LYON OPERATING INSTRUCTIONS
12
CAUTION: For 230 V AC, 3-phase Wye
systems, never connect two lines to the AC
input of LYON, as the resulting voltage would exceed
the upper voltage limit (275 V AC) and will damage
the loudspeaker.
AC INPUT
The LYON user panel includes an AC Input connector that
supplies power to the loudspeaker. The 3-conductor
PowerCON 32 (Figure6) is rated at 32 A and uses a locking
connector that prevents accidental disconnections.
LYON ships with a black powerCON 32 cable mount
connector, rated at 32 A, for assembling AC power cables.
Make sure to use an AC power cable that is wired correctly
(see “Wiring AC Power Cables” on page 12) and equipped
with the appropriate power plug (on the other end) for the area
in which you will operate the unit.
LYON requires a grounded outlet. To operate safely and
effectively, it is extremely important that the entire system be
properly grounded.
WIRING AC POWER CABLES
LYON 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 (see “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. LYON 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.
