SECTION 4.00 POWER-UP TESTS
4.01General. The SATURN IIE System makes use of dis-
tributed power in the equipment cabinet. Several power sup-
plies are used in the system. These power supplies provide
+5Vdc, -SVdc, +12Vdc, -12Vdc, -48Vdc, 90Vac-20Hz ringing
voltage and message waiting voltage, from a 11OVac 60Hzinput power source. After satisfactorily performing the ground
tests 
indicaied in Section 3.00, the...
