ONSIDERATIONS
1.3.1
Room
The Liebert EXM Parallel Cabinet is intended for indoor installation and should be located in a
cool, dry, clean-air environment with adequate ventilation to keep the ambient temperature
within the specified operating range (see
).
All models of the Liebert EXM Parallel Cabinet are convection-cooled. To permit air to enter and
exit and prevent overheating or malfunctioning, do not cover the ventilation openings.
When bottom entry is used, the conduit plate can be removed and punched and replaced. The
bottom conduit plate must be replaced for proper airflow. If necessary to cool the room, install a
system of room extractor fans.
1.3.2 Storage
Should the equipment not be installed immediately, it must be stored in a room for protection
against excessive humidity and or heat sources (see

OSITIONING
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminals blocks and power switches is from the top and
sides.
The top and side removable panels are secured to the chassis by screws. The side panel can be
removed for access to the power connections bars, auxiliary terminal blocks and power isolators.
1.4.1
Moving the Cabinets
The route to be travelled between the point of arrival and the unit’s position must be planned to
make sure that all passages are wide enough for the unit and that floors are capable of supporting
its weight (for instance, check that doorways, lifts, ramps, etc. are adequate and that there are no
impassable corners or changes in the level of corridors).
Ensure that the cabinet weight is within the designated surface weight loading (kg/cm
2
) of any
handling equipment. See
for the weight of the Liebert EXM Parallel Cabinet 300mm,
600mm and 800mm models.
Ensure that any lifting equipment used in moving the cabinet has sufficient lifting capacity.
The Liebert EXM Parallel Cabinet can be handled with a forklift or similar equipment. For
operations with a fork lift, refer to installation drawings in
.
Because the weight distribution in the cabinet is uneven, use extreme care during handling and
transporting.
When moving the unit by forklift, care must be taken to protect the panels. Do not exceed a
15-degree tilt with the forklift.
NOTE
The Liebert EXM Parallel Cabinet is suitable for mounting only on concrete and other
noncombustible surfaces.
