Applies to the voltage range between V[0]

and 0 V.
41)
In the case of a fault (0 V cable open circuit) maximally the leakage current flows in the OSSD cable. The
downstream controller must detect this status as LOW. A FPLC (fail-safe programmable logic controller) must
be able to identify this status.
42)
The maximum rated load inductance is higher with lower switching sequence.
43)
Make sure to limit the individual line core resistance to the downstream controller to this value to ensure that
a cross-circuit between the outputs is safely detected. (Also note EN 60204<1.)
44)
When active, the outputs are tested cyclically (brief LOW). When selecting the downstream controllers, make
sure that the test signals do not result in deactivation.
