The power supply will enter thecabinet via conduit located at the rear <strong>of</strong> the cabinet.The power cabinet will consist <strong>of</strong> the following:• AC and earth terminations;• transfer switch (mains and generator positions);• surge protection;• general purpose outlet;• low voltage disconnect;• rectifier modules;• controller/supervisory module;• DC distribution rack; and• batteries (with the capability <strong>of</strong> providing a minimum <strong>of</strong> four hours’ back-up).MonopoleThe antennas will be connected installed on an existing 30 metre high MetroNet pole in the railcorridor approximately 38 metres from the eastern side <strong>of</strong> the track. Two Argus antennas will bemounted 24 metres above the ground with azimuths <strong>of</strong> 10° and 195°. The antennas will beinstalled to have a zero degree tilt, but will be able to be remotely adjusted to different degrees<strong>of</strong> tilt, without the need to climb the monopole <strong>for</strong> such adjustments.3.1.3 Power SupplyThe supply to the Wollongong Yard power cabinet will be via an existing distribution board in theWollongong Communications Room.
