3.0 OPERATION
3.1 Display Screen and Operator Controls
Each Liebert Series 610 UPS cabinet is equipped with a microprocessor-based Operator Control Panel
and Display Screen and System Control Panel designed for convenient and reliable operation. The
System Control Cabinet (SCC) performs different functions than the UPS modules. Each cabinet has
the controls and displays required to operate and monitor its functions. The locations of operator con-
trols are shown in Figure 8 through Figure 11.
The front location of the control panel enables the user to quickly identify the current status of the
UPS system and to perform most of the manual operations. The operator display screen is driven by
an easy-to-follow menu-prompted software program.
