Installation Procedure

1- Using the included C-ring or the dimensions provided, trace a cutout pattern onto the
ceiling surface.
2- Cut the mounting hole. Use a sharp tool to avoid stressing or cracking the mounting sur-
face.
3- Pull the wires through the hole.
4- Pass the two suspended ceiling support brackets through the hole and place as shown
in the illustration. Make sure the part of the bracket that is flat against the tile is toward
the hole. If installing in a non-suspended ceiling application, these brackets are not
required.
5- Pass the C-ring bracket through the hole. Slide the cutout slot into the hole first, and
EN
then rotate the bracket so it passes through the hole. Be sure the wires pass through the
ring.
6- Position the support brackets, and secure the C-ring bracket to each of the support
brackets using the screws provided. If installing in a non-suspended ceiling application,
skip this step.
7- Loosen the connection cover plate retaining screw and swing the cover open. Install an
fitting into the hole provided on the cover plate.
8- Temporarily support the enclosure so the wires may be passed through the enclosure
top with enough slack to prepare and terminate the wires.
9- Locate the terminal block connectors included with the loudspeaker. Loosen the wire
retaining screws fully.
10- Strip the wire ends approximately 10 mm (0.4") and insert each wire into its proper
connector position. Tighten the wire retaining screws fully.
11- Rotate the connection cover plate closed, making sure not to stress the connections or
pinch the wires. Tighten the cover plate's retaining screw.
12- Adjust the wiring at the entry point, if necessary, and properly secure fitting. This pre-
vents wire stress and strain from pulling the connections/connectors loose.
13- Attach a safety cable (secondary support cable) from the enclosure's attachment tab
to an appropriate support point. This cable and the attachment points must be strong
enough to support many times the weight of the loudspeaker in the event the primary
mounting system fails.
14- Insert the enclosure into the ceiling cutout, making sure any brackets used remain
properly positioned. Tighten the loudspeaker's mounting clamp screws.
15- Set the tap selector switch to the desired position. 70V systems, all four positions may
be used. Do not use highest tap setting with 100V systems. 8 ohm systems, selector to 8
ohm position.
16- Make sure all tests and adjustments are complete before installing the grills. Locate
the loudspeaker's grill. The cabinet and the grill both have a small loop of plastic line.
Using the clip on the grill's line, attach the grill's safety loop to the cabinet's loop. Care-
fully work the grill into its retaining slot and press firmly into place. Work the grill in
slowly and evenly to avoid damage. Make sure all tests and adjustments are complete
before installing the grills.
