l For single phase 10-11.4kW inverters-ConnecttheDCwiresfromthePVinstallationto
theDC+andDC-terminalblocks,accordingtothelabelsontheterminals:

o
Useastandardflat-bladescrewdrivertoconnectthewirestothespring-clamp

l For three phase inverters–Dooneofthefollowing:

o
Safetyswitchversionwithout terminal blocks on the DC side-ConnecttheDC
wiresfromthePVinstallationtotheDC+andDC-terminalsoftheswitch,
accordingtothelabelsintheSafetySwitch.

o
Safetyswitchversionwith terminal blocks on the DC side-ConnecttheDC
wiresfromthePVinstallationtotheDC+andDC-terminalblocks(seealso
Figure 29).
5. IftheSafetySwitchhasapre-assembledRGM,fliptheRGMplateupwardstoitsoriginal
position.
6. ClosetheSafetySwitchcover:Attachtheswitchcoverandsecureitbytighteningthefour
