Note: The rails are not designed to hold an enclosure that is partially inserted.
The enclosure must always be in a fully inserted position. Control enclosures
must be installed only on the supplied control enclosure rails. Do not install a
control enclosure on expansion enclosure rails.
4. Secure the enclosure with screws in the rack mounting screw holes on each side
of the enclosure. (See Figure 18.)
Some enclosures are secured by one silver captive screw and one black M5
screw on each flange. In this case, align the enclosure, fasten the two captive
screws, and then fasten the two M5 screws. See Figure 19
5. Reinstall the left and right end caps. (See Figure 20 on page 22.) The left end
cap has indicator windows that align with the status LEDs (light-emitting
diodes) on the edge of the enclosure.
a. Ensure that the serial number on the left end cap matches the serial number
on the left flange ("ear") on the front of the enclosure.
b. Fit the slot on the top of the end cap over the tab on the flange.
c. Rotate the end cap down until it snaps into place.
d. Ensure that the inside surface of the end cap is flush with the flange.
