PREPARATION
For full installation instructions for the Enphase IQ 8D Microinverters, read and follow
all warnings and instructions in this guide and in the Enphase IQ 8D Microinverter
Installation and Operation 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 3.5mm (recommended disconnect tool)
• 30mm wrench
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-300 center tap adapter to center-feed the branch circuit with an AC connection
• Use mated pairs of connectors to connect with a remote part of the array

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,
Earth 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.
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.
A) Prepare the cable:
• Push the cable gland over the cable.
• If there are multiple seals, select a seal that ts your cable
diameter.
• Push the housing with seal over the cable.
• Strip 50mm from the cable.
• Shorten conductors N, L1, L2, and L3 by 8 mm, but keep PE (ground)
at 50mm.
• Strip 12mm from the conductors.
ASSEMBLY

SAFETY
IMPORTANT SAFETY INSTRUCTIONS.
SAVE THIS INFORMATION.
Follow all safety and assembly instructions when installing En-
phase Three-Phase Field Wireable QD Connectors.
DISCONNECT (if needed)
To disconnect Enphase Three-Phase Field Wireable QD Connectors,
release the two connectors by pressing down the snap with a screw-
driver. 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 Instructions
+DANGER: Risk of electric shock. Do not use Enphase equipment in a manner not specied 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 qualied personnel should install, troubleshoot, or replace the En-
phase Three-Phase Field Wireable QD Connector.
+DANGER: Risk of electric shock. Improper use of the Three- Phase Field Wireable QD Connector or its components may
result in a shock, re or explosion. To reduce these risks,
disconnect all wiring before attempting any maintenance.
+DANGER: Risk of electric shock. Risk of re. Ensure that all AC and DC wiring is correct and that none of the AC wires
are pinched, shorted, or damaged.
+DANGER: Risk of electric shock. Risk of re. Do not attempt to repair or alter the Enphase Three-Phase Field Wireable
