* The voltage may only be used to supply the external terminating resistor. The voltage must not be
looped through to the next connector with a cable.
** We recommend that you connect the functional earth via the M12 thread (because it has a larger
surface area than terminal 5).
Note
The cable shield support is described in the Hardware Installation Instructions for the M12
cable connector.
