2. Warnings

The electrical panel must be used only for its intended purpose. Any other application is improper and dangerous. In case of fire, avoid water jets and use appropriate extinguishing agents (powder, foam, carbon dioxide). Install the device away from heat sources in a dry, sheltered location, respecting the declared IP protection rating. Install a safety device to protect the power line, in compliance with current electrical standards. Before any intervention on the electrical panel or system, disconnect the power supply. Do not disassemble parts of the panel without authorization; any tampering or unauthorized modification will void the warranty. Installation and maintenance operations must be performed by a qualified technician aware of safety regulations. Ensure connection to an efficient grounding system. After electrical connection, verify the panel settings as the electric pump may start automatically. The manufacturer is not liable for: incorrect installation; use by untrained personnel; lack of maintenance; use of non-original spare parts; unauthorized modifications; non-compliance with instructions.

6. Quick Start Guide

6.1 Prerequisites

• Smartphone for Wi-Fi configuration.
• DC power supply with output voltage between 11-28 VDC.
• Wi-Fi module with LTE connection (if no local Wi-Fi network is available) and 2.4G frequency.
• Disable any firewall restrictions.

6.2 Gateway Configuration

Wi-Fi Connection

1. Upon first power-up, the device creates a Wi-Fi network named "IOT CAPTIVE PORTAL".
2. Connect to the IOT CAPTIVE PORTAL network. The first connection may require a password: enter 12345678.
3. Open a browser and enter IP 192.168.4.1.
4. The user connecting to this network will be automatically redirected to a web page for network configuration.
5. Select the name of the Wi-Fi network the device should use, enter the Wi-Fi password, and press "Connect". The device will attempt to connect to the selected network and then to the cloud platform. If the connection fails, the configuration Wi-Fi network ("IOT CAPTIVE PORTAL") will be regenerated.

Once connected to the internet (via Ethernet or Wi-Fi), the device will start communicating information to the "IoT Platform".
