Minimum wiring for commissioning [X3]
Danger to life due to bypassed safety functions
Safety functions must never be bypassed.
For the commissioning of the system without any safety systems, STOA and STOB can
be connected to the 24 V supply and GNDA and GNDB can be connected to GND in a
fixed manner.
Perform the minimum wiring of the inputs STOA/STOB and GNDA/GNDB for the
commissioning process in such a way that it must be removed when the final safety wiring
is performed.
