WIRING AND ELECTRICAL SAFETY
All standard R.15 and R.35 loudspeakers are provided with two methods of connecting
the amplifier to the loudspeaker: a standard NL4-type locking connector, and a pressure-
screw terminal strip. The loudspeaker is intended to be connected directly to the amplifier.
If installed outdoors, the insulation of the installer-provided cabling should be resistant
to water, the effects of temperature, and the effects of ultraviolet radiation from the sun.
We recommend the use of a SJOW or SJOOW rated cable for most applications. To make
the connection from the loudspeaker to the wiring junction box when less than 3m (10')
in length. These are recommended insulations: UV-stabilized polyethylene, neoprene,
Teflon™, Silicon™, and Hypalon™. The following insulations are not recommended
because of potentially shorter life expectancy in outdoor environments: rubber, PVC
(polyvinyl chloride), polypropylene, polyurethane, and nylon. UV-stabilized polypropylene
may be acceptable.
Using the recommended cable with the included gland nut and the weather cover will
form a good weather-tight seal.
Examples of recommended cable include:
Grainger #1W312 (www.grainger.com)
McMaster-Carr #7422K61
(www.mcmaster.com)
__Wire the loudspeaker. We recommend
using spade or ring terminals with barrel-
type crimp connectors that are crimped
with a forged crimp tool (such as Klein
1005) or a ratcheting tool (such as Klein
T1720), as this method, when properly
executed, results in a gas-tight connection
that is quick and easy to accomplish. The
maximum width of the ring or spade lug
should be 0.375" (9.5mm), or less. The
terminal screws are #8 (M4). The maximum
wire size that can be accommodated for
bare wire connections is 10 AWG (5.26 mm
Important Note: If the NL4 connection is
used then the weatherproof cover cannot
be attached. Direct connection to the
terminal strips is the preferred connection
method for all permanent or outdoor
applications.

Note: Wire insulation colors may vary depending upon region or manufacturer. Be
consistent with conductor color use throughout the system.
IMPORTANT: The gland nut, weather cover and all of the attachment screws
must be used in outdoor and indoor harsh environment applications. Without
these, the loudspeaker will not have the stated weather-resistant rating and may
negate the warranty.
IMPORTANT: All electrical installation connections for loudspeaker lines are
subject to all applicable governmental building and fire codes. The selection of
appropriate electrical hardware to interface with the R SERIES loudspeaker lies
solely with the installation professional. Community recommends that an appropriately
licensed engineer, electrician, or other qualified professional identify and select the
appropriate conduit, fittings, wire, etc. for the installation.
DANGER: The output power capabilities of audio amplifiers present a danger to
installers especially in 70-volt and 100-volt distributed systems. To minimize the
risk of electric shock from loudspeaker connecting cables, confirm that the power
amplifiers are turned "off" before connecting loudspeaker cable(s) to the loudspeaker or
amplifier. Always follow local electrical codes and proper electrical safety procedures.
