Quick Installation Guide
Before assembling and installing a
Liebert® MPX™, read and understand all
warnings and cautions in the Liebert®
MPX™ User Manual - Global Applications
which can be downloaded at www.
VertivCo.com.
Vertiv strongly recommends that the
MPX power entry module (PEM) be
installed by an individual who is properly
trained and qualified to perform electrical
work.
WARNING:
The Liebert MPX contains
high voltage that can cause serious
personal injury or death. The unit must be
installed in a restricted-access location.
NOTE:
If you need support for your MPX
power rail chassis (PRC), contact a Vertiv
representative. The MPX PRC contains no
user-serviceable parts. Never work alone.
De-energize the input power and discon-
nect power connections to all equipment
in the rack before installing a Liebert MPX
or connecting input power to the unit.
