Wiring Diagrams
To avoid electric shock, do not change the wiring when the power is on.
Install a breaker switch on the power cord for the meter because there is no power switch on the power
meter.
When the measured voltage is higher than the rated specification for the device, it is necessary to use an
external potential transformer (PT).
When the measured current is higher than the rated specification for the device, it is necessary to use an
external current transformer (CT).
