connection of pins Explanation
Upper row
Bridge between
pin 2 and 4
Lower row
Bridge between
pin 4,2
(socket upper row) and
Pin 2
(socket lower row)
Advantage:
Two inputs on lower
socket
(here I0.00 and I0.01),
Thereby
- fewer cables,
- connection to
changeover switch
or
converter possible.
Please note:
If the lower socket is
used for two input cables,
the upper plug must
remain unused
(see example 2).
