Installation Instructions
The installation of the Class R reflector kit Type II shall be performed by qualified personnel by completing the steps listed below.
This retrofit kit will consist of:
(1) end bracket/ballast assembly prewired with ballast and sockets mounted (ballast will be Class P with UL approvals and wiring diagram on label)
(1) splice box
(2) reflectors
(1) trim assembly and mounting hardware consisting of:
(2) quarter-turn fasteners
(60) #8 self-drilling TEK screws
Job packs will have screws bulk-packed with each pallet of kits.
Verify the contents of the retrofit kit by using the diagram below.
End Brackets/Splice Box Reflectors Trim

Remove existing components from host fixture.
Locate the fluorescent lighting fixture that is to be retrofitted. Turn off power.
WARNING: Electrical shock can occur during retrofit component installation if power is not turned off.
WARNING: Installation of this retrofit assembly requires a person familiar with the construction and operation of fluorescent luminaire electrical system and the hazard involved.
WARNING: Unless otherwise indicated, do not make or alter any opening in the compartment of wiring or electrical components during installation of this retrofit assembly.
WARNING: Ensure that existing fixture is and remains properly connected to building ground.
Use of any other than Lithonia Lighting supplied screws to install assembly may result in ungrounded fixture components.
Remove existing louver, lamps and channel cover. Identify power supply wires to disconnect. Follow installation step
2 wiring option A or B based on incoming supply wire. Remove ballast, sockets and lampholder bracket. Recycle or properly dispose of all components removed from host fixture.
Step Two:
Install relight assembly.
Install end brackets to 2’ length (socket side) of fixture. Install end bracket assembly by inserting bottom flange between bottom of fixture end plate and tee-bar. Center end bracket and attach using two 8-32 self-drilling TEK screws through the small holes at the top of the bracket (provided). Repeat on opposite end of fixture as shown.

Optional Step:
The 2 RT 8 RT/ 2 RT 5 RT Relight Assembly is shipped with two flexible reveal cover trim pieces. Some installations in existing lensed troffers can leave unsightly gaps between the side rail of the Relight door frames and the existing housing, which can leave old hinge and latch points exposed. The trim kit is designed to cover these to insure an attractive installation.
To install, slide the ends of the trim piece under the Relight end brackets as shown in in the photo. When they are fully in place, slide the notch of the trim piece towards the end bracket to fully seat the part. The part is flexible so this step can typically be completed either before or after full installation of the Relight assembly.
