Note:
In case of events capturing, it is recommended to connect unused voltage
terminal to N voltage terminal.
4.2.2 Connection to the MV or HV Power System
In systems where voltage is measured at the secondary side of a voltage transformer
(say 11 kV / 110 V), the voltage transformer ratio should be entered first. Afterward
nominal voltage can be set to ensure correct measurement. In the next figure settings
for this particular example is shown. See 3.19.1 for details.
