By clicking at the Text box in the Electrical connection column, an electrical connection (elconn) can be selected. The dropdown list will show all existing elconn elements for the selected equipment item. In case the equipment item does not have any or too few elconns, it is possible to add new ones by selecting the Add… command.

This will bring up the Create electrical connection dialogue, where the new electrical connection can be created and its attributes set. The Catalogue reference is of special importance as it will be used to determine how many terminals the elconn has.
