line and return per connection); the connector has six power pins plus ground.
Balance in phase currents can be achieved only if the power modules are located
in the Mainframe so that equal distribution between the three groups of slots is
maintained, and if the same load is applied to the set of modules in each group.
The load applied to a particular AC/DC input line is dependent on the location of
the modules in the Mainframe slots. The slots are grouped in sets of four: Slot 1-
4, Slot 5-8, and Slot 9-12. Slot 1 is the left-most slot, as viewed from the front.
Each of the four slots is supplied by one of the AC/DC input lines. In a double-
width and triple-width module, the module connector is located so that it mates to
a backplane connector in the right-most slot, as viewed from the front of the
Mainframe. Refer to Table 6-1 for Mainframe input connector pinout and power
allocation to the Mainframe slots.
