Connect by strictly following the circuit diagram; 

 

Measure and make sure the string open-circuit voltage meets the 
requirements of the combiner box before inserting the fuse; 

 

Identify the positive pole and negative pole before connection. 

 

 

Only qualified personnel or professional electrician can perform the 
operation and wiring described in this manual. 

 

All operations and wirings must in full accordance with the national and
