Flying Points with a standard M10 thread or with the quick connecting 'K&F Lifting Pin'. The

50°. The model GRAVIS 15 W has a coverage angle of 90° x 50°. Its elegant design suitable for

3. Safety Instructions

3.1 Mounting the Speakers / Wall and Ceiling Installation

Warning

Suspended loads are safety related.

The speakers may only be mounted by qualified event technicians or personnel which are

instructed by them, adequately. This also applies for wall and ceiling fixations.

The technicians responsible for assembling the speakers on site are responsible for the safe

setup and use of the speakers and guarantee the safe use of the mounting elements.

Never use signal cables or power cords for suspending, aligning or securing the systems.

Before carrying through ceiling and wall installations, it is essential to consider the load

capacity, the stability and type of the construction of walls, ceilings and panelling. If there is

wall panelling, for example, it is then necessary to examine the solidity of the wall and use

the appropriate wall plugs.

Note that the suspension points on the hall ceiling (i.e. shackles, suspension points, or chain

points) must comply with the accident prevention regulation BGV C1 (Event and Production

Sites for Stage Presentations) or comparable applicable national standards, and the total load

must be approved by an authorised expert.

Make sure to comply with the stipulated tightening torques.

If not otherwise stated in this manual, only original KLING & FREITAG parts may be used for

mounting the speakers. The use of other parts – in particular parts by other manufacturers –

is not permitted in this case.

Ensure that all installation connections comply with the applicable safety guidelines and that

the size and strength are sufficient.

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.

As a basic principle, you must visually inspect all safety-relevant components of the speaker

and the accessory before every use. If there are signs of wear, cracks, or deformation, then

you must replace the parts immediately. The visual inspection also includes checking the

screwed connections on supporting elements.

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.

When laying out the connecting cables, make sure that nobody can trip.

3.3 Preventing hearing damage

Caution

Avoid beeing too close to operating speakers. This equipment is capable of delivering sound

pressure levels in excess of 90 dB SPL, which may cause permanent hearing damage.
