3.1.3 Prepare the Liebert
®
MPX
™
for Mounting
1. Insert two spring nuts into the T-slot on the back of the MPX PRC
™
, one near either end (see
Figure 9 for how to insert a spring nut).
2. Position the spring nuts where the brackets to be used will be positioned (either the Z-shaped or
L-shaped brackets). To move a spring nut, press down on it with a small, pointed object and slide
it into position.
3. Thread an MPX mounting screw into the spring nut and tighten a few turns. Leave enough space
for the bracket to slip over the screw’s head and rest on the body of the screw.

Horizontal Frame Member
1. Insert two spring nuts into the T-slot on the upper horizontal frame member.
a. To use the Z-shaped bracket, insert the spring nuts into the T-slot on the face of the horizontal
frame member (see Figure 10).
b. To use the L-shaped bracket, insert the spring nuts into the T-slot on the thinner side of the
horizontal frame member (see Figure 10).
2. Position the spring nuts to accommodate screws inserted through slots in the brackets. To move
the spring nuts, press down on each with a small, pointed object and slide each into position.
3. Hold the bracket in place and attach it with two of the M5x10 screws with hex heads.
4. Tighten the hex-head screws firmly with the Allen wrench.
5. Repeat Steps 1 through 4 for the lower horizontal frame member. The brackets must be directly
in line with each other for the Liebert
®
MPX to be installed.
6. After the brackets are attached, hang the Liebert MPX in the rack by inserting the Liebert MPX
mounting screws into the slots on the brackets (see Figure 12).
7. Tighten the Liebert MPX mounting screws securely.
