Installation Overview
•
The input power cord must be securely attached
and it should be connected to the AC mains by
hardwiring or through the use of a nonresidential, industrial-style plug that maintains
positive earth connection.
•
If the total system leakage current through the
ground conductor exceeds five percent of the
input current per line under normal operating
conditions, the system loads should be divided
among multiple power connections.
The PDU can be mounted in the rack so that the breakers are
at the top of the unit or on the bottom of the unit to
accommodate multiple configuration options.
The PDU can be mounted in the rack the following ways:
•
Standard mount ("Installing the HP Power Distribution
Unit with Power Monitoring in the Standard Mount
Position" on page 3)
NOTE: This product arrives with the mounting brackets
already installed for a standard right side, breakers at
the bottom mount.

Important Safety Information
-or-
Before installing this product, read the Important Safety
Information guide provided.
One dual PDU North America and Japan Model
WARNING: To reduce the risk of personal
injury from electric shock, do not remove the cover.
There are no field-serviceable or user-serviceable
components inside.
WARNING: A risk of personal injury from
electric shock and hazardous energy levels exists.
The installation of options and routine maintenance
and service of this product must be performed by
individuals who are knowledgeable about the
procedures, precautions, and hazards associated
with AC power products.
Follow these safety precautions when connecting multiple
pieces of information technology equipment to power
products.
WARNING: To reduce the risk of personal
injury from high-leakage current, verify earth
connection before connecting the power supply.
The summation of input power for multiple pieces of
information technology equipment through the use
of power products can result in high-leakage
currents.
If the total system leakage current for a system of
components exceeds 3.5 mA:
•
The use of a detachable input power cord is
prohibited.

Installing the HP Power
Distribution Unit with Power
Monitoring in the Standard Mount
Position
2. Insert three screws, securing the PDU to the rack frame.
1. Slide the tabs on the PDU mounting bracket into the rack
frame.
3. Attach the device power cords to the PDU.
4. (Optional) Wrap a power cord retention band around each
power cord, and insert the end of the power cord retention
band into the appropriate slot on the PDU mounting
bracket.
NOTE: Firmly pull the power cord retention bands tight,
paying special attention not to sever them.
5. Plug the PDU power cords into the appropriate power
outlets.
NOTE: Be sure that the circuit breakers are in the off
position before attaching the power cords to the power
outlets.
6. Power on the PDU breakers.
Installing the HP Power
Distribution Unit with Power
Monitoring in an Alternative
Mount Position
1. Remove the five screws securing each mounting bracket
to the PDU.
NOTE: For single PDUs, be sure that the five screws,
on the side of the unit without a mounting bracket, are
also removed.
2. Rotate the PDU 180 degrees, so that the power cords are
now at the top of the rack.
3. Reattach each mounting bracket to the PDU using the
same five screws from step 1.
NOTE: For single PDUs, be sure that the five screws
from step 1, are inserted into the side of the unit without
a mounting bracket.
4. Continue to "Installing the HP Power Distribution Unit
with Power Monitoring in the Standard Mount Position
(on page 3)."
Checking the Circuit Breakers
If power to a device is interrupted, check the circuit breakers
and reset them if necessary. If power is still not restored,
contact your HP authorized service representative.
Front Panel Display Overview
Callout
Description
The PDU front panel has a two-digit, LED display that shows
the current in each circuit breaker, a scroll button to scroll
through values, and six LEDs, which indicate current
overloads and voltage out of range conditions.

Scroll button
11
Seven segment LED numeric display
During the power-on process or after a power restart, all of
the indicators on the front panel display are illuminated for a
minimum of two seconds to verify operation (the bicolor
LEDs are switched every second during this verification
process).
NOTE: Each load segment is associated with one
circuit breaker. For NA/JPN three-phase models, each
load segment is fed by one pair of phase conductors.
For International three-phase models; each load
segment is fed by one phase conductor and the neutral
conductor.
Front Panel Display Components
Inverting the Numerical Display
If you are mounting the PDU in the rack with the breakers at
the top, press and hold the scroll button for over three seconds
to invert the seven-segment display 180 degrees.
HP Power Distribution Unit with Power
Monitoring Normal Operating Conditions
The dual seven-segment display shows the current in the load
segment selected. For current values above one Amp, the
value is displayed without a decimal point. For example, one
Amp is displayed using only the right-most digit.
During normal conditions, all load segment LEDs are
illuminated green. The illuminated green LED corresponding
to the load segment currently being displayed flashes. If an
alarm condition exists, the load LED for that load segment is
not illuminated green, but rather amber or red.
After five minutes of inactivity, if no alarms are present, the
front panel display begins to automatically scroll through the
load segments. Inactivity is defined as no user inputs—for
example, not pushing the scroll button, for five minutes.
When the unit is automatically scrolling through each load
segment—the current displays for three seconds before
switching to the next segment. When the scroll button is
pushed during the automatic function, the automatic function
is terminated until the five-minute criteria for automatic
scrolling is met again.

If an overload condition exists, the corresponding
load segment LED with the alarm condition is
illuminated red, while the green load segment LED
for that particular load segment is not illuminated.
−
Load Warning—Current greater than 80%, but less
than 102%, of allowed maximum per load segment
(amber alarm LED)
If a load warning condition exists, the corresponding
load segment LED with the alarm condition is
illuminated amber, while the green load segment
LED for that particular load segment is not
illuminated.
•
Voltage Out of Range
−
Overvoltage of 10% to 20% (amber alarm LED),
overvoltage of greater than 20% (red alarm LED)
−
Undervoltage of 10% to 20% (amber alarm LED),
undervoltage of more than 20% (red alarm LED)
When an alarm condition occurs, the front panel display
automatically changes to show the circuit with the alarm
condition regardless of the present display setting. The
automatic scrolling function is disabled when an alarm
condition exists.
If an alarm condition displays and you scroll to display
another circuit that does not have an alarm condition present,
the circuit without an alarm is displayed for 10 seconds and
then switches back to the alarmed circuit. If an alarm
condition displays and you scroll to another circuit with an
alarm condition, the display remains on the last circuit
selected with an alarm until the alarm condition clears or you
scroll to a different circuit.
If multiple circuits have alarm conditions at the same time,
the last circuit to activate an alarm is displayed.
