Voltage
To activate the Fronius Datamanager anyway, switch the inverter on and off again on the
AC side and press any key on the inverter display within 90 seconds.

Output for internal voltage 12.8 V
or
input for external supply voltage
> 12.8–24 V DC (+ 20%)
Digital inputs: 0–3, 4–9
Voltage level: low = min. 0 V – max. 1.8 V; high = min. 3 V – max. 24 V DC (+ 20%)
Input currents: dependent on input voltage; input resistance = 46 kOhm
Digital outputs: 0–3
Switching capacity when supplied by the Fronius Datamanager 2.0 plug-in card:
3.2 W in total for all 4 digital outputs
Switching capacity when supplied by an external power supply with min. 12.8 –
max. 24 V DC (+ 20%), connected to Uint/Uext and GND: 1 A, 12.8–24 V DC (de-
pending on the external power supply) per digital output
The connection to the I/Os is made via the supplied mating connector.
Antenna plug
For screwing on the WLAN antenna
Modbus termination switch (for Modbus RTU)
Internal bus termination with 120-ohm resistance (yes/no)
Switch in position "on": Termination resistance of 120 ohm active
Switch in position "off": No termination resistance active
IMPORTANT! The termination resistance must be active for the first and last device
in an RS-485 bus.
For switching between master and slave mode within a Fronius Solar Net ring
IMPORTANT! All LEDs on the Fronius Datamanager 2.0 plug-in card are off in
slave mode.
