Stop!
If the voltage supply (DC 5 V via the backplane bus) fails, the
module will malfunction:
l Switched outputs carry voltage if one input is assigned with a
HIGH level,
l The module can be destroyed since the outputs are no longer
resistant to short circuits.
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.
