User-supplied 4-wire cable must meet the following requirements:
• Twisted pair construction.
• Applicable hazardous area requirements, if the core processor is installed in a
hazardous area.
• Wire gauge appropriate for the cable length between the core processor and the
transmitter.

3.3 Wire the transmitter to the sensor
1. Connect the cable to the sensor-mounted core processor as described in the sensor
documentation.
2. Feed the wires from the sensor through the conduit opening on the transmitter.
3. Connect wires to the appropriate terminals on the mating connector.
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.
