Note on the circuit diagram:
Use only relays with positively-driven contacts.
The protective elements switched in parallel with the contactors
are for arc suppression.
1) Output circuits. These contacts are to be incorporated into
the controller such that, when the output circuit is open, the
hazardous state is contolled.
In categories 3 and 4 to EN 954-1, they must be
incorporated on two channels (x, y paths).
