Optional DC Power Cable (Model 3164 Only)

The dc power cable (Figure E-11, DC 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 E-11, DC Power Cable, 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.
