Figure 20 illustrates the component locations of an 8x48-34mm display with all modules
removed. This layout will be similar for 8x32-34mm cabinets as well. Note that 8x48-34mm
cabinets with white LEDs require an additional power supply behind the fourth module.
Refer to Drawing B-975100 in Appendix C.
Figure 21 illustrates the component locations of a 16x80-34mm display with all modules
removed. Note that cabinets do not have four power supplies; this is a composite illustration
that shows the possible locations for all LED colors. Refer to Drawing C-1092559.
Figure 22 illustrates the component locations of an 8x48-46mm display, and this layout will
also be similar for 8x32-46mm cabinets. Note that 8x48-46mm displays with white LEDs
require an additional power supply behind the fourth module. Refer to Drawing B-975635.
