SC 4812ET RF Cabinet
SC 4812ET Power Cabinet
If the SC4812ET is installed in an indoor location, Adequate ventilation
must be available to dissipate heat loads of 7,500 Watts (25,600 Btu/hr)
for the RF Cabinet and 3,000 Watts (10,300 Btu/hr) for the Power
Cabinet (a total of 10,500 Watts; 35,900 Btu/hr), and maintain a
maximum temperature of no greater than 50 Deg C (122 Deg F).
The ground system resistance must be less than 10 Ohms, with 5 Ohms
or less being the goal, see "Grounding Guidelines for Cellular Radio
Installations" Motorola P/N 68P81150E62 for details.
The Power Cabinet is rated at 130 Amps (100 Amps continuous/130
non–continuous in the range of 208–240 VAC). Maximum cable size
that can be accommodated is 300 kcmil. Cable sizing should be
determined by Local Electric Codes, using 90 Deg C rated conductors,
and derating for 50 Deg C operation. Motorola recommends not less
than #2/0 AWG (#1 BSWG; 50 mm
to the power pedestal, with an associated power pedestal breaker size of
150 Amps for a single Power Cabinet.
