With single-phase service, all input lines are connected in parallel. Effectively, the
three groups of slots (each group comprising four individual slots) are connected
in parallel. However, with three-phase inputs, each line is connected to a
separate group of paralleled slots. Therefore, the physical location of a module in
the Mainframe will determine from which input line the module will draw power.
Balancing of phase currents can be achieved only if the power modules are
installed into the Mainframe so that there is an equal distribution of current
between the three groups of slots, and provided that the same total load is
applied to the set of modules in each group. Refer to Table 2-1 for the power
allocation from the input connector pins to the Mainframe slots.
In multi-Mainframe systems, each Mainframe has an independent AC/DC input.
The interconnect cable that daisy-chains the Mainframes together does not route
input power between assets. Therefore, the input power is not shared among the
assets comprising the system.
