The payload of the BBT24 bracket is designed of not more than six T24(N) loudspeaker. The
following additional components are required for this: CBT24 cradle bar for flying, BCT24 rig-
ging adapter and BLT24 Boxlink connecting cables on both sides of the T24(N) loudspeaker.
Do not exceed this payload.
WARNING
When moving (assembling, dismantling, maintaining) the BBT24 bracket with T24(N) loudspe-
aker, ensure sufficient space to prevent collisions with other objects.
WARNING
Do not squeeze or twist the electrical cables of the T24(N) loudspeaker during the installa-
tion of the BBT24 bracket! The respective national electrotechnical rules and regulations are
applicable.
CAUTION
Before mounting the BBT24 bracket check that e.g. trusses or ceilings are capable to carrying
the payload of the components.
WARNING
WARNING
WARNING
Make sure that no water pipes, electrical lines or any other lines are behind the intended place
of mounting.
Only use wall plugs and screws which are suitable for the intended mounting and structural
fabric. All screws must be set and tightened properly. Ensure that the fixing holes have the
correct depth and diameter. Always use all fixing holes.
When working with heavy loads exceeding 20 kg (44 lbs.), use suitable aids (dollies, hoisting
slings, etc.). Multiple persons may be required depending on the situation.
NOTE
WARNING
All screw connections should be checked when the BBT24 bracket is installed. If there are
loose screws, tighten them. If this is no longer possible, the screws and nuts must be repla-
ced.
When assembling and disassembling your system setups, make sure that you never care-
lessly remove the quick-locking pins of the BBT24 bracket with your fingers, hands or other
body parts or reach between the speakers. Due to the gravity of the upper part, it can fall
backwards or forwards.
There is a danger of crushing!
