4. Ensure that there is no ground fault in the PV array (see service manual at www.SMA-
Solar.com).
5. Check whether the DC connectors have the correct polarity.
If the DC connector is equipped with a DC cable of the wrong polarity, the DC connector must
be assembled again. The DC cable must always have the same polarity as the DC connector.
6. Ensure that the open-circuit voltage of the PV array does not exceed the maximum input
voltage.
7. Connect the assembled DC connectors to the inverter.
☑ The DC connectors snap into place.
