Table 5-12 Voltage Harmonic Measurements
Notes:
1)
When the Wiring Mode is 3P3W or 1P2W L-L, the phase A/B/C Voltage THD/TOHD/TEHD/HDxx mean phase AB/BC/CA
Voltage THD/TOHD/TEHD/HDxx.
2)
When the Wiring Mode is 1P2W L-N or 1P2W L-L, the L2 and L3 phase voltages THD/TOHD/TEHD/HDxx have no meaning,
and their registers are reserved. When the Wiring Mode is 1P3W L-N, the L3 phase voltages THD/TOHD/TEHD/HDxx have
no meaning, and their registers are reserved.
