Figure 1.2: Attaching Rack-Mount Ears
NOTE:
Before installing the rack-mount ears, you might want to determine if you need to
configure anything inside the 1133A (e.g. Event Inputs). To install the rack-mount ears requires
removal of the top cover screws, which if required would be a good time to make any changes. See
Chapter 14, Event Input Voltage Settings, for information on making changes to any of the Event
Input modules.
