4. Electrical Connections
The device may only be operated in one of the connection options shown below.
Warning:
Voltage measurement on the high
side (between plus and load) is
recommended only for voltages up
to 50V!
In this case the entire device is on
high potential. Particularly to be
considered when connecting
switches to JP1-6.
