4.3.2  DC Cable Connection Procedures 

 

Make sure that all the DC and AC cables to the inverter are not live before 
you start the electrical work. 

 

 

Neither the DC positive pole nor the DC negative pole of the PV string is 
permitted to be grounded. 

 

Step 1

 

Assemble the DC plug-in connectors and disconnect the DC switch. 

 

Step 2

 

Check the connection cable of PV string for the correct polarity and that the 
open-circuit voltage does not exceed the inverter input limit 1000V, even 
under the lowest operating temperature.
