50 energetica INDIA- Oct-Nov_2021 Down time of Data Center means down time of digital service with consequence interruption of activities in the so- ciety, problems for people and companies, huge money losses and, sometimes, even dangerous situations. Minor mains disturbances, such as voltage sags and surge, micro-interruptions and flickers, can cause severe damage to data and servers in the long term, as well, with consequent breakdowns for failures and repairs. Installing a UPS system in a power supply line greatly helps business continuity by filtering mains disturbances and outages. The intense, fast and constant evolution of the “Digital World” is reflected in frequent modifications and upgrades of the dig - ital infrastructures. Today, digital services are indispensable in daily life of the modern society. Public Administration, Health, Finance, Telecommunications, Commerce, Industry, Entertain - ment and many other sectors are deeply dependent and em - powered by digital services, devices and infrastructures. Data Centers are the hidden core behind our daily “digital life” which allows us to use and receive digital services. In addition, over the last few years Data Centers have experienced a huge evolution and diversification in their final scope. In fact, they passed from private company or public office Server Room to Clouds, Colocations, Hybrid, Edge, Hyperscale systems: dif - ferent power sizes, different services, different management of the IT active load which also means different energy usage and management.

POWER SECTOR The UPS for Data Centers and the Main Features it has to Guarantee Electric infrastructures in Data Centers can be various and very specific according to the power size, geographical po - sitions, local laws, technical/design choices, building typolo - gy and other several reasons. Electric infrastructure may also change along the time, in case of renewal, reorganization or enlargement of the Data Center. In other cases, the room and the electric system already exist, they were originally used for other applications and currently are supposed to house a serv - er farm or other IT infrastructures. A UPS which is designed to be compatible (natively or easily configurable) with various electric infrastructures is, for sure, a great advantage with con - sequent time and cost saving. Compact footprint Numeric UPS are designed to be compatible with wide sce - narios of electric systems. They are all compatible with the dif - ferent grounding system, can work with isolation transformer both in input and output. Legrand pays particular attention for the ergonomics of the UPS with the User and the Application and reach high level of usability and integration for the best ex - perience in UPS management. For best usage of the available space in Data Centers, Numeric UPS are designed to have ones of the highest level of power density in the market with consequent compact foot - print. For example, ventilation in Keor HPE is designed to flow from top and front, without the need of free space on the rear side of the cabinet for easy installation against the wall. Top and front ventilation allow installation against the wall with floor space savings
