Notes
Clamping points 17 to 20 and 37 to 40 of the I/O module are also labeled 17 to 20 and 37 to
40 on the analog terminal module.
Clamping points L+; M; +; -; of the analog terminal module are auxiliary terminals and are not
connected to the I/O module.
There is an electrical connection between all clamping points with the same designation
(labeling) on the analog terminal module (multiplication terminal).
