Power Supply Wiring For 1066-FF
Power Supply Wiring
Run the power/signal wiring through the opening nearest TB2. Use shielded cable and ground the
shield at the power supply. To ground the transmitter, attach the shield to TB2-3.
Note: For optimum EMI/RFI immunity, the power supply/output cable should be shielded and
enclosed in an earth-grounded metal conduit. Do not run power supply/signal wiring in the same
conduit or cable tray with loop power lines. Keep power supply/signal wiring at least 6 ft (2 m)
away from heavy electrical equipment.

Figure 4-4 shows a 1066PFF being used to measure and control pH and chlorine levels in drinking
water. The figure also shows three ways in which Fieldbus communication can be used to read
process variables and configure the transmitter.
