WARNING: The device may only be operated in one of the connection
options shown above! When measuring current, an external shunt
must be connected to measurement input U!
DANGER: Current measurement on the high side (between plus and
load) only for voltages lower than 50 V! In this case the entire device
is on high potential. Particularly to be considered when connecting
switches to J1-6.
