Connecting Power Supply Cables
Refer to the illustrations in the “CBS Power Supply Cable Connections”
section. Power supply cable routing is store dependent. The power
connector provides flexibility to connect additional CBSs in series from
one CBS to another or in parallel from a CBS to three other CBSs.
Connecting CBS Power Supplies to AC Power
Place the CBS power supplies with the host computer system, if
possible. Plug all power supplies into a common power strip so that
you can power them on and off at the same time for reset purposes.
In some cases, cable length restrictions may prevent you from
installing all power supplies in the same location. In this case, you
need to install a separately switched AC main circuit so that you can
still control the power supplies at the same time. If local electrical
codes or special circumstances require you to install 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 five CBSs:
1. Cut a length of power cable that is long enough to reach from the
power supply to a CBS.
