HARDWARE SETUP PROCEDURE
Before proceeding with assembly of GEO S12 EN54 arrays, please ensure that the components are present and undamaged.
A component list is appended to this manual. In the event of any shortage, please contact your supplier.
For maximum efficiency the GEO S12 EN54 rigging system requires three experienced persons for set-up: typically, one motor
hoist operator, and one operator per side of the array. Good synchronisation and crosscheck between the operators are key
elements for a reliable and safe set-up.
7.1 Safety first
GEO S12 EN54 Rigging System structural computations and related documents are available in NS-1 or at NEXO (info@nexo.fr)
upon request.
We include this section to remind you of safe practice when flying the GEO S12 EN54 system. Please read it carefully. However,
user must always apply his or her knowledge, experience and common sense. If in any doubt, seek advice from your supplier
or NEXO agent.
This manual offers guidance only for GEO S12 EN54 loudspeaker systems. References in this manual to other rigging
equipment such as motor hoists, steels, shackles etc. are made to clarify the description of rigging procedures. The user must
ensure that operators are properly trained by other agencies in the use of these items.
The GEO S12 EN54 Rigging System has been optimised for the deployment of curved vertical or horizontal tangent arrays of
GEO S12 EN54 loudspeakers. Angle adjustment between cabinets has been limited to specific settings to ensure correct
acoustic coupling.
The GEO S12 EN54 Rigging System is a professional precision tool set and should be handled with extreme care. Only persons
who are fully conversant with the operation of the GEO S12 EN54 Rigging System and provided with suitable safety equipment
should deploy GEO Arrays. Misuse of the GEO S12 EN54 Rigging System could lead to dangerous consequences.
Used and maintained correctly, the GEO S12 EN54 Rigging System will give many years of reliable service in portable systems.
Please take the time to read and understand this manual. Always use NS-1 to determine the optimum angle settings for a
particular venue, hang point and curved vertical GEO S12 EN54. Applied forces and moments are strongly cabinet quantity and
angle configuration dependent. Cluster configuration must be implemented and validated in NS-1 prior to installation.
7.1.1 Flown systems safety
Always inspect all the rigging components and cabinets for damage before assembly. Pay special attention to the lifting points,
and safety clips. If you suspect that any of the components are damaged or defective, DO NOT USE THE AFFECTED PARTS.
Contact your supplier for replacements.
Read this manual carefully. Also, be familiar with the manuals and safe working procedures for any ancillary equipment that will
be used with the GEO S12 EN54 Rigging System.
Applied forces and moments are strongly cabinet quantity and angle configuration dependent. Cluster configuration must be
implemented and validated in NS-1 prior to installation.
Ensure that all local and National regulations regarding the safety and operation of flying equipment are understood and adhered
to. Information on these regulations can usually be obtained from Local Government Offices.
When deploying a GEO S12 EN54 system always wear protective headwear, footwear and eye protection.
Do not allow inexperienced persons to handle a GEO S12 EN54 system. Installation personnel should be trained in loudspeaker
flying techniques and should be fully conversant with this manual.
Ensure that motor hoists, hoist control systems and ancillary rigging components are currently certified as safe and that they
pass a visual inspection prior to use.
Ensure that public and personnel are not allowed to pass beneath the system during the installation process. The work area
should be isolated from public access.
Never leave the system unattended during the installation process.
Do not place any object, no matter how small or light, on top of the system during the installation procedure. The object may fall
when the system is flown and is likely to cause injury.
Secondary safety steels must be installed once the system has been flown to the operating height. Secondary steels must be
fitted irrespective of requirements of the local safety standards applicable to the territory.
Ensure that the system is secure and prevented from pivoting around the motor hoist.
Avoid any form of excessive dynamic loading to the assembly (structural computations on GEO S12 EN54 Rigging System are
based on a 1/1.2 factor for hoist or motor acceleration).
NEVER attach any item to the GEO S12 EN54 system other than the GEO S12 EN54 accessories.
When flying outdoor systems ensure that the system is not exposed to excessive wind or snow loads and is protected from
rainfall.
