Liebert MPXIPC-NXH30XXX User Manual

All configuration steps must be completed before attempting to startup equipment connected to the 

Liebert MPX.

Emerson recommends installing the MPX PRC

™

 (Power Rail Chassis) in the rack, then attaching the 

Liebert MPX modules to it.
Before beginning, consider how cables will be routed in the rack. Placing the MPX PEM

™

 (Power 

Entry Module) at the end of the MPX PRC

™

 that is nearest the entry point for its input power cable 

can ease cable routing and help separate control and power cables to reduce electromagnetic 

interference.
A Liebert MPX can be installed in a Knurr

®

 Miracel

™

 rack on either the upright or horizontal frame 

member with the included hardware. The unit can be installed on the face of the frame member or on 

the side of the frame member.
Installation requires inserting two spring nuts into the Liebert MPX, screwing Liebert MPX 

mounting screws into the spring nuts and attaching two brackets to the Knurr Miracel frame 

members. The Liebert MPX hangs on the brackets and is supported by the Liebert MPX mounting 

screws.

• Z-shaped brackets: 2
• L-shaped bracket: 2
• Spring-nuts, M5: 6
• Screws, M5x10: 6
• Liebert MPX mounting screws, 2

• Slotted screwdriver
• 4mm Allen wrench

Risk of connecting two MPX PEMs to one MPX PRC. Can cause equipment damage, injury or 

death.
Connect only one MPX PEM

™

 (Power Entry Module) to an MPX PRC (Power Rail Chassis). 

Connecting more than one MPX PEM could cause cross-conduction. A cross-conduction can 

cause upstream overcurrent protective devices (OCPD) trip or the resulting short circuit 

current may exceed the OCPD A.I.C. ratings.
