Installing antennas and IRFUs Chapter 5: Installation
5-76
phn-2513_004v000 (Oct 2012)
Connecting power to the IRFU
Connect the power supply cable to the IRFU (Figure 93). Check that the power connector
screws are tight enough to hold the power cable securely in place.
For EMI Class B compliance, a 10 AWG braided shielded power cable with drain wire and
foil is recommended.
If a battery is being used to supply power, connect the ‘common’ battery terminal to the
main electrical grounding system (not directly to the building grounding system).
