 Stop!
If the voltage supply (DC 5 V via the backplane bus)fails, the
module will malfunction:
z Switched outputs carry voltage if one input is assigned with a
HIGH level,
z Themodulecanbedestroyedsincetheoutputsarenot
resistant to short circuits anymore.
The emergency-off switch ensures that when being operated, the
outputs do not carry any voltage and the inputs are not assigned
with a HIGH level.
