• All rigging should be performed by certified, trained personnel.
• Proper chain motor installation and operation is absolutely necessary under all circumstances.
• L-ACOUSTICS recommends the use of safeties at all times.
• Always refer to MECHANICAL DATA in ARRAY2004 or SOUNDVISION to ensure that safe
rigging conditions apply before installation.
• Ensure that the immediate area is clear of people and obstacles whenever raising or lowering the
array. Announce (in a loud voice) whenever the array is being moved to get people’s attention.
Always look up while moving the array to be sure that movement remains unimpeded and to
check cable tension. Once flown to trim and correctly angled, remove motor control cables so
that the array cannot be tampered with by unauthorized people. Always cover motors with plastic
if motors might be exposed to rain.
• When flying dV-DOSC and/or dV-SUB, determine the overall weight of the system to be flown
and determine chain motor ratings accordingly.
• When dV-DOSC is flown on top of, or below V-DOSC account for the additional weight and
adjust your chain motor ratings accordingly.
