5.8.6 Connecting the NS Protection Signal Cable
Connecting NS Protection Signal Cables to Inverters
NO TE
● 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 switch is connected to GND (pin 13) at one end and to DIN5 (pin 15)
at the other end. The switch is turned o by default. When the switch is turned on, NS
protection is triggered. Rapid shutdown and NS protection use the same pins, which are
GND (pin 13) and DIN5 (pin 15). Therefore, you can use only one of the functions.
● The NS protection switch connection is the same for a single inverter and for cascaded
inverters.
● Log in to the FusionSolar app as an installer, choose Me > Device commissioning, and
connect to the WLAN hotspot of the inverter. Log in to the local commissioning system
as an installer, choose Settings > Feature parameters > Dry contact function, and set
Dry contact function to NS protection.
