ThesolarinverterhasaninsulationandgroundingmonitoringontheDCside.Theoptionscanbe
conguredintheSetupmenu“6.S->SolarISO/GND”(seepage23,section7.3.8).
Theinsulationmonitoringhastwomodes:
•ISO-ON-Error(thesolarinverterisdisconnectedfromthegridintheeventofaninsulation
 fault)
•ISO-ON-Warning(thesolarinverterindicatesthefaultbutisnotdisconnectedfromthegrid).
Deltassolarinvertersarefactory-settoISO-ON-Warningmodeondelivery.
Thegroundingmonitoringhastwomodes:
•PV+grounding(groundingmonitoringofthepositivepoleofthePVgenerator)
•PV-grounding(groundingmonitoringofthenegativepoleofthePVgenerator).
Inthesemodesthesolarinverterremainsinfeed-inoperationandwillnotbedisconnectedfromthe
gridincaseofafault.Theerrormessage“PV+groundingfault”or“PV-groundingfault”willappear
onthedisplay.
IfyouneedtoconnectthepositiveornegativepoleofthePVsystemtomeetrequirementsset
outbythemodulemanufacturer,youcandothis.Earthcontinuitymustbeimplementedcloseto
theinverter.WesuggestusingDeltasgroundingkit“GroundingSetASolar”(EOE99000115).The
groundingconnectionismonitoredandshouldbeconguredintheSetupmenu(seeabove).
Alternatively,itispossibletoturnofftheinsulation-andgroundingmonitoring:
•ISO/GNDOFF.
