CHAPTER 2: POWER REQUIREMENTS
CAL loudspeakers combine advanced loudspeaker technol-
ogy with equally advanced power capabilities. Understand-
ing voltage and current requirements, as well as electrical
safety issues, is critical to CAL’s safe operation.
AC INPUT CONNECTOR
The CAL user panel includes a 3-pole, PowerCon AC Input
connector. The AC Input connector supplies power to the
CAL loudspeaker. The connector is rated at 20 amps and
uses a PowerCon3 AC mains locking connector that pre-
vents accidental disconnections. A 10-foot AC power cable,
rated at 15 amps, is included with each CAL loudspeaker.
CAL loudspeakers require a grounded outlet. To operate
safely and effectively, it is extremely important that the entire
system be properly grounded.
If you replace the included AC power cable, make sure to
use a cable that is wired correctly and equipped with the
appropriate power plug (on the other end) for the area in
which you will operate the unit.
WIRING FOR AC CONNECTIONS
CAL loudspeakers require a grounded outlet. To operate
safely and effectively, it is extremely important that the entire
system be properly grounded.
When wiring international or special-purpose AC power
cables and connectors, use the following wiring scheme:
■ Connect the blue wire to the black terminal, or the termi-
nal marked with an N.
■ Connect the brown wire to the red terminal, or the termi-
nal marked with an L.
■ Connect the yellow and green wire to the green (or green
and yellow) terminal, or the terminal marked with an E.
CAUTION: When creating AC power cables, it
is important to preserve AC line polarity and
connect the earth ground on both ends of the cable.
CAL requires a grounded connection. Always use a
grounded outlet and plug. It is extremely important
that the system be properly grounded in order to
operate safely and properly. Do not ground-lift the AC
cable.
