Nominal voltage
The nominal voltage corresponds to the "Agreed
input voltage Udin" according to EN 61000-4-30.
The nominal voltage defines the reference point
for:
·Overdeviation (EN 61000-4-30)
·Underdeviation (EN 61000-4-30)
·Transients
·Events
·Automatic scaling of graphics.
·When the nominal voltage U

Apply L2 - L4
These settings are configurable per phase.
Under the menu item "Apply L2 - L4" you can
apply the settings from phase L1 to phases L2,
L3 and L4 respectively, so that you do not have to
enter everything again.
·
No
- The settings from phase L1 are not adopted
for phases L1 to L4.
·
Yes
- The settings from phase L1 are adopted
for phases L1-L4.
