5.14 NS Protection Connection
NS terminal: NS Protection is used for the German market currently. For plants sized more
than 30kVA, inverter NS Protection terminals could be used in daisy chain to external NS
Protection Relay to realize emergency stop when the NS Protection Relay changes its dry
contact status due to the grid abnormal running status. For detailed assembling procedure
for inverters in daisy chain mode refer to section
5.10.2 Assembling the COM Connector
NS Protection(including Passive Valid) can be set. When NS-1 and NS-2 are connected, the
inverters will emergently stop; otherwise, the inverters will operate normally. But if NS Pro-
tection is enabled on the iSolarCloud, refer to
, the inverters
will operate normally when NS-1 and NS-2 are connected, and the inverters will emergently
stop when NS-1 and NS-2 are disconnected.
The recommended wire conductor cross-section is 0.5 - 0.75 mm
2
，
and the maximum wir-
ing distance of NS protection loop must be less than 100 m.
Refer to section
5.9.1 Assembling the COM Connector
for detailed assembling procedure.
Plug the wires to
NS-1
and
NS-2
terminals according the labels on the bottom of the inverter.
When terminals
NS-1
and
NS-2
are turned on by the external NS protection relay, the inver-
ter will stop immediately.
