The PDU models with 9 C19 outlets on the front have phase one connected to the first three (3) outlets, outlet
group one. Phase 2 is connected to the next three (3) outlets, outlet group two. Phase 3 is connected to the
last 3 outlets, outlet group three (see the following illustration).

Some models have 3 outlets on the rear of the PDU. These outlets are not monitored or switched. Each
outlet is connected to a different phase.
To balance loads on the PDU, do not connect loads so that there is more load on one group of outlets than
others. For example, if there are three loads on a 9-outlet PDU, do not use outlets 1, 2, or 3; use outlets 1, 4,
and 7.
If there are three loads on a 12-outlet PDU, use outlets 1, 5, and 9. If there are more then 3 loads, distribute
them across the three output groups.
