6.7 DC Connection
6.7.1 Checking before Connection
Check the following items before cable connections.

Check the open-circuit voltage of the PV array to ensure the open-circuit voltage is within the
max. DC voltage of the inverter.

Mark the negative and positive polarity of the cable.

Check the PV modules for possible ground fault.
WARNING:

Open-circuit voltage of the PV array should not exceed the max. DC voltage of
the inverter. The inverter may be damaged if otherwise.

If the ground fault is found, it must be removed before any DC connection.
WARNING:
Strictly follow all the instructions when connecting the cables.
WARNING:
Observe all the safety rules required by the PV array manufacture.
Start DC connection only when all checks and measurements meet requirements.
