SECTION 4: INSTALLATION OVERVIEW
Input Power Requirements
The Nucleus Advanced Control Paging Station is equipped with an ac power supply (90 to 280 V rms, 50 to 60 Hz) or a dc-dc power supply (21 to 34.5 V dc or 41 to 72 V dc). All ac power supplies feature automatic range and line frequency selection.
It is recommended that a standard 3-wire grounded electrical outlet be used as the ac source. For a 125 W station and a nominal 110 V ac input, the ac source must supply 5 amperes and should be protected by a circuit breaker rated at 15 A. For a nominal 220 V ac input, the ac source must supply approximately 2.5 A.
For a 900 MHz, 300 W station, two power supplies are used, which draw a total of 13 A. Use a circuit breaker rated at 20 A.
For a 24 V dc or 48/60 V dc source, appropriate cabling from the dc power source to the Backplane (located at rear of station) is supplied.
