Maintenance

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

Front Access

1. Disconnect power to the display.

2. Locate the latch access fasteners shown in Figure 23 on the module.

3. With a

turn, as shown in Figure 24. Gently pull the module far enough forward to reach the

power and ribbon cables.
