Inordertoconnectthedeviceelectrically,thefollowingproceduresmustbefollowed:
1.DCconnection:First,connectthePVmodulestringstotheDCdisconnectswitch(notincluded
 inthescopeofdelivery).
2.ConnecttheDCdisconnectswitchtothesolarinverter(ensurecorrectpolarity).
3.ACconnection:Next,connecttheACconnectortothesolarinverterandthentothemains.
4.Beforeswitchingonthepower,checkallfeedersandconnectionsonelasttime.
5.CloseDCdisconnect.
6.ClosethecircuitbreakerontheACoutputside.
7.IncaseofsufcientPVvoltage(UPV>170V),thedevicenowgoesintothestart-upmode.
8.Inthecaseofanewinstallationthetimeanddatehavetobesetinsub-menuS(Setup)(see
