SAVE THESE INSTRUCTIONS

This safety sheet contains important safety instructions. Read all safety, installation and operating
instructions before installing the Emerson Network Power MPH2 rack power distribution unit (PDU).
Adhere to all warnings on the unit and in this safety sheet. Follow all operating and user instructions.

• The MPH2 rack PDU is designed for information technology equipment. The MPH2 rack PDU is
not intended for use with life support or other designated critical devices. If uncertain about its
intended application, consult your local dealer or Emerson representative.

• Maximum load must not exceed the rating shown on the MPH2 rack PDU nameplate.

• The rated line voltage must not exceed 240VAC for connection to AC power distribution systems
with an isolated or high-impedance ground.

• Operate the MPH2 rack PDU in an indoor environment only in an ambient temperature range of
32°F to 140°F (0°C to 60°C) for 24A or less input models and 32°F to 122°F (0°C to 50°C) for 40A
and 48A input models.

• Install the MPH2 rack PDU in a clean environment, free of conductive contaminants, moisture,
flammable liquids, gases and corrosive substances.

• The MPH2 rack PDU must be installed in a restricted-access location. A restricted-access location
is an area where access is possible only through the use of a tool or lock and key or other means of
security, and is controlled by the authority responsible for the location.

• The MPH2 rack PDU has no user-serviceable parts. Under no circumstances attempt to gain
internal access due to the risk of electric shock or burn.

• Refer any unexpected behavior or unusual fault conditions to your local dealer, Emerson
representative or Emerson Network Power Applications Engineering.

• Emerson recommends powering only devices with safety agency approval from the MPH2 rack
PDU.

• For permanently connected MPH2 rack PDU’s (hard-wired versions), a readily accessible
disconnect device must be incorporated external to the equipment.

• For MPH2 rack PDU’s with integral plugs, the socket/ outlet must be installed near the
equipment and must be easily accessible.

Important Safety Instructions

WARNING

Opening or removing end caps from an MPH2 rack PDU may expose personnel to lethal
voltages within the rack PDU. Observe all cautions and warnings. Failure to do so may result
in serious injury or death. MPH2 rack PDU units contain no user-serviceable parts. For
service or technical support, contact Emerson Network Power Applications Engineering or
your local Emerson representative. Do not attempt to service this product yourself.

CAUTION

Connecting an MPH2 rack PDU to a power supply with an incorrect rating in voltage or
amperes may damage the connected equipment and your MPH2 rack PDU. For questions
about the power supply connections, contact Emerson Network Power Applications
Engineering or your local Emerson representative.

CAUTION

Ensure that the ratings of the electric circuit of each connected device meets the specified
rating at each branch and outlet.

NOTE

For power management purposes, record the outlet where each piece of equipment is
connected. Outlets on the MPH2 rack PDU have a numeric designation. The MPH2 rack PDU
identifies the outlets with numbers and are grouped by branch with a letter referring to the
proper circuit breaker.

1.0 INTRODUCTION

The Emerson Network Power® MPH2™ is the most intelligent, high-availability line of managed rack
PDU’s. It offers remote monitoring and control capabilities as well as environmental sensors with
multiple power input selections and output configurations.

Metering Levels

Four types of MPH2 are available that offer metering of all electrical information including input,
branch and outlet levels, as well as integration with environmental sensors. The available
information varies by type of MPH2.

Mounting

Rack PDU’s are available for mounting in vertical configuration in standard or network enclosures.

Power cords on MPH2 models that mount vertically in a zero-U configuration may be switched from
one end to the other to accommodate top or bottom cable entry into the rack.

Locking Outlets - IEC Type Only

Locking outlets are available on models with IEC outlets. The locking feature requires optional power
cords to be installed on devices powered by the MPH2.

The outlets require no modification to function properly with non-locking power cords.

Overcurrent Protection

Introduction

All MPH2 rack PDU units with input current rating of 30A and higher feature 100% rated
hydraulic-magnetic breakers. For all UL-listed models, the maximum cord and plug-connected
loading is limited to 80% continuous loading, as required by UL in accordance with the National
Electric Code.

Low-profile circuit breakers are used on all MPH2 rack PDU’s with two or three branch circuits.
Standard-profile circuit breakers are used on MPH2 rack PDU’s that have six branch circuits or have
a 240VAC rating. Each type of circuit breaker is a flush-mount, rocker style (see Figure 29).

Integrated Monitoring and Management

The factory-installed Emerson RPC2™ communications module permits managing the MPH2 rack
PDU over a secure Web page and SNMP-based network management system. The RPC2 permits
interconnecting up to four rack PDU’s for monitoring and management.

NOTE

Refer to the RPC2 communications module user manual, SL-20841, for detailed instructions
on installing and using the RPC2 module. The document is available at Emerson’s Web site:

http://www.emersonnetworkpower.com

A rack PDU can be monitored locally through its onboard LCD, through a Web interface or through
an optional display module, either the RPC BDM (Part# RPCBDM-1000). The display module
connects directly to the RPC2 communications module. It can be handheld, mounted in or on the rack
or mounted on a wall near the rack PDU it is monitoring.

Multiple MPH2 rack PDU’s can be managed with these software applications:

1.3.1 Controls and Indicators—RPC2

The MPH2 rack PDU is monitored and managed by the factory-installed RPC2 communications
module. This manual presents information about the MPH2’s functions and features. For details on
operating the MPH2 through the RPC2 communications module, refer to the RPC2 user manual,
SL-20841. The document is available at Emerson’s Web site:

http://www.emersonnetworkpower.com

The RPC2 is installed near the middle of the MPH2 rack PDU. The central location eases connections
whichever orientation is required for power cabling.

The RPC2’s Web-based interface provides system operating measurements, as well as readings from
optional SN temperature or temperature/humidity sensors. The RPC2 provides basic information
about the MPH2 rack PDU, such as firmware version, unit rating, model number and serial number.

Introduction

1.3.2 Controls and Indicators—LED’s

The MPH2 rack PDU also has LED’s that indicate outlet and branch status and system information.
The LED’s flash, pulse or change colors to indicate an event or alarm condition (for details on how
LED’s respond to events and alarms, refer to 5.0 - Troubleshooting.

NOTE

Units with a “B” as the fourth character in the model name (MPHBxxxx) do not have LED’s at
their outlets. The branch and outlet LED behavior in 5.0 - Troubleshooting and elsewhere in
this document does not apply to these units.

Outlets on units with an “M” as the fourth character in the model name (MPHMxxxx) cannot be
turned Off. LED’s at outlets on these models are always either on continuously or flashing
when input power is present.

1.3.3 Controls and Indicators—Onboard LCD

Emerson’s MPH2 has an integrated, onboard LCD that can be used to view information about the
rack PDU. The information available depends on the type of MPH2. For additional information about
the onboard LCD, refer to 3.1.1 - Getting Information Through the Onboard LCD.
