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
CAL receives AC power from its 3-pole powerCON 20 lock-
ing connector. Located on the unit's rear panel, the connec-
tor is rated at 20 A and provides locking connections to
avoid accidental disconnections. A 10-foot AC power cable,
rated at 15 amps, is included with each CAL loudspeaker.
CAL AC Input Connector
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.
Blue = neutral
Brown = hot
Yellow/green =
earth ground
(chassis)
AC Cable Wiring Scheme
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.
