2.2.2
Wire the transmitter with HART
Procedure
1. Run the power/signal wiring through the opening nearest terminals
15 and 16.
2. Use shielded cable and ground the shield to the power supply.
3. To ground the transmitter, attach the shield to the grounding screw
on the inside of the transmitter case.
You can also use a third wire to connect the transmitter to earth
ground.
Note
For optimum EMI/RFI immunity, shield the power supply/output
cable and enclose it in an earth grounded metal conduit. Do not run
power supply/signal wiring in the same conduit or cable tray with AC
power lines or with relay actuated signal cables. Keep power supply/
signal wiring at least 6 ft. (2 m) away from heavy electrical
equipment. An additional 0-1 mA current loop is available between
TB-14 and TB-15. A 1 mA current in this loop signifies a sensor fault.
