Installation Overview

The Product is an optical system that operates through precisely designed light reflections. Be careful not to bend the components when assembling and installing

the Product. Handle all the components with mirror surfaces by the edges or use gloves during installation to prevent finger printing. Installation includes the following

steps:

• Plan location

• Select power unit enclosure

• Plan power unit placement and cable routing

• Rough in cable

• Install power unit

• Install junction box (optional)

• Assemble Lightfalls fixture

• Mount Lightfalls fixture

• Make electrical connections

• Mount primary reflectors

To reduce risk associated

with fire: Only use the LED

driver(s) provided by 3M.

! WARNING

Installing the Product

Plan Location

• Identify the proposed location on wall or ceiling.

Select Power Unit Enclosure

Local ordinances require an electrical enclosure for the LED drivers. The size and

type of enclosure will depend upon where it is to be installed.

• Select a suitable metal enclosure, minimum dimensions 7.41" x 3.75" x 3.5"

(188.21mm x 95.25mm x 88.9mm) or 90 cu. in. for each LED driver.

• Mount the LED driver in the metal enclosure.

NOTE: The LED driver 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 driver with poor thermal contact may result in decreased

LED driver lifetime and void the warranty. If the LED driver case tempera-

ture is 70°C, there will be approximately 40% less light out of the fixture.

Table A. Maximum Run Length Between LED Driver and Junction Box

Plan Power Unit Placement and Cable Routing

• Select a location for the power unit satisfying local ordinances.

• Determine how the cables will be routed through wall or ceiling.

For fixture to power unit distance greater than 25 feet:

• Supply additional secondary wire (Figures 1 and 2, Page 4) between the

junction box and the LED driver.

• Determine the run length between the power unit and the junction box.

• Select the appropriate wire gauge for additional secondary wire between the

LED driver and junction 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 cable instead.

The Product operates on a Class 2 circuit and must be wired as in Figure 1 or

Figure 2 (Page 4).

IMPORTANT NOTE: To operate correctly, the wire distance from the LED

driver to the Lightfalls fixture must be within the maximum run length indi-

cated in Table A between LED driver and junction box.

Rough in Cable

• Rough in the cable as shown in the diagram in Figure 1 or Figure 2 (Page 4).

• If not using a dimmer and relay, cap off Dim+ and Dim– with wire nuts and

connect AC_L directly to ACL and AC_N directly to ACN on the LED driver.

Assemble Lightfalls Fixture

The Product can be partially assembled and installed in sections or completely assembled before it is installed, depending on the installer’s preference.

Many different lighting effects can be created, depending on how the components of the Lightfalls fixture are assembled. All fixtures consist of three basic

types of segments:

• Heatsink LED assembly segment (Figure 3).

• Virtual LED assembly segment (Figure 4).

• End mounts (Figure 5) - used for the arc configuration (Figure 6, Page 5) and ‘S’ configuration (Figure 7, Page 5). The circle configuration (Figure 8,

Page 5) does not require end mounts.

The heatsink LED assembly can be placed anywhere in the design to achieve different lighting effects. For example, if an asymmetrical distribution is

desired, the heatsink LED assembly can be located to one side of the configuration or the other, not in the middle position as shown in Figures 6, 7 and 8.

Typical Configurations

Arc Configuration (Three-Reflector Configuration)

• Using the hex driver and screws provided, assemble one heatsink LED

assembly segment (Figure 3) to form an arc (Figure 6) with end mounts

(Figure 5).

‘S’ Configuration (Five-Reflector Configuration)

• Using the hex driver and screws provided, assemble two heatsink LED

assembly segments (Figure 3) — one with a linear virtual LED plate — with

end mounts (Figure 5).

• Connect the segments to form an ‘S’ (Figure 7).

NOTE: The central virtual LED reflector has no mirror film and is painted

white, even when other fixture hardware is black. The white LED reflector

diffuses light, rather than continuing the light reflections.

Circle Configuration (Seven-Reflector Configuration)

• Using the hex driver and screws provided, assemble one heatsink LED

assembly segment (Figure 3 and Figure 4).

• Assemble two virtual LED assembly segments (Figure 4).

• Add one arc mounting bracket.

• Connect to form a circle (Figure 8).

NOTE: Does not require end mounts.

Mount Lightfalls Fixture

The Product is intended for mounting on a flat planar surface, such as a wall, and

may be mounted on a hard surface/cement or drywall ceiling.

• Mark the positions of the anchor points/screw locations.

• Install drywall/concrete anchors as applicable.

• Install the Lightfalls fixture to the anchor points with customer supplied

screws.

• Install the heatsink LED assembly and primary reflector standoff with

supplied hex screws.

• Some configurations may require two installers.

- Position the Lightfalls fixture against wall or ceiling.

- Install the mounting plates as shown in Figure 9 using the recommended

#6 pan head screws and appropriate wall anchors. The end mount (screw

with screw cap) is shown in Figure 10.

- Install the remaining mounting plates (#6 pan head screws and

appropriate wall anchors) to complete the configuration.

- Install the secondary reflectors (with magnet) on the mounting plates

(Figure 11).

Make Electrical Connections

Connect the wire harness to the Lightfalls fixture.

Mount Primary Reflectors

• Mount the primary reflector onto the primary reflector standoffs as shown

(Figure 12 and Figure 13), the high sides of the reflector oriented left and

right. NO TE: The reflective surface can be easily damaged. Take care not

to scrape the tips of the metal standoff against the inside surface of the

primary reflector.

- Press with enough force to snap the reflector into place on the reflector

standoff.

Before Energizing the Circuit

Ensure that the cabling is secure, the connections are tight and the length of cable between the Lightfalls fixture and power unit is within the maximum

for the gauge of wire used.

Component Replacement

The power unit may be serviced by an electrician. Replacement Lightfalls fixtures

and accessory kits can be ordered from 3M. For ordering information for full mount-

ing kits, please see the Lightfalls by 3M + Todd Bracher Specification Sheet or go to

www.3Marchitecturalmarkets.com.

Handling, Cleaning and Repairing

Handling

Handle the Lightfalls fixture with care. This assembly can be damaged if improperly or roughly handled. Keep the Product in its original packaging until

installation, and if feasible, transport the Product to the site in its original box. Handle all the components with mirror surfaces by the edges or use gloves

during installation to prevent finger printing.

Cleaning

If needed, use a mild, non-abrasive, water-based detergent solution to clean main reflectors. Plastic polishes may also be used. DO NOT use solvent-

based, ammonia-based cleaning solutions or glass cleaners. These may mar or discolor the transmissive lens. The flat secondary reflector plates may be

cleaned with glass cleaner. This same recommendation applies to the non-reflector side (acrylic), however, this side can be repaired of light scratches

using acrylic polishing compounds.

Repairing

Except for replacing the replaceable components, DO NOT attempt to repair the Lightfalls fixtures, which do not have user-serviceable parts.

Troubleshooting

If the solutions below do not work for you, please call 3M Technical Service at 1-888-650-3497.

Table D. Troubleshooting

Related Documentation

Please refer to the Lightfalls by 3M + Todd Bracher Specification Sheet for product specifications and ordering information.

Problem Potential Cause What to Do

LED does not illuminate

LED driver does not have AC input Make sure light switch or other control relay is on and/or breaker is on.

Secondary side open circuit Find and fix open connection. If the Output Voltage from the LED driver is 36V, but there is no light coming from the LED, there is likely an open circuit. Make sure connectors are properly seated.

Secondary side short circuit or reverse connection

Find and fix short circuit. If the Secondary LED wiring is shorted together or connected back-wards, the LED driver should read near 0V. The connector at the fixture can be forced in back-wards. Make sure the connector 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 replaced. Remove load before measuring LED driver output, because a short on the secondary side can make the LED driver seem broken.

LED driver 0–10V control wiring shorted

Find and fix short.

LED does not dim Control wiring open Find and fix open.

Light does not illuminate full fixture

A primary reflector is misoriented by 90 degrees

Check all primary reflectors for correct orientation.
