4.3.1. Introduction.
The SLC ADAPT X series UPS basically consists of:
•
Subrack with 2, 4 or 6 slots to install the power modules.
•
Power modules, consisting of the following blocks:
PCF-Rectifier-AC/DC-.
Battery charger.
Inverter -DC/AC-.
Digital control and UPS management.
•
Centralized bypass module: control of UPS and parallel pa-
rameters.
•
Maintenance bypass
•
Control panel with touch screen (see section 7 for more in-
formation).
•
Batteries (Quantity, type and location depending on the
back-up time).
4.3.2. Architecture.
4.3.2.1. Structural diagram.
Fig. 4 shows a single-line diagram of the equipment with three-
phase input and output, as an example.
All subrack units are structured according to the same criteria,
separate power supply for the PFC-rectifier and static bypass.
However, unless otherwise requested, separate grids, origi-
nally from the factory will connect the terminals of the phases
of both blocks by means of the copper rods in order to have a
single common input.
When separate power supplies are required, it is man-
datory to remove the copper rods between phases of
both blocks before connecting the power cables,
leaving the one for the neutral terminals.

The batteries are represented in
the structural scheme as they are
an essential part of any UPS,
although they will never be
included in the sub-rack itself. The
batteries can be supplied in the
same rack cabinet in which the
ADAPT subrack is assembled, in a
separate cabinet, on a rack or
when the customer does not have
them available, not supply them
at all.
