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.

Installation

(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),

◗ 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.

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.
