Note
Where the current is measured may have some effect on the measurement results. To mitigate
this effect, consider where the voltage and current are measured. For a signal with high
voltage and low current, the voltage channel should be connected to the side that is closest to
the source, the current channel should be connected in series (or the sensor should be placed)
to the side that is closest to the load (as shown in the wiring diagrams). For a signal with low
voltage and high current, connect the voltage channel to the side that is closest to the load,
and connect the current channel in series (or the sensor should be placed) to the side that is
closest to the source. Please refer to the appendix

Wiring Group
When you select a specific wiring selection, use a combination of 2 or more channels, which is called a
wiring group.
For example, when the wiring selection of channel 1 is set to 3P3W2M, channel 1 and channel 2 form
a wiring group.
