3. Safety Instructions
Warning
The speaker is solely for professional use in the manner described here.
To prevent damage to persons and property, you must set up the speaker in compliance with
the specifications of applicable national standards.
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
The technicians responsible for assembling are responsible for the safe setup and use of the
speaker and guarantee this.
For mobile and fixed installations, use only assembly equipment from KLING & FREITAG.
If not otherwise stated in this manual, only original KLING & FREITAG parts may be used. The
use of other parts - in particular parts by other manufacturers - is not permitted.
As a basic principle, you must visually inspect all safety-relevant components of the speaker
and the accessory before every use. For fixed installations, you must inspect the speaker for
signs of wear at regular intervals. If there are signs of wear, cracks, or deformation, etc. then
you must replace the parts immediately.
Caution
When laying out the connecting cables, make sure that nobody can trip.
At least 2 people are necessary to carry the speaker.
Preventing hearing damage
Avoid beeing too close to operating speakers. Even loudness levels of approx. 90 dB - that
you subjectively judge as being low - can lead to hearing damage.
3.1 Notes for Mounting the Speakers
Warning
Mount the speakers securely. To avoid injury or damage, always be sure to mount the
speakers securely so that they do not fall.
Please note that speakers can move as a result of vibrations. To prevent them from falling
from their mounted position, they must be secured properly.
When laying out the connecting cables, make sure that nobody can trip.
3.2 Instructions for Speaker Stacking
Warning
Falling speakers pose the threat of fatal injuries to people near them!
Be sure to follow the relevant national specifications, norms, and safety regulations.
Always make sure that a sufficient safety level is still given, even when outside forces have
an additional impact on the stacked speakers. Before setup, carefully ascertain if there are
any possible outside forces that could result in the array falling over. (Slant of the ground /
the bearing capacity of the ground / wind / person or vehicle impact, etc.). A technical expert
who is responsible for the setup must evaluate and determine necessary measures (including
calculating the statics). If necessary, obtain expert proof of stability.
Stacked systems may not fall over even if they are inclined by 15° in each direction. If this
requirement is not fulfilled, then it is necessary to take steps to achieve compliance. Possible
measures include strapping it to an appropriate base structure or fastening it using safety
straps. A planned tilt of the loudspeakers ist not permissible. In calculations, the tilted setup
serves the purpose of levelling out unevenness.
With the set-up systems for which you cannot verify the structural safety without safeguards,
you must secure them to prevent sliding or tipping in order to provide proof of this safety. To
secure the system from tipping over, use water tanks or floor bolts. Other possible measures
include strapping it to a suitable substructure or tying it using safety straps.
