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 28 for more information.
Wires are identified as follows. For 400 Vac, L1 is sheathed in brown, L2 is sheathed in black, L3 is
sheathed in grey, Neutral is sheathed in blue, and protective earth is sheathed in green/yellow. The
earthing wire is used to earth the microinverters. For single-phase, L2 and L3 are not present.
Balanced 400 Vac (3-phase) is accomplished by alternating phases between microinverters as
