Recommended Wiring
• 18AWG,stranded,2conductors.
Note: Some ceilings are rated for use as a plenum return for heating and cooling. In these areas, you must use plenum type cable or conduit to pass
building inspection. Consult with local building code enforcement to determine the requirements of each job.
General Guidelines

enough to allow you to connect it to the loudspeaker either on the ground or at the top of the ladder before you install the
speaker in the grid.
2.Striptheinsulationoneachconductorbackapproximately1/2inch.Attachyourspeakerwiringsignal(+)wiretothered

Note: If using conduit connectors other than what is provided, loosen, but do not remove, the screws holding the access plate and slide the plate
up to detach it from the speaker assembly. Attach the access plate to the new conduit ttings before joining the wiring, then re-attach the cover plate.
3.Pushtheconnectionsintothespeakermakeupcavity.
Note: Do not use the back plate cavity as a junction for wiring that is not powering the speaker!
