Site Requirements
Power
Make sure the power cord is compatible with the nominal power
source used with the WN-5220-V VideoWall.
Power Consumption
Power consumption of the WN-5220-V VideoWall is 920 Watts, or
approximately 8 Amps current draw at 115 VAC (4 Amps at 230
VAC). The WN-5220-V VideoWall can be configured to operate on
either 90-130 VAC or 180-260 VAC nominal power sources at 50/60
Hz.
Voltage Range
The operating voltage range of the WN-5220-V VideoWall is set via a
switch on the power supply near the AC power plug and on/off switch.
Operation of the VideoWall at the incorrect voltage level can cause
damage to the unit which is not covered by the warranty.
!"Select the setting labeled 115V if your power source is
between 90 and 130 Volts AC.
!"Select the setting labeled 230V if your power source is
between 180 and 260 Volts AC.
If the input voltage drops below approximately 85V (170V if the
WN-5220-V is set to the 230V setting) the display will automatically
shut down to protect itself.
On a typical 20A, 115V circuit, no more than two WN-5220-V displays
may be installed. This allows an extra current margin. If any circuit
used to power one or more WN-5220-V VideoWalls is not a dedicated
circuit, the additional electrical load placed on the circuit by other
equipment must be considered.
WARNING Displays that are intended for 240V configuration must
have a properly rated power supply cord and attachment plug
supplied by the installer.
WARNING If extension cords are used for power, use only 3-prong
grounded cords sized to handle system power requirements. Using
the wrong-size extension cord can cause a fire-safety hazard and can
reduce the voltage available to the WN-5220-V VideoWall. If the
extension cord is warm to the touch it is too small and should be
immediately removed from operation.

WN-5220-V VideoWall User’s Guide

Temperature and Humidity
The WN-5220-V VideoWall is designed to operate over an ambient
temperature range of 0°to 35°C (32°to 95°F) and a humidity of 20
to 80 % R.H. non-condensing.
Some types of environmental lighting, such as incandescent, or high
intensity discharge lamps such as metal halide or mercury vapor
lamps, create high temperatures and this can cause excessive
heating of the WN-5220-V VideoWall. VideoWalls should be
positioned far enough away from high-temperature lights to prevent
heat buildup.
Nearby heat sources can cause high operating temperatures in the
WN-5220-V VideoWall. Minimize the VideoWall’s exposure to heating
ducts, radiators, or other external heat sources.
Flooring
A single WN-5220-V VideoWall unit weighs approximately 120 lbs (55
kg). Before installing the WN-5220-V VideoWall, determine the
structural integrity of the flooring where it will be used. The floor
should be level and strong enough to support the combined weight of
the number of VideoWalls and other equipment used in the
installation. Take special care when installing a WN-5220-V
VideoWall in a wall configuration on a temporary structure such as a
stage floor, where the flooring could bend or collapse under the
weight of the installation. Never stack more than four (4) WN-5220-V
VideoWalls vertically on a temporary floor.
Clearance
Normal maintenance, such as lamp module and air filter replacement,
can be performed from the front or rear of the WN-5220-V VideoWall.
Maintain sufficient clearance to allow easy access from the front. A
minimum of 4 feet is recommended. For full maintenance from the
rear, the minimum recommended clearance is 3 feet.
To allow proper cooling, the minimum required clearance to the rear
of the VideoWall is 6 inches. The minimum required clearance to the
top at the front of the unit is 6 inches. See Environmental
Specifications on page 67 for cooling requirements.
If installed in a video wall configuration, a minimum of 12 inches to
the ceiling from the top of the highest VideoWall is needed if the units
are installed from the front.

Mechanical Setup
Install the WN-5220-V VideoWall in the desired position and connect
the power and signal cables. See the following section for an
explanation of the cabling configuration.
Figure 1
To setup the WN-5220-V VideoWall in a video wall configuration,
follow these steps:
1. Remove the screen
from each unit to be
used in the video wall.
Keep each screen with it’s unit. See Screen on page 45.
Place the screen where it will not be damaged.
2. Build the video wall. Build on a level floor strong enough to hold the weight of
the finished assembly. See Flooring on page 9 for weight
information
3. Assemble the lower row
first. Line up the legs as straight as possible.
Insert a ¼” X 2 ½” bolt through the holes as shown in
Figure 1. Tighten a nut securely on this bolt.
Secure the legs to the floor using the tapped 5/16-18
holes in the front and rear of the legs when stacking more
than two units high or use the optional BAS-520 base to

Tighten a nut on this bolt to lock the units together. See
Figure 1 above.
6. Continue with
subsequent rows of
VideoWalls
Lock each VideoWall to the adjacent VideoWalls after the
row above it (if any) has been installed.
7. For added stability… Use the rear-tapped holes in the legs of the upper units to
fasten to a solid support, such as a structural wall.
The threaded inserts in each leg are female 5/16-18 UNC.
8. Check Check that all VideoWalls in the video wall are locked
together.
9. Reinstall screens Reinstall each VideoWall’s screen.
Cables
Video connections from the signal source to the WN-5220-V
VideoWall depend on the type of signal supplied by the source. The
compatible video inputs are; 640x480 VGA, Mac II and 31.5 kHz
RGBS Video. With the optional VIM line-Doubler/Scaler card 15.75
kHz RGBS Video is recognized and with the optional VIM decoder
card Composite Video and S-Video will be processed and displayed.
The Loop-thru video output uses a standard 15 pin VGA type
connector for output to an external computer monitor or another
VideoWall. The format of the Loop-thru video is same as the source
video. VGA and MAC II will have RGB with separate H-Sync and V-
Sync. RGBS video will come out RGBS with the composite sync on
the connector’s H-Sync pin. RGB Sync on Green sources will loop-
thru RGBS-Sync on Green. VideoWall displays with the optional
VIM-200 option using a Composite Video or S-Video source will not
output a loop-thru signal for those two sources.
The video cables used should be high quality and shielded to insure
the best image quality when displayed.
Using poor quality cables can lead to picture noise, jitter and
crosstalk.
Control data enters the VideoWall via the RS-232 In connection, and
is supplied to an adjacent VideoWall (if used) via the RS-232 Out
connector. High quality shielded cables designed for RS-232
communication should be used to ensure proper data transmission
and control.
