Explanation of Different switching variants can be connected to the multifunctional power interface. These
Multifunctional variants cannot be operated at the same time, however. For example, if an S0 counter is
Power Interface connected to the multifunctional power interface, a signal contact for overvoltage protec-
tion cannot be connected, and vice versa.
Pin 1 = measurement input: max. 20 mA, 100 ohm measurement resistor (apparent ohmic
resistance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or GND

Description
Switchable multifunctional power interface. For a more detailed explanation, see
the section entitled "Explanation of Multifunctional Power Interface" which follows
Use the 2-pin mating connector supplied with the inverter to connect to the multi-
functional power interface.
Fronius Solar Net/interface protocol IN connection
Fronius Solar Net/interface protocol OUT connection
Fronius Solar Net/interface protocol input and output for connecting to other DAT-
COM components (e.g., inverter, Fronius Sensor Box, etc.)
When networking several DATCOM components, a termination plug must be
placed on each free IN and/or OUT connection of a DATCOM component.

flashes when accessing the USB flash drive. The USB flash drive must not be re-
moved during this time.
USB A socket
for connecting a USB flash drive with a maximum size of
65 x 30 mm (2.6 x 2.1 in.)
The USB flash drive can act as a data logger for an inverter. The USB flash drive
is not part of the scope of supply for 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 = root (Common)
Pin 3 = NC contact (Normally Closed)
Use the mating connector supplied with the inverter to connect to the floating
switch contact.
