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.
