Connecting to the AC Grid
Use a standard AC cable with five wires (L1, L2, L3 + N + PE) or four wire (L1, L2, L3 +
PE). The cross section of the conductor of each wire must be 4 mm² to 16 mm².

3. Turn-off the DC switch of the DC Safety Unit.
4. Release the six Allen screws and carefully remove the cover of the inverter by pulling
out and lowering it down.
5. Release the four Allen screws and remove the cover of the DC Safety Unit.
CAUTION!
When removing covers, make sure not to damage internal components.
SolarEdge will not be held responsible for any components damaged as a
result of incautious cover removal.
