SAVE THESE INSTRUCTIONS

This manual contains important safety instructions. Read all safety, installation and operating
instructions before installing a Liebert MPX. Adhere to all warnings on the unit and in this manual.
Follow all operating and user instructions.
• The Liebert MPX is designed to deliver power to information technology and telecommunication
equipment. The Liebert MPX is not intended for use with life support or other designated critical
devices. If uncertain about its application, consult your local dealer or your Emerson representa-
tive.
• Maximum electrical load must not exceed that shown on the Liebert MPX module rating labels.
• Operate the Liebert MPX in an indoor environment only within an ambient temperature range of
41°F to 131°F (5°C to 55°C) with a relative humidity of 0% ~ 95%, non-condensing. Install it in a
clean environment, free of conductive contaminants, moisture, flammable liquids, gases and cor-
rosive substances.
• Do not continue to use the Liebert MPX if the LED panel or monitoring interface indicators are
not in accordance with these operating instructions (see 5.0 - Operation and Configuration).
Refer all faults to your local dealer, Emerson representative or Emerson Distributed Processing
Applications Engineering.
• Never insert any foreign object into a Liebert MPX.
• Do not connect equipment that could overload the Liebert MPX.
• Refer to 6.0 - Specifications to determine the electrical ratings and specifications of your Liebert
MPX. It is imperative that the input power supply ratings and connections match the specifica-
tions of the unit being installed.
WARNING
!
Opening or removing the cover of any Liebert MPX module with exception of the RPC cover on
the MPX PEM module, may expose you to lethal voltages within the unit.
Observe all cautions and warnings in this manual. Failure to do so may result in serious
injury or death.
Do not attempt to service this product. Liebert MPX modules contain no user-serviceable
parts. If you need support or have questions about your Liebert MPX, contact Emerson
Network Power Distributed Processing Applications or your local Emerson representative. Do
not attempt to service this product yourself.
Never work alone.
WARNING
!
The Liebert MPX contains high voltage that could cause serious personal injury or death. The
Liebert MPX 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. Access to the restricted location can be gained only by service personnel or users who
have been instructed about the reasons for the restrictions applied to the location and about
any precautions that should be taken.
CAUTION
!
Connecting your Liebert MPX and rack equipment to an input power supply with an incorrect
rating in voltage, amperes or phase may damage the connected equipment and your Liebert
MPX.
If you have questions about the power supply connections, contact Emerson Network Power
Applications Engineering or your local Emerson representative.
