CAUTION
If shielded cables cannot be used between the detector and the terminal box, for example,
when heat-resistant wiring is used, locate the detector and the terminal box as close together as
possible.
Cable Specifications
Basically, a cable (6-core) that withstand temperatures of at least 80°C is used for this wiring.
When the ambient temperature of the detector exceeds 75°C, install a terminal box, and connect
with the detector using six-piece 600 V silicon rubber insulated glass braided wires.
/CJ Option Specifications
When the /CJ option is specified, connecting the supplied cold junction compensation element
to the CJ (+) and CJ (-) terminals of the converter, and connecting the tip to the FG terminal (see
