Instructions
Inspect the product before operation.
If any sign of defect or damage is detected, immediately withdraw the product from use for maintenance.
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.
Work with qualied personnel for rigging the system
Installation should only be carried out by qualied personnel that are familiar with the rigging techniques and
safety recommendations outlined in this manual.
Ensure personnel health and safety
During installation and set-up personnel must wear protective headgear and footwear at all times. Under no
circumstances is personnel allowed to climb on a loudspeaker assembly.
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 congurations and the recommended safety precautions.
For safety issue, respect the maximum congurations outlined in this manual. To check the conformity of
any conguration 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 ying a loudspeaker conguration.
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.
Risk of falling objects
Verify that no unattached items remain on the array.
Risk of tipping
Remove all rigging accessories before transporting an array.
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.
This system is intended for professional use.
Read the USER MANUAL before operating the system.
Use the loudspeaker system components described in the user manual and follow the operating instructions.

Mechanical safety
Mechanical safety
Flown congurations
The Syva rigging system complies with 2006/42/EC: Machinery Directive. It has been designed following the guidelines
of BGV-C1.
2006/42/EC: Machinery Directive species a safety factor of 4 against the rupture. The own deployments described in
this manual achieve a safety factor of 5.
Refer to Soundvision for the safety factor of a specic 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
Assessing mechanical safety
In order to assess the actual safety of any array conguration 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 specic array conguration.
Maximum pullback angle
If a pullback accessory is available, the pullback angle must not exceed a 90° negative site angle.
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 ying or stacking structure (number and location of ying 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 specic mechanical conguration always corresponds to the lowest safety factor
among all the linking points. Always model the system conguration 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 the user's responsibility to secure the array
and to ignore the warning.
Additional safety for own arrays
When ying an array, use available holes 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.
