Input Under-/Overvoltage Cut-out
Input fuse
The modules do not incorporate any fuse. External fuses in-
stalled in the wiring to the input are essential.
If the input voltage remains below 0.6 Ui min or exceeds
1.1 Ui max (approx. values), an internally generated inhibit
signal disables the output(s). When checking this function
the absolute maximum input voltage rating Ui abs must be
carefully considered (see table above).
