GalaxyTM 6000 cubicles can be

moved short distances using a forklift or
pallet-mover when the front, rear and
side base panels are not mounted. The
forks can be inserted from all four sides
into 100 mm
+/– 10 mm 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).

Characteristics (cont.)

Electrical parameters for selecting protective devices

The parameters given in the table
opposite 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 short­circuit current at its place of installation.

Note:

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

The parameters given in the table
opposite 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 short­circuit 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 rectifier-inverter 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.

(to be carried out by qualified personnel only)

Handling

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

Positioning the cubicles

(for 600 kVA UPSs, see the appendix
as well)

◗ 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.

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),

Installation (cont.)

◗◗ 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
exit from the rear or sides of the
cubicles;

◗ connection via the top

◗◗ the Static Switch, filter and auxiliary

cubicles are designed for connection
via the bottom or top,

◗◗ for the rectifier-inverter cubicles, a

special 400 mm wide connection duct
must be added to the right of the
cubicle to allow connection via the top.

Power circuit wiring diagrams

The single-wire diagrams for typical
UPS installations are given in figures 9
to 15. The heavy lines represent the
cables that must be connected
(see the table in the previous chapter
for the required cross-sectional areas of
the cables).

Note:

◗ for frequency converters, the input

and output frequencies may be different
(50 or 60Hz);

◗ for frequency converters without

batteries, ignore the battery cubicles
and the + and - cables shown in the
diagram.

Special case:

The UPSs can be optionally supplied
with the neutral conductor not
interrupted by switches Q4S, Q3BP
and Q5N.
