Architecture
The plant architecture is shown in the diagram below. The CPS6000-M2 System rectifiers accept
alternating current (ac) power and produce a regulated dc -48V nominal voltage distributed to
float the batteries, power the controller and power the loads through distribution circuit breakers
or fuses. Batteries are used to provide backup dc power when the ac is lost. They are connected in
parallel with the rectifiers through either optional battery breakers or a low voltage disconnect
(LVD). AC power is distributed to each rectifier through ac terminal blocks located in the ac
termination panel at the top of the frame. The Millennium II system controller monitors and
controls system operation.
