Three-Phase PDU Module and Outlet Group Relationship

Figure 4  Three-Phase PDU Metering Unit Module and Outlet Group Relationship

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

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