3.4 Installing the safety cable
About this task
After mounting the DSR1090 to the building structure with a bracket or yoke, you must follow instructions for
connecting a safety cable to an independent point on the building structure.
These tools and additional parts are required to install the safety cable:
• 6 mm hex driver.
• An M10 shoulder-style eyebolt. The eyebolt can be provided by the installer, or you can purchase an
appropriate M10 eyebolt (separately) from Dolby (Part number: 6009242).
• Installer-provided safety cable.
Attention: To properly fit into the DSR1090 threaded inserts the eyebolt must contain a threaded
shaft that is at least 20 mm long. Based on the weight of the DSR1090 (31 lb [14 kg]), all installer-
supplied safety rigging hardware must be rated at a minimum 5:1 safety factor, or greater if a higher
requirement is mandated per local laws. Remove all slack to avoid any shock loading of the cable in
the event of a primary rigging failure.
Procedure
1. Locate the safety eyebolt mounting location on the back of the DSR1090.
2. Remove the corresponding M10 bolt from the cabinet using the 6 mm hex driver.
3. Remove the M10 eyebolt from the packaging, and then place it in the selected M10 threaded hole.
4. Secure the eyebolt firmly, and then attach the installer-provided safety cable to the building structure.
