Instructions

Inspect the system before any deployment.

Perform safety related checks and inspections before any deployment.

Perform preventive maintenance at least once a year.

Refer to the preventive maintenance section for a list of actions and their periodicity.
Insufcient upkeep of the product can void the warranty.

If any safety issue is detected during inspection, do not use the product before performing

corrective maintenance.

Check for issues. A rigging system part or fastener is missing or loose. A rigging system part exhibits: bends,

breaks, broken parts, corrosion, cracks, cracks in welded joints, deformation, denting, wear, holes. A safety cue

or label is missing.

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.

Beware of sound levels.

Do not stay within close proximity of loudspeakers in operation.
Loudspeaker systems are capable of producing very high sound pressure levels (SPL) which can instantaneously

lead to permanent hearing damage to performers, production crew and audience members. Hearing damage

can also occur at moderate level with prolonged exposure to sound.
Check the applicable laws and regulations relating to maximum sound levels and exposure times.

Work with qualied personnel for rigging the system

Installation should only be carried out by qualied 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 congurations and the recommended safety precautions.

For safety issue, respect the maximum congurations outlined in this manual. To check the conformity of

any conguration 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 conguration.

Before installing/raising the product, check each individual element to make sure that it is securely fastened to the

adjacent element. Always verify that no one is standing underneath the product when it is being installed/raised.

Never leave the product unattended during the installation process.
As a general rule, L-Acoustics recommends the use of secondary safety 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.
