4. Disconnect the two ribbon cables from the module by spreading the tabs on the sides
and then lifting the cable
head from the jack. Note
how they are connected to
the back. A generic display
module is shown in Figure
15.
5. Unplug the power cable by
squeezing the tabs on the
sides of the plug head and
pulling out.
6. When ready to reinstall the
module, reconnect the
cables to the module,
making sure the tabs are
tightly pushed against the
cable head. Carefully push
the ribbon wires back into
the cabinet so they are clear
of the module edges.
7. Place the module into its proper location, checking that the weather stripping is in
place. Latch the module both top and bottom by turning the hex wrench clockwise a
quarter turn.
Weather stripping on the module’s back edge must be intact and in good condition to
prevent water from seeping into the display.
Module latches must be fully engaged to create a watertight seal around the module’s edge.
The module must be firmly seated against the display when the latches are fully engaged.
6.3 Ventilation System/Fans/Filters
Frequency of Inspection
Ventilation fans, located along the bottom of
the display, pull air into the cabinet from
lower vents and exhaust air either out upper
vents, as shown in Figure 4 or adjacent lower
vents, as shown in Figure 17.
Check the fans every time the display is
opened or at a minimum of every three
months. Check more often if the display is
located in a dusty or harsh environment, such
as along a gravel road.
The frequency of inspection will vary greatly
