Explanation of Various wiring variants can be connected to the multifunction current interface. However,
the multifunction these cannot be operated simultaneously. For example, if an S0 meter is connected to the
current interface multifunction current interface, it is not possible to connect a signal contact for overvoltage
protection (or vice versa).
Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load imped-
ance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or GND

Designation
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.
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.
The 'Solar Net' LED
indicates whether the Fronius Solar Net power supply is available
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.
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.
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.
