Wiring diagram variant 1: Signal contact for overvoltage protection
Depending on the setting in the Basic menu, the DC OVP option (overvoltage protection)
either outputs a warning or an error on the display. Further information on the DC OVP op-
tion can be found in the installation instructions.
Wiring diagram variant 2: S0 meter
A meter for recording the self-consumption of each S0 can be connected directly to the in-
verter. This S0 meter can be positioned directly at the feed-in point or in the consumption
branch. As one of the settings on the Fronius Datamanager website, a dynamic power re-
duction can be set under the "EVU Editor" menu subitem (see Fronius Datamanager op-
erating instructions under
www.fronius.com/QR-link/4204260173EA)
