Solar Net" Led Description - Fronius Symo 10.0-3 208-240 Instructions De Service

Switching Variant 1: Signal Contact for Overvoltage Protection
The DC OVP type 2 (overvoltage protection) option issues a warning or error on the dis-
play, depending on the setting in the basic menu. More detailed information on the DC OVP
type 2 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.
IMPORTANT! Connecting an S0 counter to the inverter may require an inverter firmware
update.
Requirements for the S0 counter:

Must meet standard IEC 62053-32 Class B
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 (not a short circuit, voltage in Fronius Solar Net < 6.5 V, e.g., when too
many DATCOM components are connected to Fronius Solar Net and electrical supply
is insufficient)
In this case an additional energy supply to one of the DATCOM components via an
external power supply is required.
Check other DATCOM components for errors in order to identify an existing undervolt-
age.
