After completing wiring, fix the cable on the beam (not included in the scope of supply) to
avoid excessive stress on the cable.
Seal the bottom cable entries with fireproof mud (foaming materials), remove debris in the
HV cabinet, close and lock the cabinet door.
Remove the key to the HV cabinet door, and store it in the operation box.

DC Connection
6.6.1 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 less
than the max. DC voltage of the inverter.
•
Mark the negative and positive polarity of the cable.
•
Check the PV modules for possible ground fault.
•
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 a ground fault is detected, remove it before performing any DC connection.
Strictly follow all the instructions when connecting the cables.
Observe all the safety rules specified by the PV array manufacture.
Start DC connection only when all checks and measurements meet requirements.
