Total Access Rackmount 6-Amp Power Supply Battery Charger Installation and Maintenance Practice
DC Power Output
The 4-foot long, three conductor PS/BC power output wire originates at the
modular connector and terminates at three #6 ring lugs for customer designated connection.
Wire color-code is as follows:
• Red = –54 VDC
• Black = Return
• Green = Ground
PS/BC to Battery Configurations
The basic design configuration consists of one PS/BC with two batteries. A variety of other
configurations are possible with more (or less) redundant capability, see
configurations I and II.
PS/BC
A
These would include one or two PS/BCs, none, one, or two batteries, or some combination of
PS/BC and battery. The most reliable configuration would be two PS/BCs with two batteries
each and with independent AC sources. The two PS/BC outputs would terminate at a single
load that has primary and secondary power sharing terminals.
