Wiring diagram variant 1: Signal contact for overvoltage protection
Depending on the setting in the Basic menu, the DC OVP Typ 2 option (overvoltage pro-
tection) either outputs a warning or an error on the display. Further information on the DC
OVP Typ 2 option 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.
IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to up-
date the inverter firmware.
Requirements for the S0 meter:
- 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
Recommended max. pulse rate of the S0 meter:
Description of the
'Fronius Solar
Net' LED
The 'Solar Net' LED is on:
the power supply for data communication within the Fronius Solar Net / interface protocol
is OK
The 'Solar Net' LED flashes briefly every 5 seconds:
data communication error in the Fronius Solar Net
- 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 electrical
power is available)
In this case, power for the DATCOM components must be supplied by connecting an
additional power supply to one of the DATCOM components.
To detect the presence of an undervoltage, check some of the other DATCOM com-
ponents for faults as required.
