1 Voltage range for the maintenance switch is 200-240 V ac.
Each PDU is factory wired to distribute the phases to its receptacles. Refer to “Supported PDUs
and Power Offerings” (page 27) and to “Balancing Power Distribution” (page 30).
Factory-installed enclosures are connected to the PDUs for a balanced load among the phases.
Balancing Power Distribution
If you are installing the Neoview platform in a rack, balance the current load among the three
phases. Using only one of the available three phases can cause unbalanced loading and might
violate applicable electrical codes. The previous illustration shows the balanced power distribution
for one power rail. You must rotate the phase for each PDU so that the customer does not have
the same power phase on an enclosure.
The previous illustration shows the balanced power distribution for one power rail. You must
also balance the other power rail and rotate each PDU phase to prevent having the same power
phase on an enclosure.
