WARNING: Before assembling and

installing a Liebert® MPX™, read

and understand all warnings and

cautions in the Liebert® MPX™ Rack

Power Distribution Unit User Manual

which can be downloaded at www.

VertivCo.com.

The Liebert® MPX contains high voltage

that can cause serious personal injury or

death. The unit must be installed in a

restricted-access location.

To attach an MPX™BRM to the

MPX™PRC:

1. Preparing for installation

Ensure the module’s circuit

breaker is in the o/open

position and ensure the screw

latches at each end of the MPX

branch receptacle module

(BRM) are positioned to fit into

the MPX power rail chassis (PRC)

slot.

2. Aligning the MPX BRM power

blades

Position the module so the

power blades fit into the power

bus on the MPX PRC.

3. Connecting the module to

the MPX PRC

Press the module firmly onto

the MPX PRC until the bottom

of the MPX BRM is flush to the

surface of the MPX PRC.

4. Securing each MPX BRM

to the MPX PRC

Use a Pozidriv® (PZ1)

screwdriver to press each screw

latch downward. Turn the screw

latch 90 degrees (one-quarter turn)

to seat the locking tab. Turn the

screw latch an additional 180

degrees (one-half turn) until it locks.

WARNING: Do not use power tools

or pneumatic equipment to secure

the screw latch.

Do not turn the screw latch

more than 270 degrees (a

three-quarter turn).

NOTE: If using a torque-limiting

screwdriver, carefully press the

screw downward first before turning.

To prevent damage to the latches,

do not exceed a maximum torque of

18 in/lbs (2 Nm).

5. Verifying installation

Conduct a visual inspection to

verify the MPX BRM has been

properly installed. A slight side-

to-side rocking of the module

should not cause separation

from the MPX PRC surface.
