Compact stand-alone generator controller with an icon display and front programming interface.

## In plain English

### What it does

A generator controller monitors and manages a generating set, including starting, stopping and reporting alarms.

### A simple example

In a microgrid, the controller can start a standby generator when the site's control system requests more generation.

### 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

- Rating: A value stating the conditions for which equipment is specified.
- Schematic: A drawing showing function and connections rather than physical appearance.

## What it represents

Use the RGK400SA model for the smaller operator-panel opening. Arrange the faceplate for clear indication and locate rear wiring so the controller can be removed without disturbing adjacent equipment.
Use the linked manufacturer CAD for dimensions and the exact selected configuration. The downloadable illustration here is original educational geometry, unitless and not to scale.

## How to read it

- The manufacturer lists 12/24 V DC supply and optional expansion capability. Include fitted expansion parts in the rear envelope.
- RGK400SA and RGK600SA have different front sizes; their cutouts are not interchangeable.

## Information to show or reference

- Use the RGK400SA dimensional file.
- Record fitted expansion accessories.
- Check connector access, wiring slack and visibility.

## Important distinction

RGK400SA and RGK600SA have different front sizes; their cutouts are not interchangeable.
