You can make an electrical association by doing one of the following:
-
Drag an item from the Electrical Index to an appropriate place in the electrical tree of the Electrical Engineer.
-
In a cable block diagram, connect two items using a cable or a connector. See Working with Smart Data and Auxiliary Graphics in a CBD.
Note that electrical associations are governed by a strict set of rules. You can associate electrical items according to the rules that are specified in the following table:

Special Conditions
The software creates the following electrical items automatically in the Electrical Engineer when you create them in the Electrical Index. These items appear at the root of the Electrical Engineer tree view after you create them in the Electrical Index even if they do not have an existing electrical relation.
-

-
Generators
-
Battery banks
-
UPSs
-
Battery chargers
