Chapter 2: Installing the Hardware Infrastructure 2-25
Cable length restrictions may prevent installing all power supplies in
the same location. In this case, it may be necessary to install a
separately switched AC main circuit so that the power supplies can
still be controlled at the same time. If local electrical codes or special
circumstances require the installation of more than one switched AC
main circuit for the power supplies, all the main circuit switches
should be in the same easily accessible location.
Do not install the CBS power supply in the ceiling.
1. Have an electrician install new AC receptacles if needed.
2. Do not plug the CBS power supply into an AC receptacle until
steps 1 – 6 in the next section are complete and the transmit
antenna is connected to the CBS.
Connecting CBS Power Supplies to CBSs
Each CBS power supply can power up to five CBSs as shown
previously in the store configuration illustration. The wiring is the
same for each group of up to five CBSs.
Follow these steps to connect a CBS power supply to each group of up
to three CBSs:
1. Cut a length of power cable that is long enough to reach from the
power supply to a CBS.
2. Splice the power cable wires to the pigtail supplied with the power
supply (black to black and red to white) and then crimp the
provided crimp connectors over the splices.
