apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
14. The appliance coupler (AC Mains plug) is the AC mains disconnect device and shall remain readily operable after installation.
15. Adhere to all applicable, local codes.
16. Consult a licensed, professional engineer when any doubt or questions arise regarding a physical equipment installation.
17. Suspension of this product should be done by qualified persons following safe rigging practices. Other limitations may apply.
18. Use only the recommended system components and suspension hardware intended for use with this product as directed by this
manual.
Rigging Safety Regulations:
• 2006/42/EC
• EN ISO 12100-1: 2004
• EN1991-1 / EN1993-1-1 / EN1993-1-8 / EN1999-1-1
• DGUV Vorschrift 17/18
• ANSI E1.8-2018
General Rules for Suspension
• Consult a professional mechanical or structural engineer, licensed in the jurisdiction of the sound system installation, to review, verify,
and approve all attachments to the building or structure.
• Employ the services of a certified, professional rigger for hoisting, positioning, and attaching the equipment to the supporting
structure.
• Correct use of all suspension hardware and components is imperative in sound system suspension and deployment.
• Always calculate suspended loads before lifting to ensure suspension components and hardware are used within their respective
load limits.
• Consult local codes and regulations to fully understand the requirements for suspended loads in the venue in which equipment will
be suspended.
• Use only dedicated QSC LA108-AF and/or QSC LA112-AF array frames or the QSC LA-KIT-I installation kit for suspending a
loudspeaker array. Further details can be found below.
• Be absolutely certain of the integrity of any structural member intended to support suspended loads. Hidden structural members can
have hidden structural weakness.
• Never assume anything! Owner or third-party supplied suspension attachment points may not be adequate for suspending the
loads.
• Before lifting, always inspect all components (enclosures, suspension brackets, pins, frames, bolts, nuts, slings, shackles, etc.) for
cracks, wear, deformation, corrosion, missing, loose, or damaged parts that could reduce the strength of the assembly. Discard any
worn, defective, or suspect parts and replace them with new, appropriately load-rated parts.
