IQ system Controller 2 Installation

Install the wall-mount bracket
A ) Mark a plumb line over the wall stud as a guide.
* WARNING! Multiple risks. Make sure not to drill or attach into
electric wiring or pipes that are in the wall!
B ) Remove the wall mount bracket only from the shipping box.
C ) Place the wall-mount bracket on the wall so that the mounting holes in
the middle of the bracket align with the center of the stud. Use a level
to keep the bottom of the wall-mount bracket level.
D ) Use the #10, 1/4”, or 5/16” wood screws (or masonry attachments
if installing in masonry) to attach the bracket using one screw and
washer for each slot. The slot size of the IQ System Controller 2
wall mount bracket is 8.5mm. Use an appropriately sized washer for
each of the screws, and check with a structural engineer and local
standards for local requirements.
E ) Verify that the wall-mount bracket is level, solidly attached to the wall,
and oriented for upright installation of the IQ System Controller 2.
* WARNING! Risk of injury and equipment damage. Do not mount
an IQ System Controller 2 on a bracket that is not properly attached to
a wall.
* WARNING! Risk of injury and equipment damage. Protect the IQ
System Controller 2 from impact damage and improper use.

D ) Repeat on the other side with the second handle.
* WARNING! Risk of injury and equipment damage. Two persons
are required to lift the IQ System Controller 2.
E ) Use the lifting handles, take the IQ System Controller 2 from the
packaging, making sure it is top side up (upright). IQ System Controller
2 is designed only for vertical installation without inclination (must be
level).
F ) Lift the IQ System Controller 2 slightly above the installed wall mount
bracket and allow it to slide down so that the bracket facing hooks set
into both the top and bottom shelves of the wall mount bracket.
G ) Allow the IQ System Controller 2 to slide down until the IQ System
Controller 2 is fully seated on the wall-mount bracket shelf.
* WARNING! Risk of injury and equipment damage. Do not release
the IQ System Controller 2 until you ensure that the IQ System Control-
ler 2 is fully seated in the wall-mount bracket shelf.
H ) For each handle, pull the plunger tabs
to release them and remove the lift
handles.
I ) Reserve the handles for the next
installation.
J ) On the bottom handle mounts, use the
two provided partial-threaded custom
M6 screws to secure each side of the IQ
System Controller 2 and tighten to 0.5
N•m (4.4 lb•in) or less.
The threaded portion of the screw
engages with the bracket, while the un-
threaded portion of the screw engages
with the hole in the bracket to prevent
vertical movement of the bracket.
* WARNING! Risk of injury and
equipment damage. Do not skip this
step. Without these screws in place,
the IQ System Controller 2 may fall and
cause injury or damage if bumped or
shaken.
K ) Use the four ller plates, provided in the lit kit, to cover the screws.

codes.
Install breakers as needed for the AC grid, main load, Enphase IQ Combin-
er, Enphase IQ Batteries, and generator(optional). These breakers are not
included and must be ordered separately.
NOTE: You must install a backup loads breaker if required by local code.
* WARNING! Risk of injury and equipment damage. Use only the
breakers listed in this table.
