INSTALLATION
IMPORTANT ! :
Refer to
Dimensions
section at end of
instructions to find specific LCM video wall dimension
requirements
BEFORE
proceeding with installation.
NOTE:
The following procedure assumes that 2 UL Listed CPA
or CMA ceiling plates (not included) and 2 extension
columns (not included) have been properly installed
following instructions provided with ceiling plates and
extension columns.
•
The ceiling plates and columns should be installed
approximately spaced at center of outside
screens. (See
Dimensions
drawings at end of
instructions.)
IMPORTANT ! :
The weight of the system should be
evenly distributed across two ceiling plates.
Installing Array Offset
1.
Measure depth of screens to be installed and compare to
offset position information. (See Table 1)
Table 1: Offset Position for Screen Depth
NOTE:
The array offset (N) ships in the centered position. If the
screen depth is 2.5" to 4.5" leave the array offset as is,
and proceed to
Attaching Array Offset to Installed
Column
section.
2.
Loosen and remove fastener and washer from center hole
on each side of array offset (N). (See Figure 1)
3.
Loosen two outside fasteners on each side of array offset
(N).
4.
Slide offset to appropriate position. (See Figure 1)
5.
Tighten two outside fasteners on each side of offset.
6.
Install and tighten fastener with washer (removed in Step 2)
into appropriate hole on each side of offset. (See Figure 1)
Figure 1
7.
Repeat for remaining array offset (N).
Attaching Array Offset to Installed Column
NOTE:
If the column attached to the ceiling plate is a 1-1/2"
NPT column, the UL Listed CPA261 adapter accessory
(KK) must first be installed following instructions
included with the accessory. No adapter is necessary if
attaching to a UL listed CPA extension column.
NOTE:
Installation of hex head self-tapping screws will be
easier when screws are carefully aligned with holes in
extension column, and a drill and nut driver is used. If
a drill will NOT be used, a small amount of pressure will
be needed to get the self-tapping screws started.
1.
Secure array offset (N) to extension column (not included)
using four 5/16-18 x 1" hex head self-tapping screws (S),
four 5/16" split lock washers (T) and four 5/16" flat washers
(U) through holes in extension column. (See Figure 2)
2.
Install two 5/16" x 1/2" set screws (R) into threaded holes,
tightening firmly against column. (See Figure 2)
