When connecting in series, consider the requirements of manipulation protection and the
protection against bypassing or from overriding the safety switch (EN ISO 14119).
}
When the safety inputs of the safety switch are controlled by an upstream device, and
they are not wired with 24 V,
– They must be monitored for shorts across the contacts in dependence of the Perform-
ance Level or SIL level to be achieved
or
– The the faults at the safety inputs that can occur by shorts across contact will have to
be excluded by suitable measures (e.g. wiring in accordance with EN 602041).

The use of Safety Device Diagnostics is described in the System Description "Safety
Device Diagnostics".
CAUTION!
Do not connect the signal output to 0 V!
If the signal output Y32 is connected to 0 V, the safety switch may be dam-
aged as a result. Connect the signal output Y32 to a consumer, e.g. to the
input on a control system, or leave the signal output unconnected. Also note
