Wire the transmitter to the sensor
1.
Connect the cable to the core processor as described in the sensor documentation.
2.
Feed the wires from the sensor through the conduit opening.
3.
Connect wires to the appropriate terminals on the mating connector.
Important
Never ground the shield, braid, or drain wire(s) at the transmitter.
Tip
You may find it easier to unplug the mating connector to connect the wires. If you do so,
remember to firmly reseat the mating connector and tighten the mating connector screws so
that the mating connector cannot accidentally come loose.
