Safety
The ELX200 loudspeakers and rigging accessories in this manual have a minimum structural
safety factor of 8:1 when used as intended. The safety factor is defined as the ratio of the
ultimate-break strength divided by the working-load limit. The ultimate-break strength
represents the force at which a part will structurally fail. The working-load limit is the
maximum load that the user shall apply. The safety factor provides a margin of safety above
the working-load limit to accommodate normal dynamic loading and normal wear.
When ELX200 loudspeaker systems are suspended using the ELX200 rigging accessories as
illustrated in this manual, the resulting loads will be within the working-load limits of both the
loudspeaker systems and the rigging accessories, and a safety factor of at least 8:1 will be
maintained. The use of rigging configurations other than recommended by Electro-Voice in this
manual for either the ELX200 loudspeaker systems or ELX200 rigging accessories are at the
risk of the user.

Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.
Prior to use, inspect the suspension points and associated hardware for any cracks,
deformations, broken welds, corrosion, missing or damaged components which could reduce
the suspension points strength. Replace any damaged hardware. Never exceed the limitations
or maximum recommended load intended for the suspension points. As an added safety
measure, it is suggested the user install an extra suspension point back to the building
structural supports. This redundant safety point should have as little slack as possible (less
than one inch is preferable). Prior to each use, inspect the loudspeaker enclosures for any
cracks, deformations, missing or damaged components, which could reduce enclosure
strength. Replace any loudspeaker systems that are damaged or missing hardware.

Warning!
Eyebolts must be fully seated and oriented in the plane of pull. Always use washers under the
eyebolt to distribute the load on the enclosure.
