SAFETY INSTRUCTIONS
1. Read this manual
2. Heed all SAFETY INSTRUCTIONS as well as DANGER and O LIGATION warnings
3. Never incorporate equipment or accessories not approved by L-ACOUSTICS
®
4. Read all the related PRODUCT INFORMATION documents before exploiting the system
The product information document is included in the shipping carton of the related system component.
5. Work with qualified personnel for rigging the system
Installation should only be carried out by qualified personnel that are familiar with the rigging techniques and safety
recommendations outlined in this manual.
6. Ensure personnel health and safety
During installation and set-up personnel must wear protective headgear and footwear at all times. Under no
circumstances personnel is allowed to climb on a loudspeaker assembly.
7. Respect the Working Load Limit (WLL) of third party equipment
L- COUSTICS
®
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.
8. Respect the maximum configurations and the recommended safety level
For safety issue, respect the maximum configurations outlined in this manual. To check the conformity of any
configuration in regards with the safety level recommended by L- COUSTICS
®
, model the system in
SOUNDVISION and refer to the warnings in Mechanical Data section.
9. e cautious when flying a loudspeaker array
lways verify that no one is standing underneath the loudspeaker array when it is being raised. s 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. s a general rule, L- COUSTICS
®
recommends
the use of safety slings at all times.
10. e 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. s a general rule, L- COUSTICS
®
recommends the use of safety straps at all times.
11. 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.

Mechanical safety of the shackles
The bow shackles Ø12mm provided by L- COUSTICS
®
have a working load limit (WLL) of 1000 kg with a 6:1
safety factor. This rating is in accordance with BGV-C1 (2012) recommendations when implementing the
maximum configurations authorized by L- COUSTICS
®
.
Mechanical safety of the rigging system
Maximum configurations indicate the maximum number of enclosures which can be safely arrayed without the
need for SOUNDVISION modeling. For more enclosures, model the system in SOUNDVISION and check
the Mechanical Data section for any stress warning or stability warning.
2.2 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. lways 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 below 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 this warning.
Consideration must be given to unusual con
ditions
SOUNDVISION calculations are based upon usual environmental conditions. higher safety factor is
recommended with factors such as extreme high or low temperatures, strong wind, prolonged exposition to
salt water, etc. lways consult a rigging specialist to adopt safety practices adapted to such a situation.
