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 Environmental Parameters in Table 11).
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 at 180 degrees, and interior doors can be removed for more
flexibility in installations.
NOTE
The UPS must be placed a solid surface. There must be no openings in the surface except those
required for conduit landing areas. All provided kick plates must be installed.
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 (kg/cm
equipment. For weight details, see Table 11.
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.
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 23,000lb (10,433kg).
Locate center of gravity symbols
cabinet. Test lift and balance the cabinets before transporting. Maintain minimum tilt from
vertical at all times.
NOTICE
Risk of improper lifting. Can cause damage to front and rear panels.
Remove the front and rear panels before lifting the 1100kVA Liebert NXL unit. Failure to
remove these panels may cause them to be damaged when the UPS is lifted.
1.4.2

Clearances

The Liebert NXL has no ventilation grilles at either side or at the rear of the UPS. Clearance around
the front of the equipment should be sufficient to enable free passage of personnel with the doors fully
opened. It is important to leave a distance of 24in (610mm) between the top of the UPS and any
overhead obstacles to allow the module to be serviced and to permit adequate circulation of air coming
out of the unit.
