Shows the command and feedback connection of a manufacturer-provided racking drive.

## In plain English

### What this block does

Shows the command and feedback connection of a manufacturer-provided racking drive.

### A simple example

In a medium-voltage switchgear drawing, the operating reference helps the reader distinguish the interrupting device from its isolation, earthing and auxiliary-control interfaces. For this reference, the drawing identifies “Racking command and readiness” at the input and “Racking-drive action” at the output. Remote operation does not remove equipment interlocks.

### What the drawings help you do

Start at the named input: Racking command and readiness. Identify its source device or document and the state represented on the drawing. Follow the named output: Racking-drive action. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Racking command and readiness
- Output: Racking-drive action
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Shows the command and feedback connection of a manufacturer-provided racking drive. A switching-device operating reference adds the specific mechanism or duty context needed to interpret its place in a power circuit. The same basic switching outline can serve different equipment constructions, so the added description must remain attached to its device tag.
In a medium-voltage switchgear drawing, the operating reference helps the reader distinguish the interrupting device from its isolation, earthing and auxiliary-control interfaces. For this reference, the drawing identifies “Racking command and readiness” at the input and “Racking-drive action” at the output. Remote operation does not remove equipment interlocks.
Use the device schedule for its actual construction, operating duty and ratings. These original functional illustrations describe the named role and do not certify a standard glyph or product footprint. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Racking command and readiness. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Racking-drive action. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- Remote operation does not remove equipment interlocks.
- Use the device schedule for its actual construction, operating duty and ratings. These original functional illustrations describe the named role and do not certify a standard glyph or product footprint.

## Information to show or reference

- Label the source and connection reference for racking command and readiness.
- Identify the destination and defined state of racking-drive action.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: Remote operation does not remove equipment interlocks.

## Important distinction

Remote operation does not remove equipment interlocks. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.

## Facts

- Representation: Functional block
- Installation focus: Switchgear
- Input / boundary: Racking command and readiness
