step 4 Check for polarity correctness.

If the PV polarity is reversed, the inverter will be in a fault or alarm state and will

not operate normally.

- - End

5.6.3 Installing the PV Connectors

step 1 Rotate the DC switch to "OFF" position.

step 2 Check the cable connection of the PV string for polarity correctness and ensure that the

open circuit voltage in any case does not exceed the inverter input limit of 600 V.
