WIRING
3.2 POWER SUPPLY WIRING FOR
MODEL XMT-P-FF
3.2.1 Power Supply Wiring. Refer to Figure 3-3 and
Figure 3-4.
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 sup-
ply/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 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.
