Installation O er iew
The Produ t is an opti al system that operates through pre isely designed light refle tions. Be areful not to bend the omponents when assembling and installing
the Produ t. Installation in ludes the following steps:
•Plan lo ation
•Sele t power unit en losure
•Plan power unit pla ement and able routing
•Rough in able
•Install power unit
•Install jun tion box (optional)
•Assemble and install the Lightfalls fixture
•Orient and mount primary refle tor
Installing the Product
To reduce risk associated
with fire: Only use the LED
driver(s) provided by 3M.
!WARNING
Plan Location
•Identify the proposed lo ation on wall or eiling.
Select Power Unit Enclosure
Lo al ordinan es require an ele tri al en losure for the LED drivers. The size and
type of en losure will depend upon where it is to be installed.
•Sele t a suitable metal en losure, minimum dimensions 7.41" x 3.75" x 3.5"
(188.21mm x 95.25mm x 88.9mm) or 90 u. in. for ea h LED driver.
•Mount the LED driver in the metal en losure.
NOTE: The LED dri er has a maximum case temperature of 70°C (158°F)
and begins derating 20%/10°C at 50°C. Undersizing the enclosure or
mounting the LED dri er with poor thermal contact may result in decreased
LED dri er lifetime and oid the warranty. If the LED dri er case tempera-
ture is 70°C, there will be approximately 40% less light out of the fixture.
Table A. Maximum Run Length Between LED Dri er and Junction Box
Plan Power Unit Placement and Cable Routing
•Sele t a lo ation for the power unit satisfying lo al ordinan es.
•Determine how the ables will be routed through wall or eiling.
For fixture to power unit distan e greater than 25 feet:
•Supply additional se ondary wire (Figure 1, Page 4) between the jun tion box
and the LED driver.
•Determine the run length between the power unit and the jun tion box.
•Sele t the appropriate wire gauge for additional se ondary wire between the
LED driver and jun tion box using Table A. Column 3 of Table A displays the
maximum run lengths with a shortened wire harness less than or equal to 5
feet. One reason to shorten the wire harness would be to run plenum-rated
or riser-rated able instead.
The Produ t operates on a Class 2 circuit and must be wired as in Figure 1 (Page
4).
IMPORTANT NOTE: To operate correctly, the wire distance from the LED
dri er to the Lightfalls fixture must be within the maximum run length indi-
cated in Table A between LED dri er and junction box.
Rough in Cable
•Rough in the able as shown in the diagram in Figure 1 (Page 4).
For installations without a dimmer and relay:
•Cap off Dim+ and Dim– with wire nuts and onne t AC_L dire tly to ACL and
AC_N dire tly to ACN on the LED driver.

Assemble and Install the Lightfalls Fixture
The Produ t is intended for mounting on a flat planar surfa e, su h as a
wall or eiling. It may be mounted on various hard surfa es in luding
ement and drywall. The a ompanying figures depi t one suggested ori-
entation.
1. Choose the lo ation and orientation for the Lightfalls S on e.
2. Mark the positions for the s on e bra ket an hor point/s rew
lo ations.
3. Mark the position for the thi k panel bushing lo ation for wire routing.
4. Install drywall/ on rete an hors as appli able and the thi k panel
bushing (See Figure 2).
5. Install the S on e Bra ket to the an hor points with ustomer supplied
s rews (See Figure 3).

Orient and Mount Primary Reflector
•Align the slots in the primary refle tor with the primary refle tor
standoff as shown (Figure 7), with the high sides of the refle tor
aligned with the Heatsink/LED assemblies.
NOTE: The reflecti e surface can be easily damaged. Take care
not to scrape the tips of the metal standoff against the inside sur-
face of the primary reflector.
•Press with enough for e to snap the refle tor into pla e on the
refle tor standoff. To produ e a different lighting effe t, re-install
the refle tor rotated by 90°.

Before Energizing the Circuit
Ensure that the abling is se ure, the onne tions are tight and the length of able between the Lightfalls fixture and power unit is within the maximum
for the gauge of wire used.
Component Replacement
The power unit may be servi ed by an ele tri ian. Repla ement Lightfalls fixtures
and a essory kits an be ordered from 3M. For ordering information for full mount-
ing kits, please see the Lightfalls by 3M + Todd Bra her Spe ifi ation Sheet or go to
www.3Mar hite turalmarkets. om.
Handling, Cleaning and Repairing
Handling
Handle the Lightfalls fixture with are. This assembly an be damaged if improperly or roughly handled. Keep the Produ t in its original pa kaging until
installation, and if feasible, transport the Produ t to the site in its original box.
Cleaning
If needed, use a mild, non-abrasive, water-based detergent solution to lean main refle tors. Plasti polishes may also be used. DO NOT use solvent-
based, ammonia-based leaning solutions or glass leaners. These may mar or dis olor the transmissive lens. The flat se ondary refle tor plates may be
leaned with glass leaner. This same re ommendation applies to the non-refle tor side (a ryli ), however, this side an be repaired of light s rat hes
using a ryli polishing ompounds.
Repairing
Ex ept for repla ing the repla eable omponents, DO NOT attempt to repair the Lightfalls fixtures, whi h do not have user-servi eable parts.
Troubleshooting
If the solutions below do not work for you, please all 3M Te hni al Servi e at 1-888-650-3497.

Problem Potential Cause What to Do
LED does not illumi-
nate
LED driver does not have
AC input
Make sure light swit h or other ontrol relay is on and/or breaker is on.
Se ondary side open ir uit Find and fix open onne tion. If the Output Voltage from the LED driver is 36V, but there is no light oming
from the LED, there is likely an open ir uit. Make sure onne tors are properly seated.
Se ondary side short ir uit
or reverse onne tion
Find and fix short ir uit. If the Se ondary LED wiring is shorted together or onne ted ba kwards, the LED
driver should read near 0V. The onne tor at the fixture an be for ed in ba kwards. Make sure the onne tor
is in the keyed orientation.
LED driver does not have
>30 V DC output
If input AC is supplied but DC output voltage is not supplied, the LED driver needs to be repla ed. Remove load
before measuring LED driver output, be ause a short on the se ondary side an make the LED driver seem
broken.
LED driver 0–10V ontrol
