Cleaning and Maintenance

Use the procedures in this section to remove and replace WN-5220-S
modules as needed to maintain trouble-free operation.

Screen

The WN-5220-S has two screen options:
•
The standard screen has a mullion about 1/8
The mullion is a strip of sheet metal surrounding the screen which
holds it in place.
•
The Ultra-Thin Mullion Screen, or mullionless screen, does not
have the 1/8
viewing area of the screen goes right to the edge of the display
unit. This makes the lines between display units much less
apparent in the finished video wall.
With standard screens, electrical interlocks prevent operation when
the front screen is removed. Do not operate the display with any
access panels or the front screen removed from the unit, except when
required for servicing. Operating the display with access panels or the
front screen removed can expose service or operating personnel to
ultraviolet burns and high electrical voltages. Always wear ultraviolet-
blocking eyewear with side guards when servicing the display.
For Standard Screens, removing the screen provides service access
to other replaceable modules from the front of the display. Service
access for Ultra-Thin Mullion Screens in done more easily from the
rear access panel.
