All contacts for the mains and logic supply are cross wired at the connection [X9A]. The intermediate
circuits are not cross wired (DC+/DC-). The first device is connected with the two voltage sources.
1-phase devices with the same power class and 1-phase devices with different power classes can be
connected.
