3 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! WARNING To reduce risk associated with fire: Only use the LED driver(s) provided by 3M. 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 temperature 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 Wire Gauge (AWG) Distance with 25 ft. harness Distance with harness cut to 5 ft. or less 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 indicated 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. Table B.

5 Installing the Product (cont.) 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). 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.

8 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 mounting kits, please see the Lightfalls by 3M + Todd Bracher Specification Sheet or go to Table C. Replaceable Components Replacement Parts LED heatsink assembly, linear LED heatsink assembly, circular Secondary Reflector Plate LED Driver Order Code LF-HSL-XX-XX LF-HSC-XX-XX LF-RP LF-PSU 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 solventbased, 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 Table D. Troubleshooting Problem Potential Cause What to Do LED does not illuminate LED driver does not have AC input Secondary side open circuit Secondary side short circuit or reverse connection LED driver does not have >30 V DC output LED driver 0 10V control wiring shorted Make sure light switch or other control relay is on and/or breaker is on. 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. Find and fix short circuit. If the Secondary LED wiring is shorted together or connected backwards, the LED driver should read near 0V. The connector at the fixture can be forced in backwards. Make sure the connector is in the keyed orientation. 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. 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.
