Do not connect any voltages externally to digital outputs!
Reason: Externally voltages at an output or several outputs may cause that
other outputs are supplied through that voltage instead of voltage UP3 (reverse
voltage). This ist not intended usage.
CAUTION!
Risk of malfunction by unintended usage!
If the function cut-off of the digital outputs is to be used by deactivation of the
supply voltage UP3, be sure that no external voltage is conncted at the outputs
DO0..DO7.
