Setting NS Protection Remote Shutdown
● The NS protection function applies to areas in compliance with the VDE 4105 standard,
and the grid code needs to be set to VDE-AR-N-4105 or SWITZERLAND-NA/EEA:2020-
LV230.
● 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.
