2.3 Major Components
This section provides a general description of each component and its functions. Please review this
section carefully, as it will give you a better understanding of how the UPS operates.
2.3.1 UPS Frame
All UPS components are located in the Liebert APS frame. The front of the UPS consists of a series of
plastic bezels. Grasp the bezels from the sides and pull straight out to remove the bezel and reveal the
battery/power-module bays. The standard-model frame provides cooling fans and a manual-bypass
breaker on the top. The transformer-model frame provides a manual-bypass breaker on its bottom and
fans on both top and bottom. The user-interface module is located above the power/battery-module bays
for easy access, operation and for viewing UPS operating information. On the lower-right of the user-
interface module are the system-control module bays.The UPS frames are shown in Figure 2.5 below.
NOTE: In the figure, the power module and battery module are extended for illustration purposes only.
Extending more than one module at a time could cause the unit to tip over.
