Make wire connections and ground assembly to host fixture per option A or B based on existing fixture supply wire.
Option A and B (see photos on next page)
Optional Step:
The 2RT8RT/2RT5RT 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.

Install reflectors by inserting notched
end of the reflector past lance in end
bracket assembly and then rotating
opposite end (end accepting twist-
lock fasteners) into fixture.
Shift reflector until notches are locked
in place under lance and attach using
a quarter-turn fastener twisting tabs
that protrude through the reflectors
(spacers). Rotate second reflector
180° and repeat installation steps.
Install lamps. Use center slot in
housing to clear lamp pins.
Install trim assembly by inserting
hinge into slot of end bracket and
sliding back into the corner. Repeat
with opposite hinge, swing louver
closed and rotate latches into
locked position.
Trim hinges and latches from either side. Simply slide hinge into slot’s universal bracket assembly, close door and engage
cam latches.
Help save our environment by recycling all remaining components.
Save these instructions.
