1.2 - Brief description
The UPS system shall be made up of …[ 2 / 3 / 4 / 5 / 6 ]…identical parallel-connected UPS units with the same
power rating, operating in double-conversion mode (also called on-line mode) in accordance with the VFI category
described in standard IEC 62040-2.
Each UPS unit shall have a unit rating of …[ 250 / 300 / 400 / 450 500 / 600 / 800 ]… kVA, made up of the following
components, described in this specification:
ω rectifier;
ω battery charger;
ω inverter;
ω battery;
ω a battery-management system.
In addition, the UPS shall be equipped with:

ω a centralized bypass shall be made up of the following components:
- static bypass (via a static switch);
- manual maintenance bypass.
The centralized bypass shall be sized to support the entire load. Consequently, its power rating shall be
…[ 250 / 500 / 800 / 1200 / 2000 …] kVA.
ω a user and communications interface for the entire UPS system.
The UPS system shall also comprise any and all other devices required for safe operation and maintenance,
including circuit breakers, switches, etc.
The UPS system shall ensure continuity of electric power to the load within the specified tolerances, without
interruption upon failure or deterioration of the normal AC source (utility power) for a maximum protection time
determined by the capacity of the backup batteries installed.
