ELECTRICAL SAFETY GUIDELINES
Make sure to observe the following important electrical and
safety guidelines.
•The powerCON 32 connector should not be engaged or
disengaged when under load or energized. Either de-
energize or disconnect the other end of the cable.
•LYON requires a grounded outlet. Always use a
grounded outlet and plug.
•Do not use a ground-lifting adapter or cut the AC cable
ground pin.
•Make sure the AC power cable for the loudspeaker has the
appropriate power plug (on the other end) for the area in
which you will operate the loudspeaker.
•Do not operate the loudspeaker if the power cable is
frayed or broken.
•Keep all liquids away from LYON loudspeakers to avoid
hazards from electrical shock.
•Use the cable rings (see “Cable Rings” on page 16) on
the rear of the LYON cabinet to reduce strain on the AC
power cable (and audio cables). Do not use the cable
rings for any other purpose.
