WHITE PAPER
THE UPS IN DATA CENTERS AND THEIR MAIN FEATURES
Adaptability with electrical infrastructures (continued)
For small-medium power Legrand UPS can be easily connected with cables at the bottom front of the cabinet. This is
particularly useful and comfortable in case of cabling passing under technical floor. Nonetheless the UPS can easily be
connected also with cable coming from the top cable trays.
For large power Systems UPS can be connected both to cables and busbar power lines.
ADAPTABILITY TO THE ROOM AND BUILDING
Data Centers managers and designers pay great attention to the room space and footprint. In fact, both the occupied and
available space have a deep impact on costs and potential value of the infrastructure; in order to reduce the first factor
and increase the second one, it is fundamental to dedicate as much space as possible to active devices (rack for servers
and storage) and reduce to a minimum the space used by the rest of the technical infrastructure, UPS included.
For this reason, the UPS for Data Centers must have the highest level of power density and mechanical compactness.
Small footprint with compact cabinets, combined with wheels and adjustable feet, makes the UPS adaptable to the
building and technical room also in case of installation, movement and building renovation. Modular systems, with small
power modules, are furtherly comfortable and preferable due to the possibility for very few technicians to move empty
cabinets and modules and install them only after the final positioning easily and quickly. Even In case of high-power
UPSs (>500 kW), modular architecture, helps to simplify the movement, positioning and installation inside the building,
as these big UPS systems are made of a combination of several units in smaller cabinets. Furthermore it can be very
useful and interesting for a big power UPS to have the possibility to place the cabinets of its components not only in line
(side by side), but also along the walls (in L shape or U shape) or at the center of the room (back to back). Similarly, the
possibility to skip structural obstacles (e.g. pillars) by placing the single cabinets of components it is useful as well.
The Adaptability of the UPS to the technical room (accordingly with the case it could be Grey Room or Withe Room), is
also related to the environmental specs, proper ventilation system, mechanical compatibility with active load racks, cold
corridors and power distribution systems.
Connection with cables and busbars is possible
