IMPORTANT SAFETY INSTRUCTIONS
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.
!
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.
