Step 10: Connect the Engage Cable to AC Junction Box(es)
a. Connect Engage Cable into the AC branch
circuit junction box using an appropriate gland
or strain relief fitting. The Engage Cable
requires a strain relief connector with an
opening of 1.3 cm (0.5 inches) in diameter.
b. Connect the Engage Cable into additional AC
junction boxes as needed to transition to
conduit between smaller sub-arrays.
Refer to the wiring diagrams on page 41 for more
information.
Wire colors are listed in the following table.
240 Volt AC Split Phase Wiring
Black - L1
Red - L2
White - Neutral
Green - Ground
NOTE: The green wire acts as equipment ground (EGC).
NOTE: Because the DC circuit is isolated and insulated from ground, the M215-60-2LL-
S22-IG, S23-IG, and S24-IG do not require a GEC. Ground fault protection (GFP) is
integrated into the microinverter.
Balanced 208 VAC (three-phase) is accomplished by alternating phases between
microinverters as shown:
