Liebert MPXIPC-NXH30XXX User Manual

Variable-Capacity MPX PEM (Power Entry Module) versions require an MPX IPC (input power cord) 

to connect to utility power. The MPX IPC is available with various input plugs for single-phase or 

3-phase and up to 30A.
Quick-connect couplings are attached to the MPX IPC to ease proper connection to the MPX PEM 

(Power Entry Module). The connectors fit only one way, mating the proper input, ground and neutral 

wires on the power cord to the MPX PEM.
To attach the MPX IPC to an MPX PEM:
1. Ensure that utility power is not connected to any module or component.
2. Ensure that the MPX IPC is not connected to utility power.
3. Insert the quick-connect coupling on the MPX IPC into the connector on the MPX PEM. It will 

lock into place. Tug on the cord to determine whether it is securely attached to the MPX PEM.

Installing a Liebert

®

 RPC (rack PDU card) in the MPX PEM (Power Entry Module) permits 

monitoring a Liebert MPX either over a network or with an MPX BDM

™

 (basic display module). For 

complete details, refer to the Liebert RPC

™

 user manual, SL-20825, or quick-start guide, SL-20826, 

each available in the monitoring area of Liebert’s Web site, 

1. Locate the communication card bay on the MPX PEM. You might need to remove a cover.
2. Insert the Liebert RPC into the MPX PEM and secure it with the provided screws.
3. The Liebert RPC has four ports designated by icons: a LAN port, 

Expansion/Management port, Display port, and Sensor port. Connect an Ethernet 

cable (not included) to the LAN port, identified by the icon on the right:

4. Connect the Ethernet cable to a computer.

Risk of arc flash and electric shock. Can cause equipment damage, injury or death.
The MPX PEM contains hazardous voltage that could cause serious injury or death. This unit 

must be properly and securely installed on the MPX PRC

™

 (Power Rail Chassis). Emerson 

strongly recommends that the MPX PEM be installed only by an individual who has been 

properly trained and qualified to perform electrical work.
Whenever the MPX PEM is connected to power, the connectors on the bottom are energized 

with hazardous voltage. 
Connect input power only after:
• the MPX PEM (Power Entry Module) is properly installed on the MPX PRC (Power Rail 

Chassis) 

• the  MPX  IPC

™

 (Input Power Cord) is properly connected to the MPX PEM

Connect input power to the Liebert MPX only while the MPX IPC is properly connected to the 

MPX PEM. Failure to do so may subject the user to hazardous voltages.
