8.5.3 Three-Phase System Use
8.5.3.1 Output Wiring Configurations
The output of a 3-Phase system can be connected for three-phase, four wire (Wye
configuration) loads or for three-phase, five wire (Delta configuration).
3-PHASE CONFIGURATION NOTES:
• Phasing: The Master unit is always phase A, Slave1 is always phase B and Slave2 is
always phase C.
• Connect Mode: Connect Mode covers both Wye and Delta types.
• The output voltage of phase B and C will be set to the same settings as that for
phase A (Master). Automatically if the Voltage Mode is set to COM (Coupled). If the
Voltage Mode is set to Multi, phase B and C output voltage can be set individually
(Uncoupled).
• The output frequency of phase B and C is always set to the same frequency as phase
A. The phase difference between phase A and B is always 120° and between phase A
and C is always 240°.
• Waveforms groups A and B can only be switched AFTER the system output is OFF.
For a 3-Phase configuration, there is one Master and two Slave so there are always 3 units.
The Master unit must be set to Mode = Master, Master Type = 3-Phase as shown in the
screen below.
