4.1. Power supply

The meter adopts external power supply mode, without internal direct power supply. The power supply voltage range is 95 ~ 265VAC / 110 ~ 260VDC, 45 ~ 60Hz,  and the maximum power consumption is 3.5VA.
  • Do not connect the meter with the cable live.
  • Before connecting the power supply, make sure that the power supply voltage is within the required range, otherwise the meter can not work normally.

4.2. Voltage and current input

The meter supports two wiring modes, three-phase four wire (3P4W) and three-phase three-phase (3P3W)
  • The actual wiring mode of the meter must be consistent with that of the internal configuration of the meter.
  • Three phase four wire requires three current sensors.
  • Two or three current sensors are required for three-phase three wire system. The use of two current sensors does not affect the measurement of power and electric energy, but the current of phase B cannot be measured. Three current sensors can be used to measure phase B current.
  • The phase sequence of voltage and current must follow the phase sequence of ABC, otherwise the meter will display the phase sequence error of voltage and current.
When using the current sensor, the direction of the current arrow on the sensor must be consistent with the actual current flow direction, that is, the current arrow of the sensor points to the load end
