micro inverter and then to the junction box. After laying out the grounding
conductor, secure the top of the grounding clips back onto the micro inverters.
WARNING
Correct AC grounding and short circuit protection must be provided to ensure
operational safety.
Step 6: Connect the Micro Inverters
6.1. Remove the temporary shipping cap from the t-branch on the AC trunk cable
and connect the micro inverter. Ensure the connection is secure and locked
into place by listening to “click” sounds when both lock pins are fully
inserted.
WARNING
Correct AC grounding and short circuit protection must be provided to ensure
operational safety.
6.2. Repeat for all micro inverters in the AC circuit.
6.3. For any unused connectors on the AC trunk cable, replace the temporary
shipping cap with a Sealing Cap. Listen for a click as the Sealing Cap is
connected to ensure that it is securely locked into place.
Note : Please check which type of the trunk cable you have before ordering micro
inverters.
Step 7: Terminate the Unused End of the AC Trunk Cable
7.1. Strip 10mm (about 0.5in) of the outer sheath from the end of the AC trunk
cable.
7.2. Each end cap has four parts: the sealing nut, clamp ring, seal and cap. Slide
the sealing nut, clamp ring and then the seal onto the AC trunk cable.
7.3. Insert the individual wires into the slots inside the cap of the end cap.
7.4. Screw the hex nut onto the cap. Use a wrench to ensure the hex nut is
screwed in all the way to the base of the cap.
WARNING Ensure the AC trunk cable and end cap do not touch the roof by using cable
clips or tie wraps to attach the trunk cable to the PV racking. Ensure that all
cabling is located underneath the PV module.
Step 8: Connect the AC Junction Box
Connect the AC trunk cable to the AC junction box using the appropriate gland or
strain relief fitting. The AC trunk cable requires a strain relief connector with an
opening of 1.6 cm (0.6 in) in diameter.
The wires in the AC trunk cable are identified by color: L1 is sheathed in Black, L2
is sheathed in Red, Neutral is sheathed in White and Ground is sheathed in
Green. Note the Neutral/White wire is unused.
WARNING
Although the AC trunk cable includes a grounding wire, the continuous grounding
conductor or grounding washers is still required.
Step 9: Connect the PV Modules
Mount the PV modules above the micro inverters, and then connect each micro
inverter to a PV module. (The micro inverter and PV module’s DC cables have two
connectors. Connect the micro inverter positive connector to the PV module
negative connector, and vice versa.)
CAUTION
Micro inverters and PV modules are installed using a one to two ratio.
