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.
When measuring current, an external shunt must be connected to U1!
