Installation Manual

Install conduit and eld wiring, continued
+ DANGER! Risk of electric shock. Check that the dedicated circuit
breaker protecting the branch where the Encharge Battery(ies) will
be connected is turned off before wiring.
* WARNING! Risk of equipment damage. The DC switch must be
OFF before installing, otherwise Encharge will try to form a grid.
D ) If installing an Encharge 10, install the inter-unit raceways. The
left-side and right-side conduit openings are different diameters, so
you must install the raceway in the proper direction.
•
Face the fronts of the batteries,
and insert the raceway through
the right-hand unit’s left-side
conduit opening from within
the eld wiring compartment,
with the arm of the raceway
pointing up.
•
Push the raceway through the right-hand unit’s left-side conduit
opening and into the left-side unit’s right-side conduit, opening until the
two snap features on the raceway engage the left-side unit’s enclosure.
•
Once fully inserted, rotate the “arm” toward you until it stops.
•
The left-side conduit opening of each battery unit has a at surface,
without additional features. The larger seal (green) on the raceway
mates with this opening. The right-side conduit opening has a
groove around the hole to t the O-ring (red) of the raceway. Make
sure that the O-ring is captured in the groove between the Encharge
enclosure and the raceway ange adjacent to the O-ring.
E ) Using the conductors and suitable conduits, connect the AC
disconnect and the rst adjacent Encharge Battery. Use the conduit
openings provided to connect the conduit and pass the wires through
them. Note that if an Enphase Enpower is in line-of-sight, the breaker
can service as a disconnect.
* WARNING! Risk of equipment damage. Do not modify or rewire
the pre-installed wiring or bonding connections in the eld wiring
compartment.
* WARNING! Risk of equipment damage. Always connect to two
Lines (active) and one ground.
F ) Connect each wire in the eld wiring compartment to its correspond-
ing conductor (Lines and Ground). Each terminal accepts two 14-8
AWG conductors (11mm/7/16 inch strip length). Tighten to 14 lb-in.
G ) If installing an Encharge 10, route the wires from the rst Encharge
Battery to the adjacent Encharge Battery through the inter-unit
raceway. There are two positions for each line and for ground in the
terminal block to allow for daisy-chaining.
* WARNING! Risk of equipment damage. Do not daisy chain more
than six total Encharge 3 or two Encharge 10 on a single branch
circuit.
H ) After all wires in the eld wiring compartment are connected and
secured, check that there are no exposed conductors.
I ) If connecting additional Encharge Batteries, use another conduit and
another set of wires to connect between eld wiring compartments.
J ) Gently arrange all the wires and connectors inside the eld wiring
compartment.

K ) Plug any unused conduit openings before proceeding.
L ) Replace the eld wiring compartment cover. Use a cross-head
screw driver to tighten the cover screws to 2.3Nn (20.3 Ib-in).
* WARNING! Risk of equipment damage. Ensure that no wires are
pinched before replacing the cover.

DANGER! Risk of electric shock. The system is not ready to
be energized! Do not close the circuit breaker or turn on the DC
switch.

Correctly installed
inter-unit raceway
Grommet to be installed
when the hole in the indicat-
ed location is not used for
cable routing.
(To be used in En 3 when
no conduit is used with this
hole).
(To be used in Right most
Base unit in En 10 when no
conduit is used with this
hole).
Dismounting of EN 3 ID Cover
A) Remove the conduit covers from either sides of the ID cover
B) Lift up the ring of the quarter turn screw.
C) Turn the ring in the anticlockwise direction to unlock the screw.
D) After unlocking, hold the ring of the screw and lift the top cover
up slightly and pull it away from the wall in the indicated direction.
E) While pulling out the ID cover, make sure that the indicated
snaps at the bottom of the unit are being unlocked.
F) Simillarly for dismounting the EN 10 ID Cover, please follow the
instructions from A to E.
