4.4. UPS DESCRIPTION.
4.4.1. General description and block diagram.
The
SLC CUBE4
unit is a double conversion online Uninterrupt-
ible Power Supply (UPS). The classification in terms of its per-
formance is in accordance with the UPS international standard
(IEC 62040-3), corresponding to "VFI-SS-11"
The UPS achieves maximum performance in terms of efficiency,
reliability, availability and adaptability to the needs of every instal-
lation, thanks to its advanced design:
Control based on 2 DSP (Digital Signal Processor) cores for the
•
PFC and the Inverter, and two microcontrollers for the display
and communications.
Rectifier and inverter with 3 switching levels.
•
State-of-the-art electronic switching devices.
•
Compact mechanical design optimised for maintenance.
•
Advanced control techniques for achieving the best electrical
•
performance.
Parallel system of up to 4 units.

The unit is supplied without batteries and without accessories (screws and electric cables).
The batteries are expected to be installed in an external cabinet or battery rack. Upon request,
the cabinet or rack and the necessary accessories can be supplied.
For units ordered without batteries, their purchase, installation and connection will always be borne
under their
by the customer and
the necessary installation and connection work may be necessary. The data related to the batteries in
terms of number, capacity and voltage are indicated on the battery label next to the unit's name plate.
Adhere strictly
to these data and the polarity of the battery connection.
On units with a separate static bypass line, a galvanic insulation isolation transformer must be in-
serted in either of the two UPS power lines (rectifier or static bypass input), to prevent the direct
connection of the neutral of the two lines via the unit's internal connections. This only applies when
the two power lines come from two different networks, such as:
- Two different electricity companies.

"VFI" ("Voltage Frequency Independent"), indicates that the output voltage and frequency
of the UPS are independent of the input voltage and frequency.
"SS" (sinusoidal-sinusoidal): sinusoidal output voltage both in normal and battery mode.
(See chapter 4.5. of this manual)
"11" (dynamic response classification "1", see. IEC 62040-3): both in operating mode
changes, as well as in linear load steps, the dynamic response is the best possible
(response speed, voltage drop) within the classification specified by the standard in
question..
