Owner's Manual Rigging Rigging Hardware and Accessories SRM550 and SRM650 loudspeakers may be individually flown using a PA-A2 Eyebolt Kit, part number 0028272 [M10 x 1.5 x 37 mm forged shoulder eyebolts]. WARNING: Installation should only be done by an experienced technician. Improper installation may result in damage to the equipment, injury or death. Make sure that the loudspeaker is installed in a stable and secure way in order to avoid any conditions that may be dangerous for persons or structures. WARNING: The cabinet is suitable for rigging via its fly points. NEVER attempt to suspend an SRM loudspeaker by its handle. Rigging Design Practices Rigging a loudspeaker requires determining: 1. The rigging methods and hardware that meet static, shock, dynamic, and any other load requirements for supporting the loudspeaker from structure. 2. The design factor and required WLL (Working Load Limit) for this support. We strongly recommend the following rigging practices: 1. Documentation: Thoroughly document the design with detailed drawings and parts lists. 2. Analysis: Have a qualified professional, such as a licensed Professional Engineer, review and approve the design before its implementation. Rigging our loudspeakers will invariably require hardware not supplied by us. Various types of load-rated hardware are available from a variety of third-party sources. There are a number of such companies specializing in manufacturing hardware for, designing, and installing rigging systems. Each one of these tasks is a discipline in its own right. Because of the hazardous nature of rigging work and the potential liability, engage companies that specialize in these disciplines to do the work required. We do offer certain accessory rigging items and some of them may be used with a variety of products. While these accessories are intended to facilitate installation, the wide variety of possible installation conditions and array configurations do not permit us to determine their suitability or load rating for any particular application. We are not in the business of providing complete rigging systems, either as designers, manufacturers, or installers. It is the responsibility of the installer to provide a properly engineered, load-certified rigging system for supporting the loudspeaker from structure. Rigging Notes The SRM loudspeaker's integral mounting points are designed to support only the weight of their own loudspeaker with suitable, external hardware. This means that each SRM loudspeaker must be supported independently of any other SRM loudspeaker and any other loads. All three rigging points must be used to hang an SRM loudspeaker. 3. Installation: Have a qualified professional rigger do the installation and inspection. 4. Safety: Use adequate safety precautions and back-up systems. 3 Fly Points MP = Mounting Point MP MP Top MP Rear Owner's Manual 17
