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.

DISCONTINUED

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.
