To install the ePowerMeter 2 PowerMeter, it is important to follow the instructions provided in the user manual. Here is a step-by-step guide:
1. Ensure that you are a qualified professional electrician before attempting the installation. Installing the PowerMeter without proper qualifications can be dangerous.
2. The ePowerMeter 2 PowerMeter is designed to work with Dynamic Power Management (DPM), which allows you to recharge your electric vehicle using available power at home. It modulates the charging power to avoid blackouts. If you do not require DPM, the installation of a dedicated PowerMeter is not necessary, but blackout prevention is not guaranteed.
3. Refer to local regulations, user manuals, and wallbox installer manuals for more information about the installation process. These documents can be found on the website: www.esolutions.free2move.com/document...
4. Only PowerMeters provided by Free2move eSolutions S.p.A. are compatible. The installation must be performed by qualified personnel in accordance with local regulations.
5. Follow the PowerMeter manual included in the package during the installation process.
6. Place the PowerMeter after the main utility meter and before the split power.
7. For the electrical connection, refer to the dedicated installation manual included in the PowerMeter package. The instructions will vary depending on whether you have a three-phase or single-phase connection.
8. Feed the Modbus communication cables through the wallbox box sheath. It is recommended to use STP class 5E cables with a 0.5 mm2 section.
9. Connect the communication cables from the PowerMeter to the Wallbox in the following order: GND to SC, RS485-B to B, RS485-A to A. These connections should be made on the wallbox RS485 output port "CN12".
10. When powering up the PowerMeter for the first time, press and hold the touchscreen button until the display text blinks. Then select the SETTING command and press and hold again to enter the menu.
11. In the menu, select the COMMUNICATION command (or COMM for single-phase meter) and press and hold to enter the menu.
12. Set the following parameters:
- Device address: 001
- Bits per second (baud): 38400 bit/s
- Parity: Even
- Stop bit: 1
- Connection mode: 3L+N "Arithmetic" (required for three-phase PowerMeter only)
13. Press and hold ESC to go back. For three-phase PowerMeter only, select INSTALLATION, press and hold to enter the menu, and set the Connection mode to 3L+N "Arithmetic".
14. It is crucial to complete the above steps correctly before powering up the PowerMeter to avoid damage to persons and property.
