2.1 MPX PRC—Power Rail Chassis/Power and Communication Bus
The MPX PRC acts as the fundamental building block of the Liebert MPX. Power and Communica-
tions buses are integrated into the full length of the MPX PRC. The MPX BRM (Branch Receptacle
Modules) and MPX PEM (Power Entry Module) lock onto the MPX PRC, adding power input, power
output, monitoring and management, depending on the type of module.
The MPX PRC is available in two lengths:
Part #
MPXPRC-V1880XXX
MPXPRC-V1035XXX
The MPXPRC-V1880XXX will accommodate up to six standard size (266 mm) MPX BRMs (Branch
Receptacle Modules); the MPXPRC-V1035XXX will accept up to three MPX BRMs. Each size of MPX
PRC also accepts a single MPX PEM. The PRC1035 will only accept variable capacity MPX PEM ver-
sions to retain the ability to carry the full complement of three standard size MPX BRMs.
The MPX PRC has five power bus slots that allow the connection of the MPX PEM and MPX BRM
modules to three phases of power, neutral and protective earth. A communication bus provides the
path through which the Liebert RPC, MPX PEM and MPX BRM modules communicate. The MPX
PRC also has a module connector slot that permits secure attachment of MPX PEM and MPX BRM
modules via their integral connectors. Spacer covers are available to cap off unused sections of the
MPX PRC's surface. The spacer covers reserve positions to insert MPX BRMs for future expansion.
