1. A method for connecting a load to a DC network by way of a switching module, the switching module including a first module connection, a second module connection, and a third module connection;
a first electronic switch being connected between the first module connection and the second module connection; and
a second electronic switch being connected between the second module connection and the third module connection, the method comprising:
connecting the first electronic switch and the second electronic switch in the anti-series between the first module connection and the third module connection;
connecting a network line of the DC network, upon bidirectional overcurrent protection against overcurrents in both current directions being required between the load and the DC network, to the first module connection of the switching module and a load line of the load, to the third module connection of the switching module, the second module connection remaining disconnected; and
connecting the network line of the DC network, upon unidirectional overcurrent protection against overcurrents in one current direction being required between the load and the DC network, to the first module connection, and connecting the load line of the load to the second module connection of the switching module, the third module connection remaining disconnected or being connected to the network line of the DC network.
