Optional DC Power Cable
The power cable is a 14.5-foot, 18 AWG stranded
cable. The connector is terminated at one end with a
6-position connector. The other end of the cable is
terminated with a bare wire that should be connected to a
dc power source. Figure D-11 shows the wire colors. The
power source can be either a single source of +24 Vdc or
up to two sources of –48 Vdc (A and B). You cannot
connect +24 Vdc and –48 Vdc to the same unit. See the
installation instructions in Chapter 2, Installation.
