Overview
PDU monitoring unit
This connection provides the input power for the PDU monitoring unit. The power is supplied by the monitoring unit circuit breaker on the front of the PDU. If the panel is on, and the monitoring unit circuit breaker is closed, the monitoring unit is powered.
Connects to sensors monitoring values such as, voltage, current, and power.
Digital input sensing for monitoring such as, circuit breaker status, transformer temperature, fans, etc.
The Display port
The Power LED indicates wether the monitoring unit is receiving power.
Use the Console port
EPO DIP switches configure the EPO input for the type of EPO switch that is
When the EPO Arm/Test rocker is in the Test position, engaging the EPO switch will not cause the load to be powered off. When the rocker is in the Armed position, engaging the EPO switch will cause the PDU’s Main Input switch to be switched OFF. See “How to Test the EPO Switch” on page 54 for more information on testing the EPO switch.
The EPO Armed LED is green when the rocker is in the Armed position. The LED is dark when the rocker is in the Test position.
The EPO Tripped LED is red when the EPO switch is engaged (the EPO button is pressed), regardless of the state of the EPO Arm/Test rocker.

The Reset button resets the network processor; it does not reset the PDU or the PDU monitoring unit.
Connect to the InfraStruXure Manager through the network port.
Not used on this model PDU.
The optional User/EPO Contacts port is connected to wire harnesses that connect to the User Connection Plate in the roof (or floor) of the PDU. The port allows for relay outputs (4), input contacts (4), and an EPO input (1). See “Contacts Screen” on page 18 and “How to Test the EPO Switch” on page 54 for more information.
| The branch current monitoring boards connect to the Branch Current Monitor ports |
| ports are on the top side of the PDU monitoring unit, and are labeled on the face of the unit. Each port |
| corresponds to a section of circuit breakers on the PDU distribution circuit breaker panel: |
Note | upper left=[01..41]; upper right=[02..42]; lower left=[43..83]; lower right=[44..84]. |
