6000 : Specification guide
Parallel UPS, three-phase, 250 to 3000 kVA*
* Power rating for an N+1 redundant configuration
APC By Schneider Electric Edition - 03/2009 Spec. E - 7
specified by the battery supplier (0.1 x C10 for a sealed lead-acid battery).
5.1.4 - Operating mode
The charger of each UPS unit shall be sized to recharge the battery rapidly:
a battery with a backup time of…[5 / 10 minutes in less than 11 hours] [15 minutes in less than 13 hours] (following
a discharge to Pn/2 to recover 90% of backup time).
5.1.6 - Input power factor
The required level of performance is indicated in section 3.5 "Limitation of harmonics upstream of the UPS".
5.1.7 - Voltage regulation
Rectifier/charger regulation shall take into account the ambient temperature of the battery and shall ensure DC
output voltage fluctuations of less than 1% irrespective of load and AC input voltage variations (within the limits
specified in section 4.1 “Normal AC source”).
5.2 - Batteries
Each UPS unit shall be equipped with its own battery of the …[sealed lead-acid type, factory mounted and wired in
a cabinet identical to that of the UPS,] … [sealed lead-acid type, mounted on shelves,]…[vented lead-acid type,
mounted on a rack,]... with a service life equal to at least …[5 / 10]… years.
Each battery shall be sized to ensure continuity in the supply of power to the corresponding inverter for at least
…[8 / 10 / 15 / 30 / 60…]… minutes, in the event of a normal AC source failure, with the inverter operating at full
rated load, i.e.
kVA at a power factor (pf) of 0.8.
Sizing calculations shall assume an ambient temperature between 0° C and 35° C
The UPS shall include devices to ensure:
ω effective battery protection (see section 8.4 "Protection - Battery");
ω battery management (see section 9 "Battery management").
5.3 - Inverter
Each inverter shall be sized to supply a rated load of …[ 250 / 300 / 400 / 450 / 500 / 600 ]… kVA at 0.8 pf and
shall satisfy the specifications listed below.
5.3.1 - Output voltage
ω Rated voltage
…[ 380 / 400 / 415 ]… volts rms, adjustable via the user interface (see section 10), within tolerances of +/- 3%.
ω Number of phases
3 phases + neutral + earth.
ω Steady-state conditions
The variation in the rated voltage shall be limited to ± 2% for a balanced load between 0 and 100% of the rated
power, irrespective of normal AC input and DC voltage levels, within the limits specified in section 4.1 “Normal AC
source” and 5.1.4 “Rectifier/charger - Operating modes and DC-voltage levels”.
ω Voltage variations for load step changes
Output voltage transients shall not exceed ± 1% of rated voltage for 0 to 100% or 100 to 0% step loads. In all
cases, the voltage shall return to within steady-state tolerances in less than 100 milliseconds.
ω Unbalanced load conditions
For a load unbalance greater than 30%, the voltage unbalance shall be less than 2% for the phase-to-neutral
amplitude and 3 degrees for the phase angle deviation.
5.3.2 - Output frequency
ω Rated frequency
- 50 or 60 Hz.
ω Variations in free-running frequency mode:
- ± 0.5 Hz.
