Install the Enphase Three-Phase
Field Wireable Connectors
Use Enphase Three-Phase Field Wireable QD Connectors with an Enphase QD Cable or a 10AWG or a 12AWG eld extension cable to:
• Easily connect QD Cables on the roof without complex wiring
• Use a mated pair of connectors to end-feed the branch circuit with an AC connection
• Use a Male connector along with a QD-LINKFW-10 center tap adapter cable to center-feed the branch circuit with an AC connection
• Use mated pairs of connectors to connect with a remote part of the array
PREPARATION
For full installation instructions for the Enphase IQ8D Microinverters, read and follow
all warnings and instructions in this guide and in the Enphase IQ8D Commercial PV
Design Guide and IQ8D Microinverter System manual at: enphase.com/support.
Check that you have Enphase Three-Phase Field Wireable QD Connectors as needed
for your installation. Both female and male connectors are sold in packs of ten:
• Three-Phase Field Wireable QD Connector (female): (QD-CONN-10F)
• Three-Phase Field Wireable QD Connector (male): (QD-CONN-10M)
Make sure you have the following recommended tools:
• Screwdriver blade width 4mm to 3.2mm (1/8”) (recommended tool to torque
the screw on contact carrier and to disconnect eld wireable connector).
• 30mm wrench

Follow the steps to assemble Enphase Field Wireable QD Connectors for three-phase.
FEMALE
A) Prepare the cable:
• Push the cable gland over the cable.
• If there are multiple seals, select a seal that ts your cable
diameter. Seal ranges are: 8-12mm / 12-16mm / 16-21mm.
• Push the housing with seal over the cable.
• Strip 42mm from the cable.
• Strip 12mm from the conductors.
NOTE : Do not use PE pin when using connector with 4 core QD
Cable.
B) Connect the conductors to the contact carrier. Match the assign-
ment according to the label on the contact carrier.
WARNING: Ensure that the correct connection for Line, Neutral,
*
match according to the label on the contact carrier. In case of
mismatch, phase balance of system will be affected.
NOTE: For exible wires, we recommend using ferrules acc. to
DIN 46228 that are crimped with jointing clamp.
C) Torque the contact carrier screws to 1 Nm.
MALE
D) Push the contact carrier into the housing until it snaps in audibly.
E) Tighten the cable gland to a torque of 4.5 Nm.
WARNING: Observe the permitted bending radius during installation.
*
The degree of protection might fail if the bend radius is exceeded.

FIELD WIREABLE QD CONNECTORS - THREE-PHASE
DISCONNECT (if needed)
To disconnect Enphase Three-Phase Field Wireable QD Connectors,
release the two connectors by pressing down the snap with a screwdriver. You can then separate the connectors
* WARNING: Never plug in or disconnect the connectors under load.
The connectors are not suitable for interrupting the current.
SAFETY

for optimal system operation.
Safety Instructions
DANGER: Risk of electric shock. Do not use Enphase
+
equipment in a manner not specied by the manufacturer.
Doing so may cause death or injury to persons, or damage
to equipment.
DANGER: Risk of electric shock. Be aware that installation
+
of this equipment includes risk of electric shock. Do not use
without rst removing AC power from the Enphase System.
Disconnect the power coming from the photovoltaics
before servicing or installing.
DANGER: Risk of electric shock. Never plug in or disconnect
+
the connectors under load. The connectors are not suitable
for interrupting the current.
DANGER: Risk of electric shock. Risk of re. Before making
+
any connections verify that the circuit breakers are in the off
position. Double check all wiring before applying power.
DANGER: Risk of electric shock. Risk of re. Only use
+
electrical system components approved for wet locations,
including but not limited to conduit ttings.
DANGER: Risk of electric shock. Risk of re. Only qualied
+
