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 of loop resistance or less. Keep detector wiring away from power wiring.
Separate signal and power wiring.

Note
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.
Basically, PVC sheathed PVC insulated cable (six 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
wire.
