Surge Protective Device; Surge Protective Device (Spd) - Fronius Tauro 50-3 Operating Instructions Manual

Surge protective The inverter is equipped with an integrated surge protective device on the DC
device and AC side in accordance with IEC 62109-2. The surge protective device pro-

Surge protective
device (SPD)
IMPORTANT!
After setting the function described above, the inverter will also respond if the 2-
pole signal cable of the surge protective device is interrupted or damaged.
The surge protective device (SPD) protects against temporary over-
voltages and dissipates surge currents (e.g. lightning strike). Building on
an overall lightning protection concept, the SPD helps to protect your
PV system components.
If the surge protective device is triggered, the colour of the indicator
changes from green to red (mechanical display).
There is the option of a digital indication when an SPD has tripped. For
setting this function, see PDF "Temporary SPD Triggering" in the Service
& Support area at www.fronius.com
