Important safety information

Enterprise Basic PDU.

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).

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.

• 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
output cannot exceed the total output rating marked on the PDU.

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.
