Installing and Wiring

Installation Environment

Conditions

• Install in a waterproof and dustproof control panel.

• Install at the place without continuous shock or vibration.

• Keep out of the direct rays of the sun.

• No dew caused by sudden temperature variation.

• Keep the ambient temperature from 0 to 55 oC.

Works

• In case of making bolthole or wiring, keep a PLC from dust and dregs.

• Install at the place to operate easily.

• Do not install together with high-voltage device and same panel.

• The distance between ducts and modules is to be over 50 oC.

• Ground at the place where the environment of noise is good.

Cautions

• Do not drop or shock.

• Do not separate a PCB from a case. That may be the reason of breakdown.

• In case of wiring, take care that dregs come into the top of a module. If there are, remove them.

• Mount or take out a module after turning off power.

Safety Precautions

• Use separate cables for AC and outside input signals of a TC converter module to keep from the serge or the induced noise occurring from the AC.

• Select the wire, considering ambient temperature, allowable current. AWG22(0.3 mm2) or more is recommended as the thickness of the wire.

• Keep the wire out of heat-generating device, toxic substance and oil. They may cause breakdown or malfunction.

• Make sure polarity before inputting analog value to a terminal block.

• The wiring together with high-voltage line or power line may cause malfunction or breakdown.

Example of Wiring
Measured values are inputted to all the channels grouped as Terminal 7-8, 9-10, 11-12, 13-14.

Open	Open Cable is to be used as conducting wires. Connect the shield part of a wire to FG terminal(No. 18) and ground it. Connect RJC to Terminal 1, 3 and 5.
