Install conduit and field wiring, continued
+
DANGER!
Risk of electric shock. Check that the dedicated circuit
breaker protecting the branch where the IQ Battery(ies) will be
connected is turned off before wiring.
*
WARNING!
Risk of equipment damage. The DC switch must be
OFF before installing, otherwise IQ Battery will try to form a grid.
D )
If installing an IQ Battery 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 field 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 flat 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 fit the O-ring (red) of the raceway. Make
sure that the O-ring is captured in the groove between the IQ Battery
enclosure and the raceway flange adjacent to the O-ring.
E ) Using the conductors and suitable conduits, connect the AC dis-
connect and the first adjacent IQ Battery. Use the conduit openings
provided to connect the conduit and pass the wires through them.
Note that if an Enphase IQ System Controller 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 field wiring
compartment.
*
WARNING!
Risk of equipment damage. Always connect to two
Lines (active) and one ground.
F ) Connect each wire in the field 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 IQ Battery 10
, route the wires from the first IQ Battery
to the adjacent IQ 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 IQ Battery 3 or two IQ Battery 10 on a single branch
circuit.
H ) After all wires in the field wiring compartment are connected and
secured, check that there are no exposed conductors.
I ) If connecting additional IQ Batteries, use another conduit and another
set of wires to connect between field wiring compartments.
J ) Gently arrange all the wires and connectors inside the field wiring
compartment.

K ) Plug any unused conduit openings before proceeding.
L ) Replace the field 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.
Inter-unit
raceway
Correctly installed
inter-unit raceway
Grommet to be installed on the left
side or right side when the hole in the
left side or right side is not used for
cable routing.
(To be used in IQ Battery 3 when no
conduit is used with the hole).
(To be used in Right most Base unit in
IQ Battery 10 when no conduit is used
with the hole).
Dismounting of IQ Battery 3 Cover
A) Remove the conduit covers from either sides of the IQ Battery 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 cover, make sure that the indicated
snaps at the bottom of the unit are being unlocked.
F) Simillarly for dismounting the IQ Battery 10 Cover, please follow the
instructions from A to E.
