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
Item Designation
(1) Switchable multifunction current interface. For more details, refer to the section
below entitled "Explanation of the multifunction current interface"
Use the 2-pin mating connector supplied with the inverter to connect to the multi-
function current interface.
(2)
(3)
Fronius Solar Net connection / interface protocol IN
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
(5) The 'Data transfer' LED
flashes while the USB flash drive is being accessed. The USB flash drive must
not be removed while recording is in progress.
(6) USB A socket
for connecting a USB flash drive with maximum dimensions of
65 x 30 mm (2.6 x 2.1 in.)
The USB flash drive can function as a datalogger for an inverter. The USB flash
drive is not included in the scope of supply of the inverter.
(7) Floating switch contact with mating connector
max. 250 V AC / 4 A AC
max. 30 V DC / 1 A DC
max. 1.5 mm² (AWG 16) cable cross-section
Pin 1 = NO contact (Normally Open)
Pin 2 = C (Common)
Pin 3 = NC contact (Normally Closed)
Use the mating connector supplied with the inverter to connect to the floating
switch contact.
(8) Fronius Datamanager with WLAN antenna
or
cover for option card compartment
(9) Cover for option card compartment
