4. Safety Instructions
Warning
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
Only qualified technicians are permitted to perform the installation steps. Be sure to use
personal protective equipment at all times.
The technicians responsible for installing the system on site are responsible for and
guarantee safe setup and use.
To prevent injury and damage, be sure to securely place or suspend the speaker array as
specified in the DGUV regulations 17 and 18 or similar locally applicable accident-control
standards.
Unless otherwise stated, use only KLING & FREITAG original parts for mounting the speakers.
Never use other parts (in particular, parts not made by KLING & FREITAG).
In mobile and stationary installations, always use installation parts supplied by KLING &
FREITAG.
Be sure to always visually inspect all array components before use. In fixed installations,
regularly check all array components for signs of wear. Visual inspection includes checking all
speaker-system and flying frame components, supporting components (e.g. trusses, ceiling
structures, etc.), and all screwed connections. During the inspection, check all flying-system
components carefully for deformation, cracks, bolt damage, and corrosion. Remember
checking the fixing pin and pin bolts for proper functioning. Also check slings and lifts (e.g.
shackles, chains, and steel ropes) carefully for wear and deformation. If there are signs of
wear, cracks, or deformation, etc., replace the affected parts immediately. See also the “Care
and Maintenance” chapter on page 37.
4.1 Safety Instructions for Flying Configurations
Warning
Loudspeakers falling down impose a deadly risk for people standing near-by!
Never use the array if you have any doubt regarding its safety and reliability!
Only qualified event technicians are permitted to suspend a VIDA L system.
Never suspend the speakers without the correct flying frame.
Maximum-load specifications refer to configurations including cabling and any fittings.
Use the simulation function provided by the VIDA App software to find out whether your
configuration loads the flying frame as allowable. The VIDA App software does not account
for the weight of extra cabling and fittings! Remember to take any such extra weight into
account—if necessary, reduce the number of speakers as required.
Ensure that all connections are secured against coming loose and that only authorized,
statically tested and correctly sized supports, mounting equipment, wire ropes and chains
are used. Follow the relevant specified safety factors. Be sure to follow the relevant national
specifications, norms, and safety regulations.
Note that every suspension point as well as the supporting structure of the building (i.e.
ceiling points, cross beams and stage or PA tower, etc.) must be capable of carrying the total
load of the system (including cabling and additional fittings).
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or
chain hoists) must comply with the DGUV regulations 17 and 18 or similar locally applicable
accident-control standards. The maximum load must have been certified by an authorized
expert. When in doubt, request a confirmation by local authorities.
Also follow the operating and safety instructions supplied with the product you intend to
suspend the flying frame from (e.g. a truss). Never mount the flying frame to a product if
there is no information on safe use and maximum load.
Even with two-fall suspension, each chain and motor must be capable of carrying the entire
array mass! Make sure that the motor chains hang down vertically and are not twisted, and
that the motors are located at the required positions.
