Leveling in Final Position
When the equipment has been finally positioned, ensure that the adjustable leveling feet are set so
that the UPS will remain stationary and stable (see 7.0 - Installation Drawings ).
1.5.4 Clearances
There are no ventilation grilles on the sides or rear of the UPS. The sides must be accessible during
installation. After installation, the unit may be placed with the rear against a wall and optional cabi-
nets on either side.
To enable routine tightening of power terminations within the UPS, make sure there is sufficient
clearance in front of the NX to permit free passage of personnel with the door fully opened.
Leave a minimum of 2 ft. (610mm) between the top of the UPS and the ceiling to permit adequate air
circulation above the unit. Liebert recommends against using air conditioning or other systems that
blow air onto the top of the unit.
1.5.5 Floor Installation
The diagrams in 7.0 - Installation Drawings show the location of holes in the base plate for bolting
the equipment to the floor. An optional anchoring kit is available. For information, see your local Lie-
bert representative.
If the equipment is to be placed on a raised floor, it should be mounted on a pedestal that will support
the equipment point loading. Refer to the bottom view in Figure 23 to design this pedestal.
1.5.6 Cable Entry
Cables can enter the NX from the top, through the bottom or through the left side. Cable entry is
made possible by removing the left-side panel or a metal plate attached to the top or bottom of the
UPS.
Connecting cables to the NX requires that the UPS be accessible from the left side to allow personnel
to complete the connections and make necessary adjustments. After installation is complete, the NX
may be serviced from the front.

WARNING
The casters are strong enough for movement across even surfaces only. Casters may fail if
they are subjected to shock loading, such as being dropped or rolled over holes in the floor or
obstructions. Such failure may cause the unit to tip over, injuring personnel and damaging
the equipment.
Care must be taken when maneuvering units fitted with batteries. Keep such moves to a
minimum. For further information, see Battery Cabinet Precautions on page 2 .
NOTE
When installing the UPS, the customer must provide a disconnect at the output of the UPS.
