INSTALLATION
USING EXISTING SOCKETBAR PLATES
-
Verify the fluorescent fixture is a 4ft or 8ft strip fixture of appropriate dimensions as shown in . For fixtures that are connected together in series on the same branch circuit, identify the section to be retrofitted.
-
Disconnect power to the fixture.
-
Remove existing linear fluorescent lamps as shown in . Dispose of lamps per local regulations.
-
Locate the ¼-turn fasteners as shown in and remove the cover panels on both strip light sections and discard.
-
Remove the socket mounting plate by gently prying outward on the housing using a large flathead screwdriver. and . For some strip light models the lampholder sockets can be removed without removing the socket mounting plate. See steps – .
-
Remove the sockets from the mounting plate as shown in .
-
Replace mounting plate making sure that the holes are in the same orientation as when removed. Insert the tab on the mounting plate into the slot in the housing as shown in . Gently pry the housing outward with a large flat head screw driver as shown in and insert the tab of the mounting plate into the slot in the housing. Note the correct orientation of the holes in the mounting plates in .
-
Repeat steps 5, 6, and 7 for the remaining 3 socket mount plates.
-
Cut the branch circuit wires at the connection to the fluorescent ballast leads in both strip light housings (if ballasts exist in both housings) as shown in .
-
Remove the ballast(s) by removing the mounting screw and dispose of properly per local regulations. See .
-
Remove the Linear Retrofit Assembly from the packaging. There are one of two panel assemblies: one with a driver and module and one (LRA28 only) with a module only. For 4’ retrofits, skip to . For 8’ retrofits locate the panel with the module only. Mount and position this assembly to the fixture section furthest from the branch circuit splice connections with the blue and red leads facing the center of the fixture – See . For LRA14 kits go straight to .
-
Insert the ends of the lanyards at each end of the panel assembly into the indicated holes as shown in and . Allow the assembly to hang by the lanyards as shown in . For LRA14 kits skip to .
-
Route blue and red leads through the center of the fuxture as shown in .
-
Lift the panel such that the lanyards at each end feed through the holes in which they were inserted, as shown in .
-
Touse the 1/4 – turn fasteners, firstremove the knockout. Secure the panel assembly in place onto the strip light housing, and fasten to the lampholder mounting plates with the ¼-turn fasteners located at each end of the assembly as shown in and . For alternate mounting using the drill-point screws provided, see Step 21A
-
Locate the remaining panel assembly with the driver. Position the panel assembly for ease of connection to the branch circuit wiring in the fixture as shown in .
-
nsert the ends of the lanyards at each end of the panel assembly into the indicated holes as shown in as done with the previous panel assembly. Allow the assembly to hang by the lanyards.
-
Locate the red and blue lead wires with the orange 3- position push-in connectors attached and locate the red and blue lead wires from the other tandem LRA panel assembly previously installed. Push the blue wire into the connector with the other blue wires and the red wire into the connector with the other red wires as shown in and .
-
Locate the Luminaire Disconnect with the ground wire connected. Secure the ground wire to the equipment grounding conductor in the luminaire or to the luminaire housing in accordance with the National Electrical Code (NFPA 70). See . A ground screw is provided with the kit if needed.
-
From the branch circuit wires strip about 0.40 inches of insulation. Insert the white branch circuit wire into the white hole of the Luminaire Disconnect and the black wire into the black hole. See .
-
Lift the panel such that the lanyards at each end feed through the holes in which they were inserted as performed with the previous panel assembly as shown in . Secure the panel in place using the ¼-turn fasteners at each end of the panel.
USING ADJUSTABLE MOUNTINGBRACKETS
-
Verify the fluorescent fixture is 8 ft strip fixture of appropriate dimensions as shown in .
-
Disconnect power to the fixture.
-
Remove fluorescent components including:
-
Attach center bracket Locate large bracket at center of 8 foot fixture .
Note: Be sure all existing wiring is above bracket. Center bracket and use fixture as guide to bend to correct width . Once bracket us bent to size secure with #8 drill point screw (supplied separately) on either side of fixture.
-
Attach end brackets. Locate bracket align with end of fixture Ensure tether hook features point inboard . Center bracket width and use fixture as guide to bend to correct width . Once bracket us bent to size secure with #8 drill point screw (supplied separately) on either side of fixture . Repeat at outer end of fixture.
-
Suspended panels from tethers by inserting “T” end of captive tether into hook features in brackets at both ends of panel .
-
Repeat steps 4-6 for secondary panel.
-
While panels are suspended make the following connections: Connect primary module ground lead to existing fixture ground screw . Ground lead position may be moved to alternate location .
-
Before making connection route all wire over brackets to ensure panel seats properly ( ). Connect red and blue leads from secondary panel to orange push in connectors from driver) and .
-
Connect incoming power with luminaire disconnect plug on driver input (black and white)( ).
-
Lift panel into place and secure with captive ¼ turn panel fasteners. Repeat for second panel
DRIVER PROGRAMMING
Driver output currents can be programmed at different levels to change the system’s light output and input power. The driver currents must be programmed within the ranges shown in the table below:
