3.3.2.1 DC Power Input
The DC Power Input is supplied through three conductor cable, Belden 9770 (RCI p/n CBL-
3_22SHLDUV.) The black conductor is DC Common and the Red conductor is +24VDC. The White
conductor is not used.
In a typical installation of the RC4500 ACU inside an AIU7, the DC Power Input cable is connected to the
+24VDC switching power supply located in the upper left corner of the enclosure back panel.
