Customizing and Updating the PDU
150kW InfraStruXure PDU—Operation and Configuration 53
4. At the front of the PDU, connect the power cord’s individual wires:
a. If you have branch current monitoring installed, route the phase conductor through a current
sensor. If it is a three-phase cable, route the L1, L2, and L3 wires through a current sensor.
b. Connect the L1, L2, and L3 wires to the circuit breaker(s). The illustration below shows
single pole breakers; however, you can also connect three-pole breakers.
c. Connect the neutral wire to the closest open termination point on the Neutral Bar (N).
d. Connect the ground wire to the closest open termination point on the Ground Bar (G).

Caution
You can configure your InfraStruXure system through the InfraStruXure Build-Out Tool
to use 3, 20A, single-pole breakers to feed multi-circuit power cables supplying power to
L-N loads. However, one 3-pole, 20A circuit breaker must be used with any power cable
and Rack PDU that feeds L-L loads (NEC, NFPA 70).
