Abstract

Icon indicia are provided on input, output and plug-in power processing units to permit proper matching of plug-in units with each other and with the input and output power processing units in a power distribution system. The indicia are in a co-ordinated matrix format with input icons on a designated chroma background to identify input voltages and output icons on a second designated chroma background to identify output voltages. Icons and background chroma on the plug-in power processing units are coordinated with related icons and background chroma at the same matrix position on other plug-in units and/or the input and output units to assure the compatibility of all the units. A craftsman inserting a plug-in unit onto a shelf of the power chassis need merely compare the unit's icon and chroma background indicia with the input, output, or other unit's icons and associated chroma background indicia to be assured of inserting the correct plug-in unit into the particular shelf.

A power plant, comprising:

a supporting infrastructure including a shelf for accepting a plurality of modular power processing circuits;
an input distribution unit;
an output distribution unit;
a plurality of intermediate power processing units arranged in a linear series and electrically connected intermediate the input distribution unit and the output distribution unit in order to process power supplied from the input distribution unit and deliver power to the output distribution unit;
the input distribution unit including means for accepting power from a power source and further including a first identification indicia providing an indication of an output voltage supplied to the plurality of intermediate power processing units by a label having a first radiant energy frequency visually displaying a first color in a first specific matrix position;
the output distribution unit including means for distributing power to a load and further including a second identification indicia providing an indication of an appropriate input voltage to be supplied to it by the plurality of intermediate power processing units by a label having a second radiant energy frequency visually displaying a second color in a second specific matrix position;
identification indicia associated with each of the intermediate power processing units, including;
a third identification indicia providing an indication of an acceptable input voltage accepted from the input distribution unit by including the first radiant energy frequency visually displaying the first color in the first specific matrix position, wherein a match between the voltage from the input distribution unit and the acceptable input voltage is indicated by an identity of the radiant energy frequency displayed;
and
the third identification indicia providing an indication of an output voltage of the intermediate power processing unit supplied to the output distribution unit by including the second radiant energy frequency visually displaying the second color in the second specific matrix position, wherein a match between the output voltage of the intermediate distribution unit and a voltage acceptable to the output distribution unit is indicated by an identity of the radiant energy frequency.
