6. Fit the appropriate AC-trunk end cap on the unused ends of 
the AC-trunk cable. 

 

Connect the AC-TRUNK cable/s coming from the MICRO inverters 
to the junction box or to the AC distribution panel. 

 

8. Use the duplicate label in the attached plastic bag to create a map of the system by placing the adhesive 
labels on the diagram (found in the appendix, part 7).
