The meter ports are shown as follows, where the CT port is used to connect the CT to
detect the current, and L1, L2, L3, N ports are used to detect the voltage.
If there is only L1(to terminal 2) and the neutral conductor (to terminal 10), then
the three-phase Smart Energy Meter can be used as a single-phase Smart Energy
Meter.
