Sensor Field Wiring

Figure 4 contains diagrams for connecting, at the field junction box, cables from the sensor to cables from the
console. Check diagrams closely for polarity requirements.

Sealing Field Connections

WIRING RUN THROUGH RIGID CONDUIT

1. Pull the wires from the sensor into the junction box. Pull the two wires from the console through the seal-off
box, the conduit attaching the junction box to the seal-off box and into the junction box.
2. Using wire nuts, connect the two wires from the sensor to the two wires coming from the console. Be sure to
observe color codes or tags when making these connections so that the sensor outputs are attached to the
correct terminals in the console and that polarity is maintained when required.
3. Seal wire nuts with epoxy sealant following the instructions in Figure 5.
