230 V AC, 3-Phase Wye System (Single Line)
Line-Neutral-Earth/Ground
Figure 9 illustrates a basic 230 V AC, 3-phase Wye distribu-
tion system with the loudspeaker load distributed across all
three phases, with each loudspeaker connected to a single
line and common neutral and earth/ground lines. This sys-
tem delivers 230 V AC to each loudspeaker.

CAUTION: For 230 V AC, 3-phase Wye sys-
!
tems, never connect two lines to the AC input
of LINA, as the resulting voltage would exceed the
upper voltage limit (275 V AC) and will damage the
loudspeaker.

AC CONNECTORS

The LINA user panel includes two powerCON 20 connectors
(Figure 10), one for AC Input (blue) and one for AC Loop
Output (gray).
Figure 10: AC Input (Left) and AC Loop Output (Right) Connectors
AC Input (Blue)
The blue AC Input connector supplies power to LINA. The 3-
conductor powerCON 20 is rated at 20 A and uses a locking
connector that prevents accidental disconnections. A
10-foot AC power cable, rated at 15 A, is included with each
loudspeaker. If the included AC power cable is replaced,
make sure to use a cable with the appropriate power plug
(on the other end) for the region where the unit will be
operated. LINA requires a grounded outlet. To operate
safely and effectively, it is extremely important that the
entire system be properly grounded.

The AC Input connector also supplies power to any addi-
tional loudspeakers connected to the loudspeaker's gray
Loop Output connector.
CAUTION: When looping AC power for loud-
!
speakers, do not exceed the current capability
of the AC Input connector (20 A) or the included AC
power cable (15 A). Consider the total current draw for
all loudspeakers on the circuit, including the first loud-
speaker (Table 1).
AC Loop Output (Gray)
The gray AC Loop Output connector allows multiple LINAs
to be looped and powered from a single power source. The
3-conductor powerCON 20 is rated at 20 A and uses a lock-
ing connector that prevents accidental disconnections. For
applications that require multiple LINAs, connect the AC
Loop Output of the first loudspeaker to the AC Input of the
second loudspeaker, and so forth.
The maximum number of loudspeakers that can be looped
from the AC Loop Output connector is determined by the
voltage of the power source, the current draw of the looped
loudspeakers, the circuit breaker rating, and the rating of the
AC power cable connected to the first LINA loudspeaker
(Table 1).

NOTE: Current draw for LINA is dynamic and
fluctuates as operating levels change. The indi-
cated number of loudspeakers that can be looped
assumes that operating levels are normal and not
such that loudspeakers are constantly limiting.
LINA ships with a gray powerCON 20 cable mount connec-
tor, rated at 20 A, for assembling AC looping cables.
Assembled 1-meter AC looping cables (PN 28.115.032.03)
are also available from Meyer Sound.
