GENERAL SAFETY AND
ASSEMBLY INSTRUCTIONS
MOUNTING ACCESSORIES for overhead installations (e.g. wall, ceiling and truss mounts)
1. General safety instructions
These mounting accessories may only be mounted and used:
- by qualified personnel familiar with the relevant regulations,
- in accordance with local and state regulations and the regulations for occupational insurance schemes
- as described in the assembly instructions (=installation and operating instructions),
- after a fault-free functional and visual inspection (completeness, operational safety; special attention must be paid to deformations, notches, cracks,
-
wear, damage to threads; corrosion and legibility of markings),
- without changing or processing the components,
- indoors (not in damp rooms).
2. General installation instructions
- The installation should be carried out by qualified personnel.
- Depending on the nature of the walls/ceilings and the type of load, fasteners of suitable design and sufficient dimensions must be used.
- In particular take into account the reduced load-bearing capacity of wall and ceiling coverings, facing plywood and insulation panelling.
- The specified tightening torques must be observed for all screw connections. If nothing is specified, the maximum tightening torques for the respective
-
screw connection apply.
3. Safety measures
Box systems must be secured against falling down in the area of stages or studios. A distinction is made between two types of protection:
1. Mobile installation (e.g. flying speakers, installation using C-hooks on trusses, manually detachable fastening elements) requires a second,
1.
independently acting safety element on the unit.
2. Stationary mounting allows the second securing element to be dispensed with if the fastening is sufficiently dimensioned and can only be detached
2.
with tools plus being protected against self-loosening.
2.
Nevertheless, we recommend using a second securing element.
4. Safety factors
Fasteners of loudspeaker boxes are safety-relevant parts that can endanger life and health of people in case of failure. Depending on the country in
which the article is used, the country-specific standards and guidelines for the sector "loudspeakers" must be observed respectively followed.
5. Inspection and maintenance
Overhead mounting is highly security relevant and requires an appropriate awareness of the potential danger. A safety inspection of the mounting
accessories is essential. If damage and/or malfunctions are found on accessories, the product must not be used again until it has been completely
overhauled.
- First of all, a visual and functional check must be carried out before initial operation, paying particular attention to deformations, cracks, wear,
-
corrosion, fault-free functioning and the legibility of markings.
- A regular inspection of fastening and accessory parts is recommended and also mandatory in many countries. We recommend an annual visual
-
inspection by qualified personnel and additionally a detailed inspection by an official expert every four years.
- We urgently recommend keeping an inspection logbook for the recurring tests where all accessories are entered together with their data and where
-
they can be viewed at any time for possible inspections.
