Be sure to wire in accordance with "2.5 Terminal layout."
Use a crimp-type terminal that matches an M3.5 screw and is no wider than 7 mm.
For thermocouple input, use a compensating conductor that matches the type of thermocouple.
Arrange so that external resistance does not exceed 100
Ω
.
For R.T.D. input, resistance for lead wires should be a maximum of 5
Ω
per wire. All 3 wires should have the same resistance.
Input signal wires must not be accommodated with a strong electric circuit in the same conduit or duct.
Using shielded wiring (single point grounding) is effective for static induction noise.
Making input wiring short and twisting at regular intervals is effective for electromagnetic induction noise.
For power supply, use wiring or cable with sectional area of at least 1 mm² that offers the same performance as 600V vinyl
insulated wiring.
The ground wire should be at least 2 mm² and the ground resistance should not exceed 100
Ω
.
The symbol
indicates the location of the function ground terminal. Ground if possible to avoid the effect of noise, etc.
Securely fasten the terminal element screw.
Fastening torque: 1.1N · m (11kgf · cm)
Noise filter
If the instrument appears to be easily affected by power supply noise, use a noise filter to prevent malfunctioning.
Mount the noise filter on the grounded panel and make the wire connection between the noise filter output and power line
terminals of the indicator as short as possible.

Do not connect an input other than the stipulated input to the terminals.
