**Purpose of grounding**

* Functional grounding
* Improve EMC: provides a low-impedance return path for high-frequency noise, effectively reducing electromagnetic interference (EMI).
* Ensure signal integrity: maintains a stable system reference potential, preventing data errors or system restarts caused by potential fluctuations during use.
* ESD discharge: routes induced charges on the chassis to ground, protecting sensitive internal electronics (e.g., GPU, core modules) from electrostatic disturbance.

**Cable Specifications**

* High-frequency considerations: use a braided grounding strap or a large cross-section multi-stranded copper cable to reduce impedance caused by the skin effect at high frequencies.
* Shortest-path principle: the cable should be as short and wide as possible to avoid forming inductance.
* Routing separation: functional grounding should be kept away from power wiring to avoid coupling noise into the system.

**Step-by-step grounding procedure**

<figure><img src="/files/n4FEEtOmtIyVnrYBcSzW" alt=""><figcaption></figcaption></figure>

* Locate the dedicated grounding point on the Orin Box marked with the FE (Functional Earth) symbol.
* Prepare a low-impedance braided grounding strap or multi-stranded copper cable, and crimp high-quality O-type terminals on both ends.
* Clean the contact surface, ensuring the metal is free of paint or oxide. Use a star washer for broad-band contact with the metal chassis.
* Fasten the terminal at the designated location, ensuring good electrical conductivity at the joint.
* Connect the other end to the system’s signal reference ground bus, or to the cabinet’s dedicated Clean Earth.
* Verify with a spectrum analyzer or a low-impedance tester. At high frequencies, the impedance of the grounding path must be very low.
* Isolation check: ensure the functional ground path does not introduce external mains-frequency noise due to poorly designed ground loops.
* Confirm that the shields of all sensors are properly bonded to this grounding point for best immunity.

# 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 dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.engenius.ai/home-engenius-qsg-library/engenius-edge-ai-computer/orin-box-series.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
