Final Positioning
When the equipment has been finally positioned, ensure that the adjustable stops are set so that
the UPS will remain stationary and stable (see 4.0 - Installation Drawings).
The Liebert
®
EXM
™
and its auxiliary cabinets must be installed on a concrete or equivalent, non-
resilient floor.
2.5 Mechanical Considerations
The Liebert
®
EXM
™
is constructed with a steel frame and removable panels. Top and side panels
are secured to the chassis by screws. The doors may be opened for access to power connections
bars, auxiliary terminals blocks and power switches.
The UPS comes with an Operator Control Panel that provides basic operational status and alarm
information. The cabinet houses the power components. Cooling is provided by internal fans. The
unit sits on four casters. Adjustable stops are provided to prevent the UPS from moving once it
has been moved to its final position.
The Input/Output Section (see Figure 1) provides the additional space to support wiring and
conduit landing for the 250kVA model of the Liebert

WARNING
Risk of heavy units tipping over while being moved. Can cause property damage, injury and
death.
Vertiv
™
recommends lifting the units by installing four eye bolts in the factory-fabricated
holes, one at each corner of the unit, attaching cables or similar strapping to the eye bolts
and lifting with a suitable mechanism.
AVERTISSEMENT
Le centre de gravité élevé des appareils présente un risque de renversement lors des
déplacements, peut entraîner des dommages matériels, des blessures et même la mort.
Vertiv
™
recommande de soulever les appareils en installant quatre anneaux de levage dans
les ouvertures fabriquées en usine, avec un anneau dans chaque coin de l’appareil, pour
ensuite fixer les câbles ou sangles aux anneaux afin d’effectuer le levage à l’aide d’un
mécanisme approprié.
