Figure 26
shows all possible Frame 9 configured input bay upper door external components. Your
configured input bay may only have some of these components. You can also use Figure 26
to
identify internal door components. The basic internal door components common to all frame 8
and 9 configured input bays with input protection are shown in Figure 27 on page 30
