In the purchase of electronic single-phase multi rate watt hour meter (LEM041 Series DIN Rail Three Phase Multi-rate Electronic Energy Meter), it should be equipped with the installation instructions. You can install the meter according to the instructions, or search the company's name in the Baidu library, there will be a variety of types of meter installation instructions. Here, we talk about the attention of the meter installation.
1. The installation of wiring should be in accordance with the electric energy meter side wiring diagram wiring, preferably with copper wire access.
For direct access type electric energy meter wiring should pay attention to the direction of the line and the outlet, and tighten the screws to avoid the poor contact caused by the work of the energy meter is not normal;
Pay attention to the polarity of the secondary current transformer when the current transformer is connected with the electric energy meter.
2. The load capacity of the electric energy meter in 0.05Ib ~ Imax (direct access) or 0.02Ib ~ Imax (access through the current transformer), between the capacity of the load range, will make the energy metering is not allowed or damaged.
3. Direct access to the electric energy meter, the number of electrical energy that is the actual electricity consumption; when the electric energy meter with current transformer access, the number of readings must be multiplied by the number of current transformer is the actual power consumption.
The installation of electronic single-phase multi rate watt hour meter must pay attention to these, it is best to install electronic single-phase multi rate watt hour meter by professionals .
