Chapter 1 Installation Of UPS Module 3
NXr UPS Module And Parallel System 30kVA ~ 200kVA User Manual
1.4 Positioning
To prolong the service life, the place chosen should offer:
 convenient wiring
 space for easy operation on UPS
 sufficient air exchange to dispel heat produced by UPS
 protection against atmospheric agents
 protection against excessive humidity and heat sources
 protection against dust
 compliance with fire prevention requirements
 operating environment temperature between 20°C and 25°C (the typical temperature range for max. battery life)
The UPS is of steel frame structure wrapped by removable panels. The top and side panels are fixed by screws.
Opening the UPS door reveals the power terminals, auxiliary terminal block and power switch. The UPS has an
operator control and display panel located on its front door, which provides the basic operating status and alarm
information. The UPS provides air inlet in the front and air outlet at the back.
1.4.1 System Cabinet
Depending on the design requirement of each UPS system, a UPS system may include certain equipment cabinets,
such as UPS cabinet, external battery cabinet, external bypass cabinet, and so on. All the cabinets should be
installed side by side to achieve an aesthetic effect.
1.4.2 Moving Cabinet
Warning
1. The lifting equipment for moving the UPS cabinet shall have enough lifting capacity. For the UPS weight, refer to Table 8-3.
2. Ensure that adequate personnel and lifting aids are available when removing the shipping pallet.
Note
Take special care when moving the battery cabinet fitted with batteries, in which case, the moving distance shall be minimized.
The UPS can be moved by means of a fork lift or similar equipment.
1.4.3 Clearance
As the UPS has no ventilation grills at either side, no clearances are required for either side.
To enable routine tightening of the power terminations within the UPS, it is recommended that clearance around the
front of the equipment should be sufficient to enable free passage of personnel with the door fully open. Meanwhile,
maintain, for full 200kVA applications a rear clearance of at least 350mm to permit adequate circulation of air coming
out of the UPS, and advisably more than 500mm to facilitate maintenance.
1.4.4 Front Access
The component layout of the UPS supports front access and top access for servicing, diagnosing and repairing the
UPS, thus reducing the space requirement for side and rear access.
1.4.5 Final Positioning And Fixing
Figure 1-1 and Figure 1-2 provide the UPS installation dimensions. After final positioning, fix the UPS directly on the
installation surface through the anchor holes on the UPS base. If the UPS is mounted on raised floor, a suitable
pedestal should be designed, which should be able to bear the UPS weight. When designing the pedestal, refer to
the bottom view in Figure 1-1 and Figure 1-2.
