Tips: Notes for installation and use of energy meter

1. The installation site of the energy meter should be dry, convenient for reading, free of any dust, heat source, mechanical vibration or magnetic interference(The lead with a distance of over 100A should not be smaller than 400mm). The distance to the heat distribution pipeline should not be smaller than 0.5m. If it is installed outdoor, the rain-proof measures should be taken.
2. The power circuits of different power prices should be installed with the meters separately. The power circuits of the same power price should be installed with the meter in a combined manner.
3. The energy meter should be installed vertically. The front, rear, left and right inclination are not more than 2°, especially the mechanical energy meter. When the inclination is 5°, it will cause 10% measurement error. The center of the energy meter is generally 1.5~1.8m away from the ground. When it is installed in a complete set of switchgear cabinet, the distance from the ground shall not be less than 0.7m, and the distance between the centers of the two meters shall not be less than 200mm. The incoming line is connected to the power while the outlet is connected to the load. The three-phase energy meter should be connected to the circuit in the positive phase sequence and wired according to the wiring diagram on the terminal cover.
4. The energy meter equipped with the transformer, the same-name terminals of the secondary winding of the transformer should not be connected wrongly, that is, the L1 and K1 of the input end of the power phase line and the L2 and K2 of the output end should be corresponding, and should not be connected reversely, otherwise, the intelligent energy meter might rotate in a reversed direction, not rotate or have inaccurate measurement. The switch and fuse protector should be connected to the load side of the energy meter.
