Refer to
Figure 4-2
.
Run the power/signal wiring through the opening nearest TB-2.
For optimum EMI/RFI protection:
1. Use shielded power/signal cable and ground the shield at the power supply.
2. Use a metal cable gland and be sure the shield makes good electrical contact with the gland.
3. Use the metal backing plate when attaching the gland to transmitter enclosure. The
power/signal cable can also be 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.
