Due to the hardware platform a double command with single output via 2 relays
with one pair of contacts each can only be applied with restrictions. For this purpose
use the 2 power relays provided for motor control (only available in device versions
with power relays) (see Figure 5-11 and 5-12). Observe the internal grouping (see also
“General Diagrams” in Subsection A.2, Appendix A, Figures A-4, A-9, A-15, A-19,
A-23 and A-27).
