4.1.5 Power Bay DC Charge Buses
Each standalone power bay has two vertical charge bars con-
necting all return terminals and all negative terminals of the recti-
fier shelves (Figure 3). These busbars are rated for the maximum
current supplied by the rectifier shelves.
In a multi-bay power system, the return vertical busbar connects
to an inter-bay return bar located across the top of the power and
distribution bays. Similarly the -48V vertical busbar connects to
an inter-bay -48V busbar, which terminates at the system shunt
located in the distribution bay.
Figure 4 shows a top view of the horizontal busbars between a
power bay and two distribution bays.
