In all cases, the equipment will compute the phase-to-ground voltage and the
neutral voltage.
The RA333 module has 3 high-speed analog inputs for measurement of TW
voltage, with a sampling frequency of 5 MHz. All channels are identified from 301
to 303.
Each analog input has two terminals: positive voltage, and negative, which are
used for one phase voltage, as shown in
inputs are galvanically isolated.

Connections shall use insulated flexible wires of 1.5 mm² cross section, 8 mm ring
terminals, and M3 holes.
