The wiring is supported by removable terminal blocks (X3, X4, X16...). Every terminal on every
terminal block is numbered. For example, when terminal X18.7 is indicated, reference is made to
the seventh terminal of terminal block X18. The numbers are also printed on the printed circuit of
the card.
