1. Safety

1.1. Intended use

The Vi rigging components must only be used in conjunction with
d&b Vi loudspeakers as described in this manual.

1.2. General safety

Installation and setup should only be carried out by qualified and
authorized personnel observing the valid national Rules for the
Prevention of Accidents (RPA).

It is the responsibility of the person installing the assembly to ensure
that the suspension/fixing points are suitable for the intended use.

Always carry out a visual and functional inspection of the items
before use. In case there is any doubt as to the proper functioning
and safety of the items, these must be withdrawn from use
immediately.

Please also refer to Þ Chapter 6. "Care and maintenance /
Disposal" on page 35.

1.3. Load capacity/System safety

Z5387.000 Vi Mounting frame top

The Vi Mounting frame top is designed to suspend smaller arrays
of Vi-TOP or Vi-SUB cabinets with a total system weight of up to
136 kg (300 lb) - SWL, which corresponds to a total weight of up
to 4 x Vi-TOP cabinets.

For any other array configuration which exceeds the maximum
permissible system weight for the Vi Mounting frame top, the
Z5380 V Flying frame must be used.

Note: A detailed description of the Z5380 V Flying frame
including the relevant assembly instructions is given in the V­Series Rigging manual, which is supplied with the V Flying
frame.

Z5387.001 Vi Mounting frame bottom

The Z5387.001 Vi Mounting frame bottom is designed as a
pullback device to fix and/or pull back an array with either the
Z5387.000 Vi Mounting frame top or the Z5380 V Flying frame
attached at the top of the array.

Alternatively, the frame can be used as an adapter frame to be
mounted underneath SUB cabinets in mixed array configurations
with the Z5380 V Flying frame on top of the array. In this case, the
frame can support a total system weight of up to 136 kg (300 lb) ­SWL, which corresponds to a total weight of up to 4 x Vi-TOP
cabinets.

For any other array configuration which exceeds the maximum
permissible system weight for the Vi Mounting frame bottom, the
Z5380 V Flying frame must be used.

Note: A detailed description of the Z5380 V Flying frame
including the relevant assembly instructions is given in the V­Series Rigging manual, which is supplied with the V Flying
frame.

1.3.1. Wind loads

WARNING!
Potential risk of personal injury and material

damage!

When setting up fixed outdoor installations, unpredictable wind
loads must be taken into account.

The dedicated fixing points for the array assemblies described in
this manual are detailed in Þ Chapter 5. "Hoisting and aiming the
array" on page 33.

1.4. d&b ArrayCalc calculator software / TI 385

For both acoustic and safety reasons d&b line arrays must be
designed using the d&b ArrayCalc simulation tool. It is available as
a native stand-alone application for both Microsoft Windows (XP
or higher) and Mac OS X (10.4.10 or higher) operating systems
and can be downloaded at www.dbaudio.com.

The use of ArrayCalc is described in "TI 385 d&b Line array
design, ArrayCalc". This TI includes typical array configurations
within the permitted load limits. Carefully read this TI to become
familiar with the operation and behavior of ArrayCalc and in
particular with the mechanical load conditions and limitations.

d&b ArrayCalc

The TI can be downloaded from the d&b website at

www.dbaudio.com.

1.5. Secondary safety

WARNING!
Potential risk of personal injury and/or

damage to material!

The secondary safety suspension must be independent of the
primary suspension points and capable of carrying the total system
weight.

The additional safety device must be mounted in a way that the
array is caught by the safety device without any drop and swing in
the event that the primary suspension fails.

d&b Vi Rigging manual (1.2 EN) 5

1.6. Operational safety

The assembly should always be carried out by two persons.

During assembly pay attention to the possible risk of crushing.
Wear suitable protective clothing.

Observe all instructions given on the respective instruction labels of
the rigging components and loudspeaker cabinets.

When chain hoists are in operation ensure that there is nobody
directly underneath or in the vicinity of the load.

Do not under any circumstances climb on the array.

2. Rigging concept and components

2.1. Mounting and flying frames

The d&b Vi loudspeakers are supplemented by two mounting
frames, the Z5387.xxx Vi Mounting frames, one for the top and
one for the bottom of an array.

These frames allows the setup of the following array
configurations:

NOTICE!
Construction notes

Each side of the tie bar at the front end of the frame is equipped
with a Front link. Both Front links are undetachably attached to the
tie bar using a fixing bolt. Directly above each of these fixing bolts
there is a Locking pin that serves to additionally stabilize the Front
link in its recess. For safety reasons, this Locking pin must always
be inserted and locked.

In addition, there is a second Locking pin on each side of the tie
bar which is used to connect the frame with a cabinet.

2.2. Ring cotters

In connection with the Vi rigging system, ring cotters are used for
the following items to prevent the respective item from slackening
and/or loosening:

– Fixing bolt of the TOP and SUB cabinet's Rear links.
– Fixing bolt of the frame's Rear links and cable picks.

Function of the ring cotter

By default, the ring cotters are "locked" to prevent them from
loosening.

For modification reasons such as altering the position of the frame's
Splay link or exchanging a shackle, it may be necessary to
temporarily remove the cotter and reattach it afterwards.

For this purpose proceed as follows:

1. Unlock

Unlock the ring cotter by pushing up the front wire loop over
the straight wire shaft.

2. Release and remove

Push down the rear wire loop until the ring cotter snaps over
the edge of the bolt and remove the ring cotter.

3. Refit and lock

Refit the ring cotter by pushing the straight wire shaft through
the hole and pressing the front wire loop underneath the
straight wire shaft.
