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: Incoming supply → Power supply → Required control power 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?
