Do not remove both the control and the monitor modules at the same time. Removing both the
control module and monitor module at the same time will cause the UPS to shut down and
remove power from the load. Replace these modules one at a time.
1. Remove the display bezel and the user interface (LCD) module from the frame, as shown in
Figure 3.11 below, then lay the user-interface module on top of the UPS.
