emonTx3 monitor board and current-sensor interface layout reference.

## In plain English

### What it does

An energy meter adds up electrical energy over time, rather than showing only the power being used at one moment. The units identify the type of energy recorded.

### A simple example

In a microgrid, a feeder energy meter can record how much energy a process used during a shift.

### 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.

Concept diagram: Power measurements over time → Energy is accumulated → Recorded energy total

## What it represents

Coordinate the selected PCB revision, external sensor sockets and low-voltage connections with the intended enclosure.
Use the linked manufacturer drawing or project mechanical files for dimensions and the exact selected revision. This original educational illustration is unitless and not to scale.

## How to read it

- Check mounting, enclosure fit and connector approach.
- The monitor board is not a current transformer, revenue meter or a complete approved mains measurement enclosure.

## Information to show or reference

- Record repository revision and mechanical files used.
- Check mounting, enclosure fit and connector approach.
- Review electrical isolation, thermal design and applicable approvals before use.

## Important distinction

The monitor board is not a current transformer, revenue meter or a complete approved mains measurement enclosure.
