Power Input Requirements: 12 to 28VDC Supply
External DC power supply must provide 12 to 28VDC (10 to 30VDC full input power
range) at 6 Watts minimum.
(With 12VDC power, the F-5500 can use up to 500mA. With 24VDC power, the F-5500
can use up to 250mA.)
A 20 Watt or greater power supply is recommended to ensure it can provide enough
current under all temperature, ventilation and power on conditions.
The enclosure must be properly grounded with a quality earth ground. Sixteen (16)
gauge, stranded wire, is recommended for power and earth ground.
