The Main Settings for the Analog inputs are:

– Set the CCT earth Nominal Primary Current value
– Set the Rated Network Frequency value, by default 50 Hz.
14.5 General Settings
The General Settings Tab enables you to configure the HW according to the Electronic Device

Do not make any changes to the eVM1 configuration unless you are familiar with the eVM1
and its Operating Tool. Changing the nominal currents and frequency values of the Main
Settings might result in malfunction of protection functions.
