Three-Phase PDU Input and Outlet Group Relationship

Figure 6  Three-Phase PDU Input and Outlet Group Relationship

image:Figure showing the relationship between the metering unit inputs and the 3-phase PDU outlet groups.

Note -  For three-phase, low-voltage PDUs, each metering unit phase reports current from two outlet groups. Input phase 1 reports a combination of current from outlet groups 0 and 2 (3 and 5, or 6 and 8, depending on which input). Input phase 2 reports a combination of current from outlet groups 1 and 0 (4 and 3, or 7 and 6, depending on which input). Input phase 3 reports a combination of current from outlet groups 2 and 1 (5 and 4, or 8 and 7, depending on which input).
