The title block restricts reproduction, so these files and derived previews are not hosted here. Legacy manufacturer download index; confirm current local product availability, electrical ratings and applicable approvals with Altech. The manufacturer index maps drawing group CBI12xx to CBI123A, CBI126A, CBI1210A, CBI1235A. Voltage/current aliases stay on this single family page because the index links them to one mechanical file set. Reserve separate routes for supply, battery and backed-up load conductors; the battery is not included in the device outline. This is a legacy CAD source: confirm current product status, installation clearances and the applicable revision with Altech; the file group alone does not establish electrical ratings, approvals or interchangeability. ## In plain English ### What the equipment does A UPS uses stored energy or another designed supply arrangement to keep selected loads powered when the normal supply is interrupted. ### A simple example In a substation, a UPS can keep communication and monitoring equipment running through an interruption of their normal supply. ### What the drawings help you do Use an outline or mounting drawing to plan where the equipment fits and where it attaches. Use a connection drawing to trace its electrical interfaces. A 3D model helps coordinate space; check the manufacturer's installation requirements separately. ### Terms - CAD: Computer-aided design files used to prepare drawings and models. - Revision: The recorded version of a drawing or model. Concept diagram: Normal supply and stored energy → UPS → Supported equipment A simplified explanation of how this item works. It does not show terminal wiring or an operating procedure. - [Altech official source](https://legacy.altechcorp.com/CAD/1MasterSheet/WebsiteUSE/HTMLWebpages/PowerSupplyMasterSheet.htm) ## Which file should I choose?
