a signal contact for the surge protection device (or vice versa).
Pin 1 = measurement input: max. 20 mA, 100 Ohm measurement resistor (load
impedance)
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 protective device
Depending on the setting in the Basic menu (Signal Input submenu), the DC SPD
option (surge protective device) either outputs a warning or an error on the dis-
play. Further information 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 dir-
ectly to the inverter. This S0 meter can be positioned directly at the feed-in point
or in the consumption branch.
IMPORTANT! In order to connect an S0 meter to the inverter, it may be neces-
sary to update the inverter firmware.
The S0 meter must comply with the IEC62053-31 Class B standard
Recommended max. pulse rate of the S0 meter:
