  • Page 5: Important Safety Instructions

    This manual contains important safety instructions. Read all safety, installation and operating instructions before installing a Liebert® MPX™ rack PDU. Adhere to all cautions and warnings on the unit and in this manual. Upon installation, follow all operating and user instructions.
  • Page 6 Liebert® MPX™ rack PDU. Never insert a foreign object into an MPX module, particularly into the MPX PRC, with the exception of the RPC-1000™ and RPC2™ communications modules. Each module has a small hole between the display and sensor RJ45 connectors to reset the card.

  • Page 7: Introduction

    1 INTRODUCTION The Liebert® MPX™ is an adaptive rack power distribution unit (PDU) built with modular and scalable components that can be installed and reconfigured on-site to meet varying input and output power connectivity needs. For optimal flexibility, ensure that the modules match the power requirements of the application.

  • Page 8: Mpx™ Prc: Power And Communication Bus

    The MPX PRC is available in different lengths to accommodate a single MPXP PEM and up to seven MPX BRMs. The MPX PRC has five power bus channels that allow you to connect the MPX PEM and MPX BRM modules to up to three phases of line, neutral and protective earth. The communication bus allows the Liebert RPC, MPX PEM and MPX BRM modules to communicate with each other.

    2.1.2 Attaching brackets The brackets must be installed before the PDU is installed. NOTE: The brackets will attach the Liebert MPX rack PDU more securely if one is near the top of the unit and one is near the bottom. To attach brackets to an upright frame member: Insert two spring nuts into the T-slot on a rear upright frame member.
