E NS Protection
Connecting the Inverter to the NS Protection Signal Cable
NO TE
● The NS protection function applies to areas in compliance with the VDE4105 standard,
and the grid code needs to be set to VDE-AR-N-4105.
● 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 SUN2000. Log in to the local commissioning
system as an installer user, choose Settings > Feature parameters > Dry contact
function, and set Dry contact function to NS protection.
