CRA24/ 30 array assembling
The numbers in the text below, correspond with the CRA30 overview pictured earlier.
The CRA24/ 30 system can be stacked onto a cinema screen frame. This is the default set-up. It is intended for
indoor use only.
The CRA30 system is scalable with 1x CRA30W + 1x CRA30N or 1x CRA30W + 2x CRA30N
It is not possible to attach 2x CRA30W to each other.
A stacked CRA24 system is scalable with 1x CRA24W + 1x CRA24N or 1x CRA24W + 2x CRA24N
Mount two CRA30 stack feet (7) at both sides of the CRA30W cabinet. They can be screwed in place with two
M10x16 screws
For scratch protection, place a carton sheet on top of the CRA30W cabinet and place the next CRA30N cabinet on
this sheet, with the front corners aligned. This is a two man job.
Attach the front couplers (5) and the angle arms (4) on bottom sides of the top CRA30N cabinet. Use the supplied
M10 screws. They have a 8.8 strength class with a max. thread length of 16mm/ 0.63"
Do not tighten up the screws at this moment. This gives more clearance when assembling the next cabinet. Attach it
to the front couplers. Make the angle arm connection, with the correct angle adjustment.
Repeat this mounting procedure with an optional second CRA30N cabinet. Tighten up all front coupler and angle arm
screws. Tilt the complete array on the stack feet to the correct alignment (17° variable) and tighten these screws up
firmly. The stack foot can be screwed to the screen frame for extra safety
Connect all cabling to the signal input panels (6) and ensure that the cable weight is supported by a dedicated cable
suspension.
