Electrical parameters for selecting protective devices
Normal AC source
The parameters given in the table
opposite can be used to determine the
required rating of the upstream
protective circuit breaker on the normal
AC input for one single-UPS or parallel-
UPS unit, a unit in economy mode or a
frequency converter.
Important:
It is essential to choose the type of
circuit breaker according to its breaking
capacity and the prospective short-
circuit current at its place of installation
(see Schneider Electric LV
documentation).
Note:
For normal AC source power supply
voltages of 380, 400 and 415 V, the
normal AC source current is the same
because it is a function of the DC
voltage.

UPS cubicles
Characteristics
(cont.)
◗
the cubicles are cooled by forced
ventilation. The air enters via the doors
and grids at the bottom and is
discharged through the back, or
through the roof for the 1900 mm high
cubicles (except the 160 and 200 kVA
units from which the air is discharged
through the roof only, which means the
cubicles can be positioned against the
back wall).
◗
connections are made through the
bottom. Connections through the top
are available on option for all 1900 mm
high cubicles (except the 160 and
200 kVA units).
◗
the connection cables may be run in
three ways:
◗
in a trench running under the
cubicles,
◗
under a false floor,
◗
on the floor under the cubicles, in the
free space equal to the height of the
feet; in this case the cables should be
run side by side to avoid blocking the
flow of air for ventilation;
◗
the cables for connections between:
◗
the battery and UPS cubicles (power
and control cables);
◗
the bypass AC-source transformer in
an auxiliary cubicle and the UPS
cubicle can be supplied on option.
Layout must comply with figures 5, 6
and 7. The other power cables for
connections between cubicles are not
supplied.
◗
only the wires for the intercubicle
control connections between parallel-
connected UPS units are supplied;
◗
the cubicle doors are secured by
SOUTHCO locks (key CH751).
(1) the indicated weights are for the empty
cubicles, without the batteries because the total
battery weight may vary widely.
(1) the rated normal AC source currents (In) have
been determined for a rated phase-to-phase
voltage of 400 V, a battery with a 10 minute
backup time at the beginning of its charge with 206
cells at 2 Volts per cell (412 Volts) and full rated
load with a power factor of 0.8.
(2) The rated normal AC source currents (In) have
been determined for a minimum float charging
voltage of 423 V and full rated load with a power
factor of 0.8.
(3) the normal AC source currents given for an
overload of 25% or 50% are maximum values.
They have been determined for a battery with
minimum float charging voltage and a load power
factor of 0.8. When choosing the circuit breaker
rating, use the "rated current" column and check
that the circuit breaker tripping curves are
compatible with the values in the overload
columns.
