Step 8 - Connect The Engage Cable To Ac Junction Box(Es) - enphase M215 Installation And Operation Manual

Step 8 – 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 located on
page 29 for more information.
NOTE: The Engage Cable uses a
different wiring scheme than used with
other Enphase Microinverters. Be aware
of the difference in wire color code.
240 Volt AC Split Phase Wiring
Black – L1
Red – L2
White – Neutral
Green - Ground
NOTE: The green wire acts as equipment ground. A continuous GEC for system ground is
also required as described in the next step.
Wires are identified as follows: L1 is sheathed in Black, L2 is sheathed in red, L3 is sheathed in
blue, Neutral is sheathed in white, and Ground is sheathed in green. The grounding wire is used
to ground the microinverters. A WEEB or continuous ground is required in addition to this green
grounding wire.
Balanced 208 VAC (3-phase) is accomplished by alternating phases between microinverters as
shown:
