Safety Instructions
3.1
Mounting the Speakers / Wall and Ceiling Installation
Warning
Suspended loads pose a safety risk.
Only qualified technicians are permitted to perform the installation steps. Be sure to use
personal protective equipment at all times.
The technicians installing the speaker on site are responsible for and guarantee safe setup
and use.
Never use signal cables or power cords for suspending, aligning, or securing the systems.
Before installing, check the stability, strength, and materials of walls, ceilings, and boarding.
For example, use suitable rawlplugs for wall panels and make sure the strength is sufficient.
Note that the suspension points on the hall ceiling (i.e. shackles, attachment points, or chain
hoists) must comply with the DGUV regulations 17 or similar locally applicable accident-
control standards. The maximum load must have been certified by an authorized expert.
Be sure to tighten all bolts and screws to the specified torque.
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).
Make sure all fittings used are suitable for the task at hand and meet all relevant safety
requirements.
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.
Be sure to always visually inspect all safety-related speaker and accessory components
before use. If there are signs of wear, cracks, or deformation, etc., replace the affected parts
immediately. Visual inspection also includes checking all screwed connections of supporting
components.
The information described here does not relieve the user of the duty to follow the given
safety requirements and legal regulations.
3.2
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.
Run the cables in a way that nobody can trip over them.
