<1> Differential input!
In case of a ground-based input signal, the terminal X521.2 must be connected to the reference potential M.
Caution:
The voltage between an input (X521.1 or X521.2) and the ground 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 p4056 = 2, 3, 5 the units are mA.
For p4056 = 0, 4 the units are V.
