Three-phase four-wire active electronic energy meters are developed by our company using microelectronics technology to measure electrical energy. They are equipped with imported dedicated large-scale integrated circuits and utilize advanced digital sampling processing technology and techniques. These meters fully comply with the technical requirements of the GB/T17215.321-2008 national standard and the IEC6205-21 international standard for Class 1 three-phase active energy meters. They feature high reliability, compact size, lightweight, attractive appearance, and advanced technology. They also offer excellent resistance to electromagnetic interference, low self-consumption for energy-saving, high precision, high overload capacity, high stability, anti-theft protection, and long service life. These meters are suitable for measuring three-phase AC active electrical energy with a rated frequency of 50Hz or 60Hz. They are designed for fixed indoor installation and are suitable for environments with temperatures not exceeding -25 to 55°C.Relative humidity should not exceed 95%, and the air should be free of corrosive gases, as well as dust, mold, salt spray, condensation, insects, and other influencing factors.

Installation Precautions
Installation of a three-phase four-wire active electronic energy meter requires an experienced electrician or professional, and it is necessary to read this manual thoroughly.
2. The electricity meter should be installed in a well-ventilated and dry indoor location, using 35mm DIN standard track mounting. The base of the electricity meter should be securely fastened to a strong, fire-resistant, and vibration-resistant wall.
3. In areas with dirt or potential damage to the installation, the electric meter should be installed inside a protective cabinet.
4. When installing wiring, please follow the wiring diagram on the right side of the electric meter or the corresponding diagram in this manual to accommodate multi-strand copper wire and prevent poor contact from causing issues.
