Attaching WL2082-i to Array Frame

Before beginning any installation, have your system designer configure the array with proper splay angles using QSC’s EASE Focus (Array Calculator). All orientation of product is to be as

viewed from the rear of the enclosure.

Figure 7: WL2082-i attached to FB2082-i

 

Attach the array frame to the suspension structure using a 3/4” (20 mm) screw pin anchor

 

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

 

For arrays of 4 WL2082-i or less, assemble the cluster of WL2082-i on the ground using the

 

included mating hardware. Ensure the notched rigging plate is on the right hand side (the sys-

 

tem can only be installed one way. Note the QSC logo on the input plate will be right side up

 

when the enclosure is oriented properly). During assembly, ensure your splay angles are as

 

desired.

 

When constructing large arrays it is recommended to first assemble units of four enclosures

 

and then assemble the final array by joining the four enclosure units to one another.

 

Attachment of one enclosure to another is accomplished by inserting the cap-head shoulder

 

bolt with washer through the rigging plate attachment holes and appropriate splay angle

 

selection holes in the mating rigging plates and threading the lock nut (nylock) on the inside

 

edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft of torque (6.8

 

N-m). See Figure 7 for assembly detail.

 

Attach the array frame to the top enclosure by inserting the cap-head shoulder bolt with

 

washer through the appropriate mounting holes and threading the lock nut (nylock) on the

 

inside edge of the plates. The bolt should be tightened snuggly to no more than 5 lb-ft (6.8 N-m)

 

of torque.

 

NOTE: For some array configurations, use of the extension bar and/or pull-back

 

may be required to achieve the required aiming angle.
