WARNING!
Except for this special case of a short time signal (for an external trip), it is not permitted
to feed any long-term or continuous voltage into the Digital Inputs.
In other words, it is strongly discouraged to try to supply the WIC1 (for a considerable
time) via the Digital Inputs.
If this is ignored the Digital Input can be overloaded, and this can lead to a permanent
damage of the WIC1.
