# Power supply

TX MODBUS: power supply

The MODBUS TX accepts a wide DC voltage range.

## Technical specifications

* Voltage range: 7.5 to 24 VDC.
* Typical consumption: 12V / 1A.
* Polarity: Wire <mark style="color:$danger;">**Red**</mark> (+) / Wire **Black** (-).

## Connection options

The installer has two methods for powering the device:

1. **Pre-installed wiring** : The product comes with a cable exiting through the cable gland. You can connect directly to this cable, following the color code (Red = Positive, Black = Ground/Negative).
2. **Custom wiring** : For a custom installation, it is possible to remove the original wiring. Unscrew the cable gland, remove the existing wires, and run your own power cable for a direct connection to the internal terminal blocks on the circuit board.

## Recommended accessory

For optimal reliability and simplified installation, Enless Wireless offers a dedicated mains power supply:

* Reference: **POWER 1000-002**
* Specifications: Regulated 12V power supply.

{% hint style="warning" %}
**Safety** : Before any work on the internal terminal block or modification of the wiring, make sure that the power source is**powered off**. Reversing the polarity can damage the receiver's electronic components.
{% endhint %}

{% hint style="danger" %}
To avoid any problems, please maintain 1A 12V at the TX Modbus power terminal block

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enless.gitbook.io/centre-aide/guides-installation/documentation-en/sensors/editor-21/installation/power-supply.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
