Rigging the Installation Line Array (continued)

Pull-Back Bar

If using the pull-back bar, attach to the bottom enclosure at the bot- tom-most splay angle adjustment holes at the rear of the rigging plate by inserting the cap-head shoulder bolt through the mated pieces and threading the lock nut (nylock) on the inside edge of the plates. Use a 5/8” (16 mm) shackle to attach to the pull-back bar shackle hole located in the center of the main bar.

NOTE: All hardware/components must be rated for the expected loads as determined by the Professional Engi- neer responsible for suspension.

NOTE: A washer should not be used when attaching the pull back bar. This will allow the pull back bar to pivot freely.

Extension Bar

The extension bar rigging plates can be moved, if required, by remov- ing the two 7/8”mounting bolts, moving to the selected mounting location, and reattaching. Tightening torque is to be 100 lb-ft of torque (135.6 N-m) Ease-Focus software’s center-of-gravity calculator will provide a suitable point (or two points) for desired down-tilt.

Attach the array frame to the extension bar rigging plates by centering the array frame member between the extension bar rigging plates and bolting together using the supplied 7/8” bolts.

Attaching the WL115-sw to the Array Frame

All orientation of product is to be as viewed from the rear of the enclo- sure. The QSC logo on the input plate will appear right side up when the enclosure is oriented properly.

1- Attach the array frame to the suspension structure using 3/4" (20

mm) shackle and appropriate sling, cable, etc....

2- Refer to Figure 10. For all four rigging straps: Using an 6mm hex wrench, remove the upper and lower rigging strap retaining bolts and loosen the two bolts in between. Pull the inner and outer straps to their outermost position; pull the center strap to its outermost posi- tion, and align the retaining bolt holes with the threaded inserts of the enclosure. Re-install the outermost rigging strap retaining bolts and tighten all four bolts on each strap to 13 lb-ft (17.6 N-m).
