LEOPARD OPERATING INSTRUCTIONS
14
CAUTION: For 230 V AC, 3-phase Wye
systems, never connect two lines to the AC
input of LEOPARD, as the resulting voltage would
exceed the upper voltage limit (275 V AC) and will
damage the loudspeaker.
AC CONNECTORS
The LEOPARD user panel includes two powerCON 20
connectors (Figure 9), one for AC Input (blue) and one for AC
Loop Output (gray).
AC Input (Blue)
The blue AC Input connector supplies power to LEOPARD.
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 you replace the included AC power cable,
make sure to use a cable with the appropriate power plug (on
the other end) for the area in which you will operate the
loudspeaker. LEOPARD 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 additional
loudspeakers connected to the loudspeaker’s gray Loop
Output connector.
CAUTION: When looping AC power for
loudspeakers, 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 loudspeaker (Table 1).
AC Loop Output (Gray)
The gray AC Loop Output connector allows multiple
LEOPARDs to be looped and powered from a single power
source. The 3-conductor powerCON 20 is rated at 20 A and
uses a locking connector that prevents accidental
disconnections. For applications that require multiple
LEOPARDs, 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 LEOPARD loudspeaker
(Table 1).
NOTE: Current draw for LEOPARD is dynamic
and fluctuates as operating levels change. The
indicated number of loudspeakers that can be looped
assumes that operating levels are normal and not
such that loudspeakers are constantly limiting.
LEOPARD ships with a gray powerCON 20 cable mount
connector, rated at 20 A, for assembling AC looping cables.
Assembled AC looping cables are also available from Meyer
Sound.
CAUTION: When looping AC power for
loudspeakers, 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 loudspeaker (Table 1).
