PS-RDN supply redundancy accessory arrangement for DC control-panel layouts.

## In plain English

### What it does

A power-supply redundancy module combines suitable supply paths so the connected load can remain powered if one source is lost, within the designed arrangement.

### A simple example

In a substation control panel, it can connect two independent DC supplies to a common supported load.

### What the drawings help you do

Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.

### Terms

- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

The manufacturer index maps drawing group PS_RDN to PS-RDN. Coordinate the accessory between the independent supply inputs and the common output wiring; verify the actual electrical topology separately.
Use the linked manufacturer mechanical original for dimensions and exact revision. This illustration is independently drawn, unitless and not to scale.

## How to read it

- Show both input routes and the common DC output corridor.
- The accessory outline does not establish the allowable redundancy topology, current rating or protective-device selection.

## Information to show or reference

- Identify the exact PS-RDN accessory.
- Show both input routes and the common DC output corridor.
- Check independent supply positions and accessory terminal access.

## Important distinction

The accessory outline does not establish the allowable redundancy topology, current rating or protective-device selection.
