## In plain English

### What the equipment does

A louver provides an air opening with blades that help manage weather entry or airflow according to its design. It does not move air by itself.

### A simple example

On a switchroom exterior wall, a selected intake louver can admit ventilation air while providing the specified weather protection.

### 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.
