Liebert NX Installing the UPS Module
1.5 Positioning
To prolong the service life, the selected location must satisfy the following conditions:
 flat ground
 convenient wiring
 space for easy operation on UPS
 sufficient air exchange to dissipate heat produced by UPS
 protection against atmospheric agents
 protection against excessive humidity and heat sources
 protection against dust
 compliance with fire prevention requirements
 operating ambient temperature between 20°C and 25°C (the temperature range for max. battery efficiency)
The UPS consists of a steel frame structure with removable panels. The top and side panels are secured by screws. The power
terminals are located on the rear of the unit, and are covered by a removable panel that is held in place by screws. The UPS is also
equipped with casters and brake pads. Opening the UPS door enables the operator to access the communication interfaces and
power switches. The UPS features an operator control and display panel located on its front door, which provides basic operating
status and alarm information. The UPS air inlet is located at the front and the outlet is at the back.
1.5.1 System Cabinet
Depending on the specific design requirements, a UPS system may include certain equipment cabinets, such as UPS cabinet,
external battery cabinet, external bypass cabinet, etc. The cabinets should be installed side by side for aesthetic effect.
1.5.2 Moving the Cabinet
Warning
1. Ensure that the lifting equipment used to move the UPS cabinet is capable of supporting its weight. For the UPS weight, refer to
Table 8-3.
2. Ensure that sufficient personnel and lifting gear are available when removing the shipping pallet.
Note
Take special care when moving the UPS and the battery cabinet when fitted with batteries, and keep moving distance to a minimum.
Before moving the UPS, ensure that the four brake pads at the bottom plate of the UPS are in the raised position.
The UPS is equipped with casters for ease of movement over short distances (e.g. to when transferring the UPS from the shipping
pallet and when moving the cable-connected UPS to its final position). For larger distances, use a forklift truck or similar device to
move the UPS.
1.5.3 Clearance
Leave sufficient space in front of the UPS so that the front door can be opened fully and personnel can move freely when operating
the power switches and connecting the interface cables located behind it. It is necessary to leave enough space behind the UPS (at
least 350 mm) to permit the air it expels to circulate freely. Since the power input and output cables are connected to the rear of
the UPS, make sure also that the clearance behind it is sufficient to prevent the cables from being crushed when the UPS is moved
to its final position. It is also possible to leave a little space either side of the unit so that it can be moved back and forth.
1.5.4 Front Access
The component layout of the UPS supports front access and top access for servicing, diagnosing, and repairing the UPS. To allow
access to the power terminals on the rear, the UPS is mounted on casters. This reduces the space requirement for side and rear
access.
