Overview
This document provides installation instructions for qualified personnel for installing a Hewlett Packard
Enterprise Basic PDU.
Safety and regulatory compliance
For important safety, environmental, and regulatory information, see Safety and Compliance Information
for Server, Storage, Power, Networking, and Rack Products, available at the Hewlett Packard Enterprise
website (http://www.hpe.com/support/Safety-Compliance-EnterpriseProducts).
Important safety information
Before installation, read the Important Safety Information that ships with the product you are connecting.
This document is also available on the Hewlett-Packard Enterprise website
(http://www.hpe.com/support/importantsafetyinformation).
This PDU is intended only for ITE loads with linear/PFC input current. If non-linear loads are connected,
the nameplate current rating of the PDU must be reduced by a factor of 0.8.
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 hardware components to power sources.
WARNING: To reduce the risk of fire, electric shock and damage to the equipment:
•Connect only to a circuit providing branch circuit overcurrent protection of appropriate
current rating.
•
Connect the input power cord into a grounded (earthed) electrical outlet that is located near
the equipment and is easily accessible.
•Be sure all circuit breakers are in the off position before connecting input power.
•Be sure that the load products connected to the HPE PDU are adjusted for, or otherwise
capable of operation from the same line voltage supplying the PDU. Failure to verify the
voltage can lead to severe equipment damage.
•Do not overload the PDU. The total input current rating o
f all equipment connected to each
output cannot exceed the total output rating marked on the PDU.
•
Use only the hardware provided to install the PDU.

Before you begin 5
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.
•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 non-residential, industrial-style plug that
maintains positive earth connection.
•If the total system leakage current through the ground conductor exceeds 5% of the input
current per line under normal operating conditions, the system loads should be divided
among multiple power connections.
Required tools
The following tools are required for installation:
•Phillips screwdriver
•Torx screwdriver
Additional requirements
If your facility or configuration requires an L5-20R plug, you must obtain a third-party L5-20R to NEMA
5-20P adapter before installing or connecting the H5M54A 1.9kVA 120V Basic PDU.

Recommended hardware configurations 6
Recommended hardware configurations
Configurations
The PDU is installed in a rack in the following configurations:
•A single PDU configuration, with the outlets facing the center of the rack
•A single PDU configuration, with the outlets facing the rear of the rack

Recommended hardware configurations 7
•A double PDU configuration, with the outlets facing the center of the rack
•An inverted PDU, with the input power cable exiting the top of the rack

Recommended hardware configurations 8
•1U and 0U configurations

Hardware installation
Installing the PDU
NOTE: If you install the PDU facing the front of the rack or on the opposite side of the rack
from the following images, install the components on the opposite side of the PDU shown in the
images.
1. Align and install the power cord retention bracket with the screw holes marked "C."
2. Align and install the mounting pins with the screw holes marked "M."

3. If installing the PDU inverted, install a mounting pin on the bottom of the PDU.
4. If needed, install the input power cable retention band.

Hardware installation 11
5. If needed, insert and secure the power cable.
6. Install the PDU and ensure the mounting pins are engaged with the rack.
CAUTION:
When moving a rack with installed components, always use the shipping bracket
to secure the PDU.

Hardware installation 12
7. If the PDU is not inverted, install the shipping bracket above the PDU.
8. If the PDU is installed above 39U, flip the PDU shipping bracket to allow space for the rack shipping
bracket.

9. If the PDU is inverted, install the shipping bracket over the mounting pin below the PDU.
Installing 1U and 0U PDUs
1. Attach the power cord retention bracket.
2. Attach the appropriate mounting brackets. Each bracket only requires two screws per side for this
product.
