TM

GalaxyTM 9000 cubicles can be moved short distances using a forklift or

high openings;
the unadjusted cubicle height (H) is 1900/2000 mm; after lifting the cubicle, the height can be adjusted ±10 mm by screwing in or out the four
feet;
the bearing surface corresponds to the area of the four cylindrical foot pads (60 mm diameter) positioned in each corner
of the cubicle;
the cubicle depth (D) is 840 mm (800 mm without doors and panels);
operating temperature range for rectifier-inverter, frequency converter or Static Switch Cubicles: 0 °C to 35 °C at rated output (40 °C for a
maximum of 8 hours) and 30 °C maximum for overload conditions. Operation outside the specified temperature range will reduce service life;
relative humidity: 95 % maximum;
maximum operating altitude without derating: 1000 m;
connection via the bottom for rectifier-inverter cubicles, or via the top with the addtion of an optional duct that can be installed on the right side
of the cubicle. The auxiliary and Static Switch Cubicles are designed for connections via the top
or bottom.
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 intercubicle connection cables are not supplied (except for the wires for auxiliary interconnections);
normally the cubicles do not have to be secured to the floor; the footpads nevertheless have holes with an average depth of 12 mm designed
for the fitting of M16 anchor bolts;
the cubicle doors are secured by Ronis locks (key 405).

1.4 Electrical parameters for selecting protective devices

The parameters given in the table below can be used to determine the required rating of the source side protective circuit
breaker on Mains 1 of a single-unit or modular UPS, a frequency converter, or a parallel UPS with SSC.

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.

Note:

For Mains 1 power supply voltages of 380, 400 and 415 V, the Mains 1 current is the same because it is a function
of the DC voltage.

(1) the rated Mains 1 currents (In) have been determined for a rated phase-to-phase voltage of 380 V to 415 V, a battery with a
15 minute backup time (206 cells at 2 V per cell, i.e. 412 V) and at the beginning of its recharge cycle, and full rated load with a
power factor of 0.9.
(2) the rated Mains 1 currents (In) have been determined for a minimum float charging voltage of 423 V and full rated load with
a power factor of 0.9.
(3) the Mains 1 currents given for an overload of 25 % or 50 % are maximum values. They have been determined for a battery
drawing the minimum float charging voltage and a load power factor of 0.9. 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.

The parameters given in the table below can be used to determine the required rating of the source side protective circuit
breaker on the Mains 2 line for a single-unit or modular UPS.

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.
This choice must also be made so as to protect the static switch semiconductors and ensure discrimination with respect to
the UPS output fuses (refer to "appendix" chapter).
– For an installation with a Static Switch Cubicle, the Mains 2 currents indicated in the table must be multipled by the number
of parallel-connected rectifier-inverter cubicles required to supply the load power (i.e. without taking redundant rectifier­inverter units into account).

Remark:

If the installation includes a transformer on the Mains 2 input, allow for the inrush current caused by magnetization of the
transformer windings.

rated load as well as overloads of 25 % or 50 %. When choosing the circuit breaker rating, use the "rated curent" column and check
that the circuit breaker tripping curves are compatible with the data in the overload columns.
For a Mains 2 voltage of 380 V, multiply the currents indicated in this table by 1.09.
For a Mains 2 voltage of 400 V, use the table in another language version of this manual.

– the current values and cable cross-sections for Mains 1 are given for full rated load with a power factor of 0.9 and a battery
consuming its minimum float charging voltage;
– the battery current values and cable cross-sections have been determined for a battery at the end of a charge cycle;
– the current values and cable sections for Mains 2 and load are given for full rated load with a power factor of 0.9.
For frequency converters, the parameters concerning Mains 2 are not applicable.
The load parameters common to all the converters are given in the table below.

Characteristics

The table below serves as an example for an installation comprising up to four frequency converters or four parallel UPSs
with a centralised SSC.
– for installations with redundant units, take into account only the units required to supply the load power
(e.g. for an installation made up of 3 parallel-connected rectifier-inverter cubicles, one being redundant, only 2 rectifier­inverter cubicles are used to determine Mains 2 and load currents and cable cross-sections);
– this table has been drawn up for rated phase-to-phase Mains 2 and load voltages of 415 V and full rated load with a power
factor of 0.9. For voltages of 380 or 400 V, multiply the indicated currents by 1.09 and 1.04 respectively, then modify the cable
cross-sections accordingly if necessary.
The cable cross-sections in this table are for the parts illustrated in bold on the following block diagrams (installation examples,
figures 1 and 2).

Characteristics

The table below serves as an example for an installation with up to four modular UPSs with an external maintenance bypass.
– for installations with redundant units, take into account only the units required to supply the load power
(e.g. for an installation made up of 3 parallel-connected rectifier-inverter cubicles, one being redundant, only 2 units are used
to determine the currents on the maintenance bypass line and the load, and the cross-sectional areas of cables);
– this table has been drawn up for rated phase-to-phase Mains 2 and load voltages of 415 V and full rated load with a power
factor of 0.9. For voltages of 380 or 400 V, multiply the indicated currents by 1.09 and 1.04 respectively, then modify the cable
cross-sections accordingly if necessary.
The cable cross-sections in this table are for the parts illustrated in bold on the following block diagrams (installation example,
figure 3);
– important. In an installation with an external maintenance bypass, the power cables between each UPS and the

upstream protection devices must be the same length. The same holds for the power cables between each UPS cubicle
and the external maintenance bypass.

2. Installation (to be carried out by qualified personnel only)

2.1 Handing

Unpacked cubicles may be moved using a forklift from the front or from the back. Distances must not exceed a few meters.

2.2 Positioning the cubicle

– prior to moving the cubicles to their final position, remove the packing material and withdraw the base panels from the space
on the side created by the spacing uprights. The panels will be installed at the end of the installation procedure;
– spacing uprights on the sides of the cubicles create a 50 mm clearance when cubicles are positioned next to each other,
enabling users to open the doors (see figure 4). If a cubicle is installed next to a wall, leave additional space so that the cubicle
is 50 mm from the wall;
– when the spacing uprights are not required (cubicles are not positioned next to a wall or another cubicle), they may be
removed:
– loosen the four screws securing the upright,
– lift the upright and pull it free,
– replace the long gold-coloured screws with the black screws supplied in a bag attached to the cable terminals in the cubicle;
– adjust the height of the feet until the first cubicle is perfectly vertical; adjust the feet of the subsequent cubicles so that the
all the doors are perfectly aligned.

2.3 Floor loads (figure 5)

– the floor supports the weight of each cubicle via the four 60 mm diameter pads at the bottom of the feet screwed into the
corners of the frame;
– the exact locations of the footpads are indicated in the figure;
– normally the cubicles do not have to be secured to the floor; the footpads nevertheless have holes with an average depth
of 12 mm designed for the fitting of M16 anchor bolts;
– to determine the stresses applied by the cubicle feet on the floor, divide the cubicle weight (see the first 3 tables of this
manual) by the total area of the 4 footpads (110 cm

2.4 Cubicle layout on false floor or normal floor (figures 6, 7, 8)

– the cubicles can be installed directly up against the rear wall;
– an overall clearance of 400 mm must be left above the entire surface of the cubicles for ventilation;
– a side clearance of 25 mm is provided by the vertical bars on the sides of the cubicles to allow door opening. For cubicles
mounted side by side, the two adjacent bars ensure an inter-cubicle clearance of 50 mm;
– a minimum clearance of 1000 mm is required in front of the cubicles to allow complete opening of the doors and easy
access for maintenance work (replacement of subassemblies);
– for extended battery backup times or high output systems, the UPS may have several battery cubicles (see the table at the
end of the previous chapter). If this is the case, install the battery cubicles on the left side of the rectifier-inverter cubicle with
the cubicle containing the battery circuit breaker QF1 closest to the rectifier-inverter cubicle (figure 7);
– when an auxiliary cubicle is included in the UPS, it should be installed to the left of the battery cubicle(s);

connection via the bottom

The connection cables may be run in three ways:
– in a cable trench running underneath the front of the cubicles (see trench dimensions and layout in figure 6),
– under a false floor. A cutout must in this case be made in the floor for cable entry (see figure 6 for dimensions),
