Description Of The "Fronius Solar Net" Led - Fronius Primo 3.0-1 Instructions De Service

Wiring diagram variant 2: S0 meter
A meter for recording the self-consumption of each S0 can be connected directly to the
inverter. This S0 meter can be positioned directly at the feed-in point or in the consump-
tion branch. As one of the settings on the Fronius Datamanager website, a dynamic
power reduction can be set under the "DNO Editor" menu item (see Fronius Dataman-
ager 2.0 Operating Instructions on our website www.fronius.com)
IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to
update the inverter firmware.

Must comply with the IEC62053-31 Class B standard
Max. voltage 15 V DC
Max. current when ON 15 mA
Min. current when ON 2 mA
Max. current when OFF 0.15 mA
Overcurrent (current flow > 3 A, e.g. resulting from a short circuit in the Fronius
Solar Net ring)
Undervoltage (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if there
are too many DATCOM components on the Fronius Solar Net and not enough elec-
trical power is available)
In this case, power for the Fronius DATCOM components must be supplied by con-
necting an additional power supply (43,0001,1194) to one of the Fronius DATCOM
components.
To detect the presence of an undervoltage, check some of the other Fronius DAT-
COM components for faults as required.
