Rigging Instructions - Outline SCALA 90 User Manual

Scala 90 can be configured in different ways to
achieve different coverage targets.
In order to create both vertical and horizontal
arrays, external fixed hardware accessories are
required. In both cases, the loudspeakers must
always be connected on both sides with the dedicated
accessory plates provided by Outline (the transparent
blue ones in the image below) or with external
hardware, structure. The external hardware must
be approved by a licensed professional engineer.
For the vertical array it is possible to use either
a load-bearing structure or lifting devices such as
eyebolts. The bearing structure must be designed
according to the local laws and local safety factors,
considering the total load of the system, the dynamic
factors inducted by vibrations, winds and mounting
procedures (responsibility of the installer). If eyebolts
are used, with Outline plates, please check the load
capacity before the installation (The maximum
capacity, indicated in kg, on the eyebolts refers to
the straight throw; the capacity for the orthogonal
pull at 90° is indicated on the package label).

For the horizontal array lifting devices must be
used, certified for the weight to hang (the eyebolts
shown in the following figure are just an example). At
least one lifting devices for every two loudspeakers
shall be guaranteed with alternate speakers (as
shown in the figure below) in order to distribute the
load, with relative chain (in this case it is possible
to make a complete circle of loudspeakers and
therefore have a coverage of 360°). Please note that
is very important to consider also the inclination of
the array.
A fall protection system must be created with
suitable devices such as rope or chains, the M10
points can be used for this purpose.
Safety devices must be used to guarantee the
tightness of the assemblies over time, for example
washers with folding tabs. In addition, tie rods must
be provided to counteract the wind.
The cables and chains used for the installation
shall be connected to the supporting structure on
the vertical axis respect to the fixing points on the
cabinet (or with an inclination of a few degrees) and
they must all be tense to avoid overloading a single
point.
The maximum number of cabinets per array is
strictly related to the hanging method used.
