TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Components: The UPS system includes second frame component. The second frame component is coupled to the first frame and is capable of holding module(s). The second frame component is coupled to the first frame component by at least two support mechanisms attached to respective side portions of the first and second frame components. The system includes door component including faceplate components. The door component is removably mounted to a front side of the UPS system. The number of faceplate components depends in part(s) on the height of the frame component(s). The faceplate component(s) can be used in two different doors with different heights. The door component includes bezel component(s) that is installed in the other door component(s) with different height than the door component. The door component includes sidepieces formed to suit the height of the UPS system. The door component is used to accept bezel components. The number of bezels accepted by the door component depends on the door height. The door component includes frame. The bezel component(s) is attached removably in the doorframe. The doorframe is removable independent of the other bezel components. The bezel component(s) includes acrylic plastic. The door component is removable from the front of the UPS system or is removably attached to the bottom or top edge of the door to a frame of UPS system. The first frame component includes covers if configured in stand-alone unit. The cover(s) is coupled to the exterior surface of the first frame component. The UPS system is standalone configuration. The first frame component is capable of accepting caster(s). The UPS includes battery module. The battery module is capable of being installed in the first frame component in a first orientation. The battery module is capable of being installed in the second frame component in the second orientation. The two orientations are not the same orientation. The first frame component includes support coupled to the rack and supporting the first frame component as it is positioned in the rack, if first frame component is installed in rack-mounted UPS system. The support is supports the first frame from underneath the first frame component. The support includes secondary support when the first frame component is positioned in the rack prohibiting vertical movement of the first frame component. The secondary support is coupled to the first frame component through an opening in the first frame component when the first frame component is fully inserted in the rack. The secondary support is coupled to the first frame component without requiring rear access to the rack. The support includes associated support positioned in an opposing side of the rack. The battery module includes connector connectable in at least two different orientations, handle for inserting and removing battery module, third alignment mechanism coupled to the fourth alignment mechanism associated with second frame portion of another of the at leas two different types where the battery module is inserted when the battery module is in second orientation with respect to the second frame portion. The connector is electrical connector. The electrical connector is used to provide backup power to load(s) associated with UPS system. The handle has at least two different orientations. The battery module includes first alignment mechanism coupled to the second alignment mechanism associated with first frame portion of at least two different frame types where the battery module is inserted when the battery module is in first orientation with respect to the first frame portion. The battery module is installed as part of the UPS system containing core frame type and expansion frame type. The expansion frame type is capable of storing additional battery modules. The battery installed in the core frame type and battery installed in expansion frame type is the same type of battery module. The same battery type is used in the core UPS frame type and expansion frame type. The rear support is C-shaped portion engaging opening of rack-mounted system. The support rail is used to be installed on interior side of the rack. The ledge piece extends into the interior of the rack. The support rail includes two rail portions. The first rail portion is insertable in the second rail portion allowing the support rail to be extended to varying lengths between front and rear vertical mount rails. The support rail is made in part(s) of steel material. The support rail is installed as part of the support system including another support rail positioned on opposite vertical rails in the rack.
