interconnect bracket. It is recommended to screw the zip ties close to the power cable connection to ensure
that the power cable remains secure.
14. Connect field wiring and test loudspeaker operation. It is recommended to keep the loudspeaker assembly in
the 90 degree orientation until loudspeaker operation has been tested, to allow easier access the connection
panel and indicator lights.
15. Rotate the loudspeaker assembly into the desired position.
16. If installing the loudspeaker perpendicular to the wall, insert flanged head bolts into both holes on the
bottom wall bracket, to secure the loudspeaker bracket to the wall bracket. Place washers between the
loudspeaker bracket and the wall bracket.
If installing the loudspeaker at an angle that is not perpendicular to the wall, attach the yaw bracket to the
loudspeaker and wall bracket to lock the speaker into position. The yaw bracket secures the loudspeaker
array into position, in 6° increments (from 12° to 90°).
a. Attach the yaw bracket to the wall bracket, using the included flanged head bolt.
b. Attach the yaw bracket to the loudspeaker bracket, using the included flanged head bolt.
17. Tighten the flanged head bolts and flanged nuts connected to the loudspeaker brackets at the top and
bottom of the array, using a torque not to exceed 6.78 N-m (5 ft-lbs).
