Characteristics And Installation and Wiring Method of Single-Phase Electronic Prepaid Electric Energy Meter

The single-phase electronic prepaid electric energy meter adopts an advanced electric energy metering unit, high-performance CPU, liquid crystal display, and new smart electric energy meter manufactured by SMT advanced technology. The electric meter has an infrared communication port, GPRS module, and RS485 communication port, which can read various information on the electric energy meter. The single-phase electronic prepaid electric energy meter is mainly used in the measurement of single-phase AC electric energy with a rated voltage of 220V and a rated frequency of 50HZ. It has the advantages of stability and reliability, high measurement accuracy, and convenient installation. It is suitable for remote centralized meter reading systems and is an ideal product for upgrading electric energy meters.

Single-phase electronic prepaid electric energy meter installation and wiring method.

1. Before leaving the factory, the electric energy meter is tested and qualified, and sealed with lead. After getting the new meter for inspection, it can be installed.

2. The electric energy meter can be installed indoors or outdoors according to the actual situation of the customer, and its floor needs to be fixed on the refractory wall. The recommended installation height is generally about 1.8 meters, which is convenient for reading the meter data, and there is no corrosive gas in the environment.

3. The electric energy meter needs to be wired according to the wiring diagram on the junction box, and it is best to use copper wire for connection.

4. The installation and wiring method is as follows: 1 is connected to the phase line-in, 2 is connected to the phase line out (connected to the electricity end), 3 is connected to the neutral line in, and 4 is connected to the neutral line out (the electricity end).
