Power Determination; Wiring; Installation In Back Cans Without Conduit; Figure 20. Non-Conduit Guided Wiring To Can And Wire Restraint - Community Distributed Design D4LP Installation And Operation Maintenance Owner's Manual

Note: Here we describe wiring of the loud-
speakers in the cans, including connection to
the cans and between can and loudspeaker.
Because in some cases cans are installed first,
and the loudspeakers are installed immedi-
ately thereafter, whereas in other situations
the cans are pre-installed including the facility
wiring to the can, there is no "perfect" single
order in which to present these topics. We de-
scribe the actual mounting of the can into the
ceiling (or wall) after we describe the general

ries loudspeakers. The directions include as-
sistance to those installers using a complete
Community package of loudspeakers and ac-
cessories, including the back cans, grilles, tile
rails and so forth. We include instructions
for use of optional Community Distributed
Design Series retrofit adapters so that Com-
munity Distributed Design Series loudspeak-
ers can be mounted in other manufacturer's
cutouts and/or back cans. If accessory
products from a different manufacturer are
used, please refer to the installation manuals
supplied with those products.

to specially select different wire terminals
for 8-ohms or for various 70-volt and 100-
volt power taps. Instead, a face-mounted
tap switch allows you to make this selection.
Once the loudspeaker is mounted correctly
in the ceiling, set the tap switch to the appro-
priate tap setting before any audio is passed
through the loudspeaker. Do not change the
setting on the tap switch while the loud-
speaker is in use.
The only tool required is a screwdriver,

package. Distributed Design back cans
include a swivel-out terminal access cover
that also serves as a cable clamp when
tightened in place. The terminal block in the
can's outer recess has two (+) connections
and two (-) connections. If you're only
connecting one (dual conductor) cable,
you can use either (+) and (-) terminal,
as illustrated in Figure 20. If you're daisy-
chaining a cable to the next can, you can
