1. UPS definition
1.1. Purpose
The purpose of this specif ication is to define the design, manufacture and testing characteristics required in view of
supplying, putting into operation and maintaining an Uninterruptible Power Supply (referred to as a UPS
hereinafter).
The UPS shall be designed to supply dependable electric po wer to :
1.2. Brief description
The UPS shall be a single UPS, operating in double-conversion mode (also called on-line mode); it shall be a VFItype UPS (as per standa rd IEC 62040-2), made up of the fol lowing components, described in detail in this
specification:
ω Rectifier
ω Battery charger
ω Inverter
ω Battery
ω Automatic bypass (via a static switch)
ω Manual bypass (for maintenance)
ω User and communications interface
ω Battery management system
ω Any and all other devices required for safe operation and maintenance, including circuit breakers, switches, etc.
2. Operating principles
The UPS shall operate in double-conversion mode as indicated below.
2.1. Normal operation
(normal AC source available)
The rectifier shall supply the inverter and the charger with DC current. The inverter shall continuously supply the
load with backed up electrical energy and the charger shall float charge the battery.
2.2. Operation on battery power
(normal AC source not available or outside tolerances)
Upon failure or excessive deterioration of the normal AC source, the inverter shall continue to supply the load from
battery power without interruption or disturbance, within the limi ts i mpose d b y the bat ter y back up time.
2.3. Battery recharging
(normal AC source restored)
When the normal AC source is restored, the rectifier shall again power the inverter, without interruption or
disturbance to the load, while the charger automatica lly recharges the battery.
2.4. Transfer to bypass AC source
In case of a major overload or if the UPS shuts down, the static swit ch shall instantaneously tran sfer the load,
without a break in the supply of power, to the bypass AC source if it is available and within tolerances.
Transfer of the load back to the UPS output, synchronized with the bypass AC source, shall be automatic or
manual. During transfer, the load sh al l not suffer an outage or disturbance in the supply of power.
On request, the UPS system may automatically transfer the load with a micro-interruption (adjustable from 15 to
1000 ms) if a major faul t occurs on the UPS system and if synchronization with the bypass source has not been
established.
2.5. UPS maintenance
For maintenance purposes, the UPS shall include a mechanical manual bypass system with one-button operation.
For personnel safety during servicing or testing, this system shall be designed to isolate the UPS while continuing
to supply power to the load from the bypa ss AC source. The UPS shall also include a device making it possible to
isolate the rectifier and the charger from the normal AC source.

ω Steady-state conditions
Variations in the rated voltage shall be limited to ± 2% for a balanced load between 0 and 100% of the rated load,
whatever the voltage level on the normal AC source and the DC voltage lev el, withi n the li mits defined in sections
4.1 and 5.1.4.
ω Voltage variations for load step changes

current limiting to a peak capacity of ... [290 / 235 / 277 / 230 / 234 / 245% ] ... for 150 ms to allow highly disturbed
transient operating state s without transferring the load to th e bypass.
ω The overload capacity sh all be capable of taking into ac cou nt temperature conditions for more than ten minutes,
by allowing a continuous, 10% overload when the temperature is less than or equal to 20°C.
5.3.5. Higher power ratings for lower temperatures
It shall be possible to increase the power rating when the temperature is less than 35°C. The rating can be raised
by +3% for 30°C, +5% for 25°C and +8% for 20°C.
5.4. Automatic bypass
5.4.1. Load transfer to the automatic bypass
The UPS shall be equipped with an automatic bypass comprising a static switch. Instantaneous transfer of the load
from the inverter to bypass power and back shall t ake place without a break or disturbance in the supply of power
to the load, on the condition that the bypass source voltage and frequency are within the tolerances specified in
section 4.2 and that the inverter i s synch r on ized.
Transfer shall take place automatically in the event of a major overload or an internal inverter fault. Manually
