7.0 Installation, continued
Connect the RF drop according to the diagram below. The RF drop must have a properly installed ground
block in the power supply enclosure. Recommended downstream RF level is 0 dBmV. Connect any other
front panel connections at this time (e.g. battery strings, tamper switch).
Install a grounded surge suppressor (Alpha P/N 162-028-10 or equivalent) to protect
equipment from overvoltage.
