Before any installation or maintenance, you read and understand the XNX Safety Manual (document number 1998‑0808). Key safety precautions include:

You have successfully moved from unboxing to operational status. The Xnx Universal Transmitter is now monitoring your environment, sending clean 4-20mA data to your controller, and keeping your facility safe. Keep this in your maintenance binder—specifically the calibration and troubleshooting sections. Xnx Universal Transmitter Quick Start Guide
