PART 2 - PRODUCTS

2.1 OPERATING PRINCIPLES

A. The UPS system shall operate in double-conversion mode, described in detail in

this specification.

B. 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.

C. Operation on battery power (normal AC source not available or outside toler-

ances): Upon failure or excessive deterioration of the normal AC source, the in-

verter shall continue to supply the load from battery power without interruption or

disturbance, within the limits imposed by the battery backup time.

D. Battery recharge (normal AC source restored): When the normal AC source is

restored, the rectifier shall again power the inverter, without interruption or dis-

turbance to the load, while the charger automatically recharges the battery.

E. Transfer to bypass AC source:

1. In case of a major overload or if the UPS shuts down, the static switch shall

instantaneously transfer the load, without a break in the supply of power, to

the bypass AC source if it is available and within tolerances.

2. Transfer of the load back to the UPS output, synchronized with the bypass

AC source, shall be automatic. During transfer, the load shall not suffer an

outage or disturbance in the supply of power.

3. On request, the UPS system may automatically transfer the load with a micro-

interruption (adjustable from 15 to 1000 ms) if a major fault occurs on the

UPS system and if synchronization with the bypass source has not been es-

tablished.

4. In all cases, to ensure load transfer in complete safety, the system shall sim-

ultaneously control all the static switches.

G. UPS maintenance:

1. All power and control electronics of the modular UPS units making up the

UPS system shall be accessible from the front of the UPS.

2. For maintenance purposes, the UPS system shall include an external, me-

chanical, manual bypass system with one-button operation, common to all

modular UPS units.

3. For personnel safety during servicing or testing, this system shall be designed

to isolate the UPS system while continuing to supply power to the load from

the bypass AC source. The UPS shall also include a device making it possi-

ble to isolate the rectifier and the charger of each modular UPS unit from the

normal AC source.

H. Battery maintenance: For safe maintenance on the battery, the system shall in-

clude a circuit breaker to isolate the battery from the rectifier, the charger and the

inverter. When the battery is isolated from the system, the UPS shall continue to

supply the load without interruption or disturbance, except in the event of a nor-

mal AC source outage.

I. Cold Start (normal AC source absent): The battery shall be capable of starting

the UPS if the normal AC source is absent and continue supplying power to the

load within the specified backup time. Cold start on battery power shall be possi-

ble on the condition that the system shall have started at least once on normal

AC power.

cables.

b. Number of phases: 3 phases + neutral + earth.

c. 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

synchronisation system shall automatically limit the phase deviation

between the voltages to 3 degrees, if the bypass source frequency is

sufficiently stable (within adjustable tolerances of 0.5% to 8% with respect

to the rated frequency).

b. Synchronisation with an external source: It shall be possible to

synchronise with all types of external source.

c. Autonomous operation following loss of synchronisation with by-pass power: When the bypass source frequency deviates beyond these

limits, the inverter shall switch over to free-running mode with internal

synchronisation, regulating its own frequency to within ± 0.02 Hz. When

bypass power returns to within tolerances, the inverter shall automatically

resynchronise.

d. Variation in frequency per unit time: To avoid transmitting to the

inverter any excessive frequency variations on the bypass AC source

when it is within tolerances, inverter frequency variations per unit time

(dF/dt) shall be limited to 1 Hz/s or 2 Hz/s (user defined).

turbed transient operating states without transferring the load to the by-

pass.

conditions for more than ten minutes, by allowing a continuous, 10% over-

load when the temperature is less than or equal to 20°C.

1. Load transfer to the static bypass: a. The UPS shall be equipped with an automatic bypass comprising a static

switch

b. Instantaneous transfer of the load from the inverter to bypass power and

back shall take 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 specified tolerances and that the inverter is synchronised.

c. Transfer shall take place automatically in the event of a major overload or

an internal inverter fault. Manually initiated transfer shall also be possible.

d. If the bypass power is outside the specified tolerances or is not synchro-

nised with the inverter, automatic transfer of the load from the inverter to

bypass power shall take place after a calibrated interruption adjustable

from 15 to 1 000 milliseconds.

ic switch shall be capable of handling an over current of 18times the rated

current of the UPS to facilitate discrimination within the electrical installation.

E. Discrimination and short-circuit capacity

make it possible to use the short-circuit power of the bypass source to trip the

downstream protection devices of the inverter.

2. To ensure tripping in a selective manner, the total available power shall be

sufficient to trip protection devices with high ratings (circuit breaker rated In/2

or UR fuses rated In/4, where In is the rated inverter current).

3. If the bypass source is outside the specified tolerances, all the inverters in

operation shall, for the same discrimination requirements, be capable of trip-

ping circuit breakers rated In/2 or UR fuses rated In/4, irrespective of the type

of short-circuit.
