6.7.8.2 Setting NS Protection Remote Shutdown
Context
●
The NS protection function is available only in Germany. Choose Monitoring
> Running Param. > Grid Parameters and set Grid code to VDE-AR-N-4105.
●
The NS protection device is connected to the AI1 port and 12V power output
port. 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.
