Note: In case of events capturing, it is recommended to connect unused voltage terminal to N voltage
terminal.

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 3.21.1 for
details.
