The meter has a friendly man-machine interface. Electric wiring diagram and wiring diagram as shown in the concentrator:
Be careful：
Voltage input：When direct input, the rated input voltage input voltage should be not higher than the meter (400V), you should consider the use of voltage transformer (PT). 1A fuses must be installed at the voltage input.
Current input: Standard rated current is 5A, when the input current is more than 5A, you must use the external current transformer (CT).
To ensure that the input voltage, input current corresponding to the same order, the line and the direction of the line is consistent, otherwise there will be a number of measurements and symbol error.
The electric meter input connection mode according to the number of the current mutual inductor, in the case of external 2 current transformers, select three-phase three wire connection mode. In the case of external 3 current transformers, select the three-phase four wire connection mode.
