Take the top cabinet angle arm out of the transport position and put the red pin (9) in.
Choose the angles of al cabinets by aligning the angle pin (4) with the bottom compression fly slot in the angle arm (5).
The angle setting can be done at the warehouse or on-site. There will be pressure on the red pin (9) when adjusting the angle arm (5).
A slight push/ tilt against the overlying cabinet will also help to ease this pressure.
When the first cabinets are ready, attach GRD24B to the top cabinet (A). Attach the audio cabling and use a hoist sling to take the weight of
the speaker cables
Attach a manual 0,75T lever hoist, with overload protection, from the bottom 3.25T shackle position on the GRD24B. Be sure to have
sufficient chain length. Use an extra safety chain in combination with the lever hoist. It is not allowed to use a motor hoist.
Take the PRRGL24 off when the first pack is suspended. Remove all the red buttoned 0° pins (9) and place them in the rubber lined
parking holes
Position the next PRRGL24 pack under the suspended array (C). Ensure that all angle adjustments are done.
Lower the suspended array to make the three point connection (front co angle arm coupling). You can remove the top red 0° pin to
make the back connection easier. When finished and the combined array is suspended in the air (D), pull out all red buttoned pins (9).
Continue this procedure until full array length is reached.
End with attaching the PBFRML24 under the lowest cabinet. Mount the frame onto the front couplers (2) and lock with their pins. Make the
connection with the lower cabinet connecting pin (8) and lock it (D)
Start hoisting the (lever) hoist to set the cabinet angles (E). This has to be done by an authorised person. Stop when there is no more slack in the array. This
can be checked by pushing the array back and forth and listening for any slack noises in the angle setting frames.
Do not over-compress the array, as this can cause damage to the suspension system !
After the compression stage, the angle of the entire array can now be adjusted. Use an angle inclinometer on the GRD24B.
