3) The external covering material must be selected appropriately for the installation environment.
4) If there are outdoor wiring sections, do not use glass sheathing. Humidity may reduce
insulation resistance and cause measuring errors.
5) Cables shall be protected from damage such as breakage or cutting by the surrounding
environment.
6) Exercise caution to prevent folding or knitting of cable.
6.2 Precaution for wiring
1) Make sure to cut off power before wiring product with an explosion proof grade.
2) Connect thermocouples (TC) after checking polarity (+/-). Wire resistance temperature detectors
(RTD) after disconnecting the A/B/B (3-wire) terminal.
3) Attach the end of the compensation wire and cable to the terminal block using crimp terminals.
Tightly fasten the screws.
4) When wiring to a transmitter, adhere to the wiring instructions given in the user manual for the
transmitter.
5) For equipment with an explosion proof grade, make sure the cover does not open during
operation. Tighten the locking apparatus.
6) Earthing
- Use aluminum earthing terminals to prevent corrosion.
- Use 304SS earthing bolts.
- Use spring washers to prevent loosening of the earthing terminals.
- When using external earthing terminals, check the connectors and use an appropriate earthing line.
7) After making the connections, inspect to ensure that the power supply and signal cables have
been connected properly.
