. If a fuse or power
supply switch is required, install close to the instrument.

- Recommended fuse rating: Rated voltage 250 V, Rated current 1 A
Fuse type: Time-lag fuse

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 pitches to achieve the
most effective noise reduction.

-

Always install the noise filter on a grounded panel. Minimize the wiring distance
between the noise filter output and the instrument power supply terminals to achieve
the most 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.

Use the solderless terminal appropriate to the screw size.
Screw size: M3×7 (with 5.8×5.8 square washer)
Recommended tightening torque: 0.4 N･m (4 kgf･cm)
Applicable wire: Solid/twisted wire of 0.25 to 1.65 mm

2

Specified dimension: Refer to Fig. at the right
Specified solderless terminals:

Manufactured by J.S.T MFG CO., LTD.
Circular terminal with isolation V1.25-MS3
(M3 screw, width 5.5 mm, hole diameter 3.2 mm)

●

φ5.5 MAX

φ3.2 MIN φ5.0

5.6 mm

9.0 mm

Make sure that the any wiring such as solderless terminal is not in contact with the
adjoining terminals.

●

●

Allow approximately 5 seconds for contact output when the instrument is turned on. Use
a delay relay when the output line is used for an external interlock circuit.
