WIRING AC POWER CABLES
The 1100-LFC ships with a black powerCON 32 cable
mount connector (Figure 7), rated at 32 A, for assembling
AC power cables. The pins on the powerCON 32 cable
mount connector are labeled as follows:
• L (Line)
• N (Neutral)
• PE (Protective Earth or Ground)

How AC power cables are wired is determined by the type
of AC power distribution system used ("AC Power
Distribution" on page 11). When wiring AC power cables for
single-line systems, use one of the wiring schemes
described in Table 1 and illustrated in Figure 8:

CAUTION:
When wiring AC power cables and
distribution systems, it is important to preserve
AC line polarity and connect the earth ground on both
ends of the cable. The 1100-LFC requires a grounded
connection. Always use a grounded outlet and plug.
It is extremely important that the system be properly
grounded to operate safely and properly. Do not
ground-lift the AC cable.

1100-LFC VOLTAGE REQUIREMENTS
CAUTION:
ities, the 1100-LFC was engineered to operate
only at 230 V AC (208–235 V AC) to reduce current
draw. Make sure to use AC power cables with suffi-
cient gauge to operate with stable voltages during
PE
peaks and that the AC power source is capable of
providing enough power.
The 1100-LFC operates as intended when receiving AC
voltage within the following range:
• 165–264 V AC, 50–60 Hz
If the voltage drops below 165 V, the loudspeaker uses
stored power to continue operating temporarily; the
loudspeaker powers off if the voltage does not return to its
operating range.
If the voltage rises above 275 V, the power supply could
become damaged.
CAUTION:
forms as specified, without interruption, and
without damage to its power supply:
1. Its power source must operate within the required
voltage window (208–235 V AC).
2. Its AC cable length and gauge must be such that
peak voltage drops do not exceed 5 percent of the
supplied voltage.
NOTE:
When voltage fluctuates within the
loudspeaker's operating ranges, automatic tap
selection stabilizes the voltage. Tap selection is
instantaneous with no audible artifacts, allowing con-
tinuous operation.
1100-LFC CURRENT REQUIREMENTS
Current draw for loudspeakers is dynamic and fluctuates as
operating levels change. Because different cables and
circuit breakers heat up at varying rates, it is important to
