1.2.5.1.2. Cautions for screen
Because 8 80 0” ”screens are large and heavy, the screens should be held carefully.
• To prevent the screen from damage or breakage, carry the
screen by two or more people.
• Hold the short sides of the screen frame or the corners
when picking up the screen. Holding the center of the long
sides of the frame (between labels) may damage the
screen edge due to its heavy weight.
• Do not lay the screen with face up on the floor or table. The screen frames may not support
the heavy and large screen surface.

1.2.5.2. Assembling the base stands and cubes
Note:
• Combining many cubes may accumulate the tolerance of screen sizes, which causes
difficulty to keep appropriate screen gaps (in chapter 1.2.5.3, on page 13). In such cases,
especially horizontally long display walls, it is recommended to insert spacers between cube
cabinets at any given distance preliminarily.
1. Assemble base stands.
2. Adjust level adjusters to make the base stand both
level and plumb by means of a spirit level.
3. Loosen 4 screen-fixing screws per unit shown
with arrow lines in the right figure with an Allen
wrench (5 mm) to remove the screen units
from all cubes to be installed. (This applies to
5
50 0” ”, which is supplied with the screen fitted).

According to circumstances, attach the optional external AC fans (JC-AF115R or JC-AF230R) on
the intake vents in the bottom row (see “External AC fan attaching” on page 19).
• Prepare openings on base stands to ventilate.
• Keep enough base stand height not to inhale a coat of dust on a floor from the intake vents.
1. To block the bottom row, detach the bottom duct cover from inside the cube and attach it on
the bottom of the duct. Be sure this work is only for the cubes in the bottom row.
2. To block the top row, remove the cushion unit on the top at first. Then detach the top duct
cover from the top surface of the cube and attach it on the top of the duct. Be sure this work
is only for the cubes in the top row.
3. To keep dust out, seal the cable holes on the top of the display
wall. Prepare a cover material by yourself. The size of the
holes is 116.5mm x 63mm. Be sure this work is only for the
cubes in the top row.

External AC fan attaching (occasional)
When 4-high configuration with 5 50 0” ”S Si in ng gl le e, attach the optional external AC fans (JC-AF115R or
JC-AF230R) on intake vents. Even in 3-high configuration, attach the AC fans as well, when
spaces are narrower than 50cm to the ceiling and 10cm to the wall behind. Narrow spaces tend
to rise the cube internal heat. Be sure this work is only for the cubes in the bottom row.
1. Attach a suitable plug to the bare end of the power
cord of the fan to correspond with an interface such
as a terminal block or a power strip. 2-meter AC
power cord is included in the fan.
2. Insert the fan into the intake vent till click.
3. Fix it to the lower part of cube with the screw supplied
with the fan.
Note:
• To avoid injuries and shock hazards, do not carry
electricity to the fan during this work. It must be done
by qualified personnel.
• Be sure to use the fan within the range of its power
rating.
• The outline of the fan is shown below. Prepare a base stand which does not interfere with the
fan.

1.2.6.4. Assembling base stands and cubes
Note:
• Combining many cubes may accumulate the tolerance of screen sizes, which causes
difficulty to keep appropriate screen gaps (in chapter 1.2.6.5, on page 21). In such cases,
especially horizontally long display walls, it is recommended to insert spacers between cube
cabinets at any given distance preliminarily.
1. Assemble base stands.
2. Adjust level adjusters to make the base stand both level and
plumb by means of a spirit level.
3. Place a cube on the base stand.
Caution
Do not grip the screen-holding arms to
lift up a cube cabinet. It may cause
breakage.
4. Fix the cube at 4 points with supplied hexagon
socket head bolts, spring washers and flat
washers.
Caution
When holding up a cube, be careful not
to put your hand between the cube and
the base stand.
5. Place the next bottom row cube on the base stand and fix it in
the same way.
6. Join right and left cubes at 4 points with supplied hexagon
socket head bolts, spring washers and flat washers.
7. Place cubes for the upper row on the assembled units.
8. Fix them vertically and horizontally at 4 points each with
supplied hexagon socket head bolts, spring washers and
flat washers.
9. Stop up the holes on both sides with supplied joint hole
seals, which holes are not used for a display wall.
10. Run cables through the internal cabinets according to the
chapter 1.3.3 on page 26 before attaching the screen unit.
Caution
To avoid units from falling, measure horizontal and
vertical degrees with a level etc. to make sure the units
are stably assembled.
