5.2 Wiring for Detector Output
This wiring enables the converter to receive cell output from the detector, output from a
thermocouple and a reference junction compensation signal. Install wires that allow for 10 Ω of
loop resistance or less. Keep detector wiring away from power wiring.

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.
5.2.1 Cable Specifications
Basically, PVC insulated PVC sheathed cable (6-core) is used for this wiring. When the ambient
temperature of the detector exceeds 80 °C, install a terminal box, and connect with the detector
using six-piece 600 V silicon rubber insulated glass braided wires.
