1. Bend brackets as shown in Detail “A”. Install the

fixture in the ceiling using mounting channels or bar

hangers (B6, B24, or by others) placed in the

adjustable mounting brackets. Mount the fixture in

the ceiling so that the weight of the fixture is

supported by the mounting channel or bar and/or

hanger wires secured to the building structure.

2. Adjust the fixture so the bottom edge of the plaster

flange opening is flush with the finished ceiling line

and in alignment with adjacent fixtures. Secure

mounting brackets by tightening wing nuts on either

side of the fixture.

3. Remove and discard the wire twist around the

J-Box covers. Remove J-Box cover plate.

Remove appropriate knockout and assemble

Connect 120V or 277V supply wire to the respec-

tive 120V or 277V fixture wire. Use certified wire

nuts. Reinstall J-Box cover.
WARNING: DO NOT pinch wires between

J-Box/ballast cover and J-Box. Consult a

Qualified Electrician for all other options that

require other wiring configurations.
