Terminate the Unused End of the Cable
A ) Remove 60 mm of the cable sheath from the conductors.
B ) Check that all the terminator parts are present.
C ) Slide the hex nut onto the cable.
D ) Insert the cable end all the way into the cable organizer (up to the
stop).
E ) Attach the cap.
F ) Attach the terminated cable end to the PV racking with a cable clip or tie
wrap so that the Engage Cable and terminator do not touch the roof.

WARNING
: Never unscrew the hex nut. This action
can twist and damage the cable.
Connect to the AC Junction Box/Isolator
Connect the Engage Cable into the AC branch circuit junction box or
isolator. The Engage Cable uses the following wiring color code.
240 VAC Single-Phase Wires
208 VAC Three-Phase Wires
Black – L1
Red – L2
White – Neutral
Green – Ground
Black – L1
Red – L2
Blue – L3
White – Neutral
Green – Ground
The green wire acts as equipment ground (EGC).

After you have installed the microinverters, follow the procedures in the
Enphase Envoy Quick Install Guide
to activate system monitoring and
complete the PV installation.

Connecting the Envoy
•
Detecting the microinverters
•
Connecting to Enlighten
•
Registering the system
•
Building the virtual array
Connect the PV Modules
Mount the PV modules above the microinverters.
A ) Connect the DC leads of each PV mod-
ule to the DC input connectors of the
corresponding microinverter.
B ) Check the LED on the underside of the
microinverter. The LED flashes six times
when DC power is applied.
Energize the System
A ) If applicable, turn ON the AC disconnect or circuit breaker for the branch
circuit.
B ) Turn ON the main utility-grid AC circuit breaker. Your system will start
producing power
after a five-minute wait time.
C ) Check the LED on the underside of the microinverter:
LED
Indicates
Flashing green
Normal operation. AC grid function is normal and there
is communication with the Envoy.
Flashing orange The AC grid is normal but there is no
communication with the Envoy.
Flashing red
The AC grid is either not present or not within specifi-
cation.
Solid red
There is an active “DC Resistance Low, Power Off” or
“GFDI” fault. To reset, refer to the
Enphase M250 and
M215 Microinverter Installation and Operation Manual
