Installation Guidelines For Center Feeding (Qd-12-42-63 Landscape Ballast Pv Orientation); Figure 11: Center Feeding Of Ac Branch Circuit For Installations With Qd-12-42-63 (15.1 Ft) - enphase IQ8D-72-E-US Design Manual

Installation Guidelines for Center Feeding (QD-12-42-63 Landscape Ballast PV Orientation)

• The QD-12-42-63 cable includes a center-tapping
connector in an alternating pattern after sequences
four and five connectors as shown in Figure 10. So
there are two center tap connectors available for
branch of 9.
• When installing IQ8D Microinverter system using
QD-12-42-63 cable; select the center tap connector
such that a maximum of 6 IQ8D Microinverters are
installed on one side of center tapping connector so
that the voltage rise to the farthest Microinverter is
maintained <1%.
NOTE : When using QD-12-42-63 for installations ; few of
the center tap connectors shall remain unused based on
system configuration. Do not remove pre-installed sealing

caps on the center center tap connector, if the connector is
not used for center feeding using Center Tap Adapter Cable
(QD-LINKFW-10).
• Use a center tapping adapter cable (QD-LINKFW-10) to
connect the center-tapping connector to the extension
cable to PV sub panel cable using a male three phase
field wireable connector (QD-CONN-10M).
• Provide an AC connection from the three-phase field
wireable connectors to the three phase 208V grid
supply using equipment and practices as required by
local jurisdictions.
