Step 7: Locate the open connector at the end of your array of AC Modules and connect the end run cable to the 
Y-Cable until it is firmly seated. (Note: One End Run Assembly can support up to 16 continuous AC Modules in an 
array. Solar arrays larger than 16 AC Modules will require additional End Run assemblies.) 

 

 
Step 8: Secure the conduit to the NPT connector and install the appropriate wires into their respective terminal 
block locations (L1-N-L2-GND for the SM-EC-NA and L-N-GND for the SM-EC-EU) inside the End Run housing.
