Connecting NS Protection Signal Cables to the SmartLogger
● The NS protection function is applicable to grid code VDE-AR-N-4105, SWITZERLAND-
NA/EEA:2020-LV230, FINLAND-EN50549-LV230, or ANRE.
● The NS protection device is connected to the AI1 port and 12 V power output port on
the SmartLogger. The SmartLogger shuts down the inverter over the voltage change
detected at the AI1 port. When the NS protection device is disconnected, the AI1 port
voltage is 0 V, and the inverter shuts down. When the NS protection device is connected
again, the AI1 port voltage is 12 V, and you need to start the inverter manually.
