6.1 Proper Ladder Use
A ladder can be used to access displays,
although it is not preferable. If a ladder must
be used, do not place the ladder directly
against the display face. The pressure from the
two ladder ends, even when covered with
pads, is too concentrated and can damage the
LEDs and louvers.
Instead, use a padded or carpeted board across
the top of the ladder to distribute the weight of
the ladder evenly when placed against the
display face. The padded board should be
wide enough to spread the weight of the
ladder across a minimum of two modules.
6.2 Access to Display Interior
To access the display’s interior:
1. Disconnect power to the display.
2. Locate the latch access fasteners shown in Figure 15 on the module.
3. With a 1 /
8
"hex wrench, turn the latch access fasteners counter-clockwise a quarter
turn. Gently pull the module far enough forward to reach the power and ribbon
cables as shown in Figure 16.
