PRELIMINARY INSTRUCTIONS FOR INDICATION A TRIP OF THE
OVERVOLTAGE UNIT (SPD’S) ON THE FRONIUS TAURO

Note

In order to currently obtain information as to whether the integrated overvoltage contactors (SPDs for short) have
tripped, the display is done via a workaround. This can be done as follows.

Step 1

Connect via smartphone / tablet or laptop to the data communication board of your Fronius Tauro. You can find
out how to do this in your operating instructions.

Step 2

Go to the tab „Safety and Grid Regulations“

Step 3

Go to the tab „I/O Power Management“

Step 4

Activate the active power function at a free rule (in the example rule 1 - IO control position 8). Depending on the
setting of the value, in this case it was set to 0% output power of the inverter, the inverter regulates its output
power.

Note to step 4

Please note that the signal line of the SPDs is connected to position 8 ex works. If you change the connection,
you must take this into account here accordingly.
In the example we reduce the active power to an output power of 0%. This ensures that you also see this behavior
very clearly in the Solar.web at Archive. Since this is a very drastic measure, you are of course free to adjust this
value for yourself.
