(figures 6, 7, 8)
– 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;
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;
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
).
Fig. 5
– 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
– 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);
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);
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:
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),
