Fronius Solar Net' Led Description - Fronius Symo Serie Instructions De Service

Switching Variant 1: Signal Contact for Surge Protection
The DC SPD (surge protection) option issues a warning or error on the display, depending
on the setting in the basic menu (signal input submenu). More detailed information on the
DC SPD option can be found in the Installation Instructions.
Switching Variant 2: S0 Counter
A counter for recording self-consumption per S0 can be connected directly to the inverter.
This S0 counter can be placed at the feed-in point or in the consumption branch. A dynamic
power reduction can be set under the DSO Editor menu subitem in the settings on the Fro-
nius Datamanager website (see Fronius Datamanager 2.0 Operating Instructions on the
homepage at www.fronius.com)
IMPORTANT! Connecting an S0 meter to the inverter may require an inverter firmware up-
date.

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. due to a short circuit in Fronius Solar Net ring)
Undervoltage (no short circuit, voltage in Fronius Solar Net < 6.5 V, e.g. if too many
DATCOM components are in Fronius Solar Net and the electrical supply is insufficient)
In this case, an additional power supply is required for the Fronius DATCOM compo-
nents using an external power supply (43,0001,1194) on one of the Fronius DATCOM
components.
