Warning The following arrays (maximum configurations) fulfil the stipulations of the BGV C1 with
their given design:
Maximum number of flown speakers:
• SEQUENZA 10 N and SEQUENZA 10 W:
Arrays of up to 13 speakers and a flying frame inclination less than +/- 4°.
• SEQUENZA 10 B:
Arrays of up to 12 speakers.
• SEQUENZA 10 N/W combined with SEQUENZA 10 B:
For combined arrays consisting of SEQUENZA 10 N/W and SEQUENZA 10 B, a special
verification with the CON:SEQUENZA simulation software is mandatory.
If these angles or the number of speakers is exceeded, it is mandatory that you separately
verify the array with the CON:SEQUENZA simulation software. CON:SEQUENZA
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.
Follow the relevant specified safety factors. The safety factors (SF) are stated on the back
of the speakers and they comply with the BGV C1. Be sure to follow the relevant national
specifications, norms, and safety regulations.
Note that every suspension point as well as the supporting structure of the building (i.e.
ceiling points, cross beams and stage or PA tower, etc.) must be capable of carrying the total
load of the system (including cabling and additional fittings).
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. If in doubt, have it checked by local authorities.
Also, follow the operating and safety instructions for the product from which you will
suspend the flying frame (i.e. truss). If there is no information regarding the safe use and the
working load limit, you may not fly the flying frame from it.
Every chain and every motor must be capable of carrying the total load of the array on its
own, even with two-strand rigging. Check to make sure that the chains of the hoist motors
are hanging straight down and are not twisted and that the hoist motors are in the intended
positions.
When operating with chain hoists that do not comply with the BGV C1 or the D8+, no one
may be present in the danger zone underneath or near the speaker array.
Secure the array from falling with a second independent safety fitting if no BGV C1 or D8+
motor is used.
Never use signal cables or power cords for suspending, aligning or securing the systems.
When laying out the connecting cables, make sure that nobody can trip.
Make sure you have enough free working space on site to assemble and suspend the array.
The array can swing out while being lifted!
Only personnel directly involved with assembly or disassembly may be in the working area.
Every time before the responsible technician raises or lowers the flying frame, he must
unmistakably signal this to all people. All persons must then move outside of the pivoting
and lifting range.
The flying frame may not be used to lift and secure people or objects other than the above-
mentioned speaker systems.
The array may not be used as a climbing aid.
The safe use of the flying frame and the speakers also depends on the various factors present
at the area of use. Weather conditions such as wind or rain, for example, can compromise
the safety of the flying frame and speakers. Always consider and evaluate these factors. (See
chapter 'Wind Loading' on page 14.)
