1.2. Features Smart and efficient charging The EVNET belongs to a class of EVSE called smart chargers, because its entire functionality can be controlled remotely and automatically. This is enabled by the OCPP 1.6J protocol support embedded in the charger. This is a universally accepted control protocol for charging stations, meaning that any OCPP-based server can talk to, control, and remotely update the EVNET, independent of service provider and other factors. -
Page 7: Device Specifications
Additionally, EVNET socketed chargers feature an electromechanical lock, which secures the Type 2 connector while the socket is energized and prevents the plug from being accidentally disconnected under power. A tamper sensor, embedded in the device, is used to detect unauthorized disassembly. The charger utilizes both sound and light signaling to report its state and possible faults, enabling the quick and safe detection of problems. -

Page 11: Electrical Wiring And Breaker Requirements
2.1.3. Electrical wiring and breaker requirements 2.1.3.1. Calculating circuit voltage drop and sizing circuit wiring and breaker In order for the EVNET to provide full charging power, it must be supplied through a dedicated circuit capable of handling the full 32A of current with less that 10 VAC voltage drop. The circuit’s nominal rating should be no less than 40A. - Page 12 Table 2 can be used to determine the approximate voltage drop at peak currents. The installed length is the running distance from the source panel to the EVCP (the table takes into account resistance in both legs of the circuit). Voltage drop in copper conductor at 40A, VAC Area, mm Installed length, m...
- Page 13 The nomograph below can be used to calculate the circuit voltage losses at peak current. For a given test load, a line can be drawn from the origin to the corresponding value on the upper horizontal axis. Then, the measured voltage drop can be matched to the corresponding peak current drop by reading out the left vertical axis.

2.2. Installation: Mechanical The main screws fastening the main body of the EVNET are located in the four corners of the charger body, and may be directly accessed (the felt protecting pads may have to be removed). The EVNET is intended for wall-mounting via four holes in the enclosure lower body, as seen in Fig 6. - Page 15 2.2.1.

Overall system wiring diagram Fig 9 EVNET installation diagram, overall Hint: Due to the universal availability of CAT5 UTP cable, it is advisable to use it as a combined cable for the Ethernet and CT clamp connections, avoiding a second run of signal wires. Two twisted pairs are used for the CT clamp connection and two for the Ethernet Tx and Rx lines. - Page 17 2.3.2.1. Socketed model The connection terminal is located on the EVNET body. One side is connected to the EVNET board via short conductors that have been prepared at the factory. If the connecting cables are detached from the main assembly, the following diagram illustrates their connection.

Page 19: Accessing The Web Client And Configuration
2.5.1. Accessing the web client and configuration The EVNET has a backend that is accessible via a web interface. The web client can be accessed from any HTML browser on a Wi-Fi enabled device, such as a smartphone, tablet, or laptop. On startup, the EVNET broadcasts its name and serial number as a Wi-Fi network. - Page 20 This will afford the main page of the EVNET web client - Device Status and Control – and a navigation bar on the left: All pages feature “Restart” and “Refresh” buttons to power cycle “Device status” lists all the device or request the the important conditions page again of the charger, including...

- Page 22 Once the admin credentials have been entered and the login verified, the navigation bar shows additional items, as shown on the left. When configuring the EVNET for the first time, the following settings must be made: Setting the virtual fuse (based of CT clamp input) Configuration of RFID access cards Configuration of the backend interface for smart charging and app access features, such as scheduled...
- Page 23 Setting the virtual fuse limit is done in the “Configuration of External Devices” tab, which can also be used to configure other devices on the RS-485 bus, used for the CT clamp communication. To configure RFID access cards, open the “NFC Configuration” tab. Here, the EVNET can be set into a “Learn”...

2.6. Installation: Troubleshooting 2.6.1. Verifying charger functionality: At power on, the EVNET has default settings and configuration, which allow it to work as a basic charger in the offline state. It is possible to verify its basic functionality by plugging in an EV and observing that the charger starts a charging session. -
Page 27: Hardware Reset
2.6.3. Hardware reset The configurator may determine that a factory reset of the device is necessary. A factory reset returns the device to its original software at the point of manufacture. Any firmware updates are not rolled back. The hardware reset button is located on the main board of the EVNET, as shown in Fig 8. To reset the device, it must be disconnected from mains power. -

- Page 30 RTM Errors RTM errors are generated byEVNET when an error occurs and the charging is stopped. They can be found as “RTM err code” in the Diagnostics tab of the web client. Code Name Description Detailed Description This error code is sent when the AC RCD protection is EVSE_FAULT_ triggered.
- Page 31 This error code is sent when the temperature of the charging station reaches more than 79 degrees. At this EVSE_FAULT_ Overheating 0x0800 point the charging station will stop charging at all. This TEMPERATURE error fault is cleared when the charging station is power cycled or through the web client.
