1) Output circuits: These contacts must be incorporated into the control such that the
dangerous state is brought to an end if the output circuit is open. For categories 4 and 3,
they must be incorporated on dual-channels (x, y paths). Type 2 devices are suitable for
use up to PL c. Single-channel incorporation into the control (z path) is only possible with
a single-channel control and taking the risk analysis into account.
2) To indicate the status on both sides, the Com1 connections from the sender and receiver
must be connected to each other in the control cabinet (optional).
3) SELV/PELV safety extra-low voltage.
