<1> Differential input!
In case of a ground-based input signal, the terminal X131.8 must be connected to the reference potential M.
Caution:
The voltage between an input (X131.7 or X131.8) and the grounding point must not exceed 35 V.
When the load resistor is switched in (S5.0 closed), the voltage between the input terminals must not exceed 15 V.
<2> For p0756 = 2, 3, 5 the units are mA.
For p0756 = 0, 4 the units are V.
