Notes: A single 110 VAC surge suppressor protects the whole rack. The RF Amp has its own 110 VAC power supply. Everything else runs off a single 10-16 VDC, battery-backed power supply/charger. The controller in the power amp chassis runs off the 10-16 VDC (not the 110 VAC). This power supply architecture avoids the need for a battery-backed AC inverter. Both antennas need lightening/EMP protection. The various comms connections need appropriate protection. Connections within chassis are not shown. The power supply/charger may have status that needs to be connected to the PC.
