DC DISCONNECT LABEL CALCULATION

1. Operating current:

               A. Imp X number of source circuits.

2. Operating voltage:

               A. Vmp X number of modules in series per source circuit.

3. Max system voltage:

               A.Voc X Max number of modules in series per 

                source circuit X Correction Factor of Ambient temp.

4. Short circuit current:

               A. Isc X 1.25 X number of source circuits
