Signal Wiring Diagrams
Note
：
(a) External wiring mode should be the same as internal wiring mode of
meter. Otherwise, measured information of meter will be not correct (Please
refer to 5.5 for detailed setting method).
(b) Meter measures AC voltage and current signals. Please do not connect
DC signals to input terminals of meter.
(c) Voltage input: The external PT should be applied when the input voltage
exceeds the rated value. Accuracy of external PT should be equal to or better
than measurement accuracy of meter. For easy maintenance, it is suggested
to use the terminal blocks.
