Fronius Dataman-
ager during the
night or when the
available DC volt-
age is insufficient
The Night Mode parameter under "Display Settings" in the Setup menu is preset to OFF in
the factory.
For this reason the Fronius Datamanager cannot be accessed during the night or when the
available DC voltage is insufficient.
To nevertheless activate the Fronius Datamanager, switch the inverter off and on again at
the mains and press any key on the inverter display within 90 seconds.
See also the chapters on "The Setup menu items", "Display settings" (Night Mode).

Internal voltage output 12.8 V
or
input for an 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 power is supplied by the Fronius Datamanager 2.0 plug-
in card: 3.2 W in total for all 4 digital outputs
Switching capacity when power is supplied by an external power supply delivering
min. 12.8 - max. 24 V DC (+ 20%), connected to Uint / Uext and GND: 1 A, 12.8 -
24 V DC (depending on external power supply) for each digital output
The connection to the I/Os is established via the mating connector supplied.
(8) Antenna socket
This is where the WLAN antenna is connected
(9) Modbus termination switch (for Modbus RTU)
Internal bus terminator with 120 ohm resistor (yes/no)
Switch in "on" position: 120 ohm terminating resistor active
Switch in "off" position: no terminating resistor active
IMPORTANT! On an RS485 bus, the terminating resistor on the first and last device
must be active.
(10) Fronius Solar Net Master / Slave switch
To switch from master to slave mode within a Fronius Solar Net ring
IMPORTANT! In slave mode, all the LEDs on the Fronius Datamanager 2.0 plug-in
card are off.
