AC Power PDUs
Each PDU is factory-wired to distribute the phases to its receptacles.
Caution. If you are installing Integrity NonStop NS-series enclosures in a rack, balance the
current load among the three phases. Using only one of the available three phases, especially
for larger systems, can cause unbalanced loading and might violate applicable electrical
codes. Connecting the two power plugs from an enclosure to the same phase will cause failure
of the hardware if that phase fails.
