Description Of The "Fronius Solar Net" Led - Fronius Primo 3.0-1 Instructions De Service

Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load imped-
ance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or GND
Wiring diagram variant 1: Signal contact for surge protection device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD option
(surge protection device) either outputs a warning or an error on the display. Further infor-
mation on the DC SPD option can be found in the Installation Instructions.
Wiring diagram variant 2: S0 meter
A meter for recording the self-consumption of each S0 can be connected directly to the in-
verter. This S0 meter can be positioned directly at the feed-in point or in the consumption
branch. As one of the settings on the Fronius Datamanager website, a dynamic power re-
duction can be set under the "EVU Editor" menu item (see Fronius Datamanager 2.0 Op-
erating Instructions on our website www.fronius.com)
IMPORTANT! In order to connect an S0 meter to the inverter, it may be necessary to up-
date the inverter firmware.
