Safety
Instructions
Never incorporate equipment or accessories not approved by L-Acoustics.
Read all the related PRODUCT INFORMATION documents shipped with the products before
exploiting the system.
Do not store the product on an unstable cart, stand, tripod, bracket, or table.
Respect the Working Load Limit (WLL) of third party equipment.
L-Acoustics is not responsible for any rigging equipment and accessories provided by third party manufacturers.
Verify that the Working Load Limit (WLL) of the suspension points, chain hoists and all additional hardware
rigging accessories is respected.
Respect the maximum configurations and the recommended safety precautions.
For safety issue, respect the maximum configurations outlined in this manual. To check the conformity of
any configuration in regards with the safety precautions recommended by L-Acoustics, model the system in
Soundvision and refer to the warnings in Mechanical Data section.
Be cautious when flying a loudspeaker configuration.
Always verify that no one is standing underneath the loudspeaker array when it is being raised. As the array
is being raised, check each individual element to make sure that it is securely fastened to the adjacent element.
Never leave the array unattended during the installation process.
As a general rule, L-Acoustics recommends the use of safety slings at all times.
Be cautious when ground-stacking a loudspeaker array.
Do not stack the loudspeaker array on unstable ground or surface. If the array is stacked on a structure, platform,
or stage, always check that the latter can support the total weight of the array.
As a general rule, L-Acoustics recommends the use of safety straps at all times.
Take into account the wind effects on dynamic load.
When a loudspeaker assembly is deployed in an open air environment, wind can produce dynamic stress to the
rigging components and suspension points.
If the wind force exceeds 6 bft (Beaufort scale), lower down and/or secure the loudspeaker array.
Read the USER MANUAL before operating the system.
Use the loudspeaker system components described in the user manual and follow the operating instructions.
Do not expose the product to extreme conditions.
Do not expose the product to rain or sea spray.
Do not expose the product to moisture (mist, steam, humidity, condensation…) or excessive heat (direct sun,
radiator…) for a long period of time.

Mechanical safety
X8 rigging manual (EN) version 1.0 8
Mechanical safety
Maximum configurations
The X8 rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines
of BGV-CI.
2006/42/EC: Machinery Directive specifies a safety factor of 4:1 against the rupture. The limits specified in the tables
below are given with a safety factor of
—5:1 or higher for flown deployments,
—1.8:1 or higher for ground-stacked deployments.
Refer to Soundvision for the safety factor of a specific deployment.
The safe limit gives the maximum number of elements for which the safety factor is always compliant with the
2006/42/EC: Machinery Directive, regardless of the other deployment parameters (site angles, inter-enclosure angles,
etc.)
The maximum limit gives the maximum number of elements for which the safety factor can be compliant with the
2006/42/EC: Machinery Directive, when the other deployment parameters provide the best mechanical conditions.

Mechanical safety of the rigging system
Before any installation, always model the system in Soundvision and check the Mechanical Data section for
any stress warning or stability warning.
Mechanical safety
9 X8 rigging manual (EN) version 1.0
Assessing mechanical safety
In order to assess the actual safety of any array configuration before implementation, refer to the following warnings:
Rated working load limit (WLL) is not enough
The rated WLL is an indication of the element resistance to tensile stress. For complex mechanical systems such as
loudspeaker arrays, WLLs cannot be used per se to determine the maximum number of enclosures within an array
or to assess the safety of a specific array configuration
Mechanical modeling with Soundvision
The working load applied to each linking point, along with the corresponding safety factor, will depend on
numerous variables linked to the composition of the array (type and number of enclosures, splay angles) and the
implementation of the flying or stacking structure (number and location of flying points, site angle). This cannot be
determined without the complex mechanical modeling and calculation offered by Soundvision.
Assessing the safety with Soundvision
The overall safety factor of a specific mechanical configuration always corresponds to the lowest safety factor
among all the linking points. Always model the system configuration with the Soundvision software and check the
Mechanical Data section to identify the weakest link and its corresponding working load. By default, a stress
warning will appear when the mechanical safety goes beyond the recommended safety level.
Safety of ground-stacked arrays in Soundvision
For ground-stacked arrays, a distinct stability warning is implemented in Soundvision. It indicates a tipping hazard
when the array is not secured to the ground, stage or platform. It is user responsibility to secure the array and to
ignore the warning.
Additionnal safety for flown arrays
When flying an array, use the M8 DIN580 threaded insert to implement a secondary safety.
Considerations must be given to unusual conditions
Soundvision calculations are based on usual environmental conditions. A higher safety factor is recommended
with factors such as extreme high or low temperatures, strong wind, prolonged exposition to salt water, etc.
Always consult a rigging specialist to adopt safety practices adapted to such a situation.
