( Stop!
If the voltage supply (DC 24 V) 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 not
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.
