Environmental Considerations
1.3.1 UPS Room
The UPS module 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
in
The Liebert
e
XL UPS is cooled with the aid of internal fans. To permit air to enter and exit and
prevent overheating or malfunctioning, do not cover the ventilation openings.
The Liebert
e
XL UPS is equipped with air filters located behind the front doors. A schedule for
inspection of the air filters is required. The period between inspections will depend upon
environmental conditions.
When bottom entry is used, the conduit plate must be installed.
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
).
1.4
Positioning
The cabinet is structurally designed to handle lifting from the base.
Access to the power terminals, auxiliary terminal blocks and power switches is from the front.
The door can be opened to give access to the power connection bars, auxiliary terminal blocks and
power isolators. Front door can be opened to 90 degrees, and interior doors can be removed for more
flexibility in installations.
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 UPS weight is within the designated surface weight loading (lb/in
2
) of any handling
equipment. For weight details, see
.
The UPS can be handled with a forklift or similar equipment. Ensure any lifting equipment used in
moving the UPS cabinet has sufficient lifting capacity. When moving the unit by forklift, care must be
taken to protect the panels. Do not exceed a 15-degree tilt with the forklift. Bottom structure will
support the unit only if the forks are completely beneath the unit.
Handling with straps is not authorized.
NOTE
The UPS is suitable for mounting on concrete or other non-combustible surface only.
NOTE
The UPS must be placed on a non-combustible surface suitable to support the weight of the
unit.
!
WARNING
Risk of heavy unit falling over. Improper handling can cause equipment damage, injury or
death.
Because the weight distribution in the cabinet is uneven, use extreme care while handling
and transporting. Take extreme care when handling UPS cabinets to avoid equipment
damage or injury to personnel.
The UPS module weight is up to 5187 lb. (2353kg).
Locate center of gravity symbols
and determine unit weight before handling each
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
