Item Designation
Wiring diagram variant 2: 4-20 mA
Pin 1: +
Pin 2: -
Use the 2-pin mating connector supplied with the inverter to connect to the multi-
function current interface.
(2) Fronius Solar Net connection / interface protocol IN
(3) Fronius Solar Net connection / interface protocol OUT
'Fronius Solar Net' / interface protocol input and output for connecting to other
DATCOM components (e.g. inverter, sensor box, etc.)
If several DATCOM components are linked together, a terminating plug must be
connected to every free IN or OUT connection on a DATCOM component.
For inverters with a Fronius Datamanager plug-in card, two terminating plugs are
supplied with the inverter.
(4) The 'Solar Net' LED
indicates whether the Fronius Solar Net power supply is available
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 Fro-
nius 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 components for faults as required.
After cutting out because of overcurrent or undervoltage, the inverter attempts to
restore the power supply in the Fronius Solar Net every 5 seconds while the fault
is still present.
Once the fault is rectified, power to the Fronius Solar Net will be restored within 5
seconds.
(5) The 'Data transfer' LED
flashes while the USB stick is being accessed. The USB stick must not be remo-
ved while recording is in progress.
(6) USB A socket
for connecting a USB stick with maximum dimensions of
65 x 30 mm
The USB stick can function as a datalogger for an inverter. The USB stick is not
included in the scope of supply of the inverter.
