Pin 1 = measurement input: max. 20 mA, 100-ohm measurement resistor (appar-
ent ohmic resistance)
Pin 2 = max. short circuit current 15 mA, max. open circuit voltage 16 V DC or
GND
Switching Variant 1: Signal Contact for Surge Protection
The DC SPD (surge protection) option issues a warning or error on the display,
depending on the setting in the basic menu (signal input submenu). More de-
tailed information on the DC SPD option can be found in the Installation In-
structions.
Switching Variant 2: S0 Counter
A counter for recording self-consumption per S0 can be connected directly to
the inverter. This S0 counter can be placed at the feed-in point or in the con-
sumption branch. A dynamic power reduction can be set under the DSO Editor
menu subitem in the settings on the Fronius Datamanager website (see Fronius
Datamanager 2.0 Operating Instructions on the homepage at www.fronius.com)
IMPORTANT! Connecting an S0 meter to the inverter may require an inverter
firmware update.
Requirements for the S0 meter:
-
Must meet standard IEC 62053-31 Class B
-
Max. voltage: 15 V DC
-
Max. current when ON: 15 mA
-
Min. current when ON: 2 mA
-
Max. current when OFF: 0.15 mA
