1. Firmly push the red pushbutton until it locks into place. The switch latches into
the activated state (see Figure 6-11).
The PDU main input breaker trips, and the PDU turns off immediately, without
asking for verification. If an upstream feeder breaker is connected to the REPO,
the feeder breaker also trips.
