4.3. OPERATING PRINCIPLE.
This manual describes the installation and operation of SLC
TWIN RT2 series UPSs as devices that can be independently
operated or connected in parallel (for models > 3 kVA). SLC
TWIN RT2 series UPSs ensure optimum protection of any
critical load, maintaining the supply voltage of the loads
between the specified parameters without interruption during
failure, deterioration or fluctuation of mains power, and come
in a wide range of models (from 0.7 kVA to 10 kVA), enabling
the end user to select the model that best suits his needs.
Thanks to their PWM (pulse width modulation) and double-
conversion technology, SLC TWIN RT2 series UPSs are compact,
cool, silent and high performance.
The double converter principle eliminates all mains power
disturbances. A rectifier converts the AC current of the mains
into DC current, thereby maintaining optimum battery charge
level and powering the inverter, which, in turn, generates a
suitable AC sine-wave voltage for continuously powering the
loads. In the event of failure of the UPS’s mains power, the
batteries supply clean power to the inverter.
The design and construction of the SLC TWIN RT2 series UPS
has been carried out in accordance with international standards.
In addition, models with power ratings greater than 3 kVA can
be expanded with the connection of additional modules with
the same power in parallel to obtain N+X redundancy or an
increase in the system’s power.
Thus, this series has been designed to maximise the availability
of critical loads and to ensure that your business is protected
from variations in power distribution line voltage, frequency,
electrical noise, cuts and micro-cuts. This is the primary goal of
SLC TWIN RT2 series UPSs.
This manual applies to the standardised models shown in Tab. 1.
4.4. UPS OPERATING MODES.
•Normal mode.
Device running supplying output voltage from the inverter.
Mains power present with correct input voltage and
frequency.
•Battery mode.
Device running with mains voltage or frequency out of
range or without AC input power, either due to mains
failure or absence of cable connection, supplying output
voltage from the batteries.
•Bypass mode.
Device running or not, supplying output voltage directly
from the AC mains.
With the inverter running, this operating mode may be
due to an overload, blockage or inverter fault.
The actions for each incident will be as follows: Reduce
the load connected to the output, unblock the device by
resetting it – stop it and start it up again – and, if the
blockage or fault remains, contact T.S.S.
With the inverter shut down, the output supplies mains
power directly through the static bypass of the device
provided that it has AC input power.
•Frequency converter (CF) mode.
Operating mode of the UPS as a frequency converter. In
this mode, the static bypass is disabled by the condition of
disparate input and output frequencies.
Even if the LCD display on the backlit control panel
shows messages, it does not mean that the inverter is
operational. It is switched on by pressing the ‘ON’
button on the control panel, see Chapter 6.
4.4.1. Notable features.
•True on-line with double-conversion technology and output
frequency separate from the mains.
•Output power factor 1, except for B1 models where it is 0.8.
Pure sine waveform, suitable for almost all kinds of loads.
•Input power factor > 0.99 and high overall performance
(between 0.89 and 0.91 for 0.7 to 3 kVA models and > 0.93
for higher power ratings). Greater energy savings and lower
user installation costs (wiring), as well as low distortion
of the input current, which reduces pollution in the power
supply network.
•Great adaptability to the worst conditions of the mains.
Wide input voltage, frequency and waveform ranges, thus
avoiding excessive dependence on limited battery power.
•Possibility of fast and easy backup extension by adding
modules in rack format. Each battery module has two
connectors for easy connection to the device and other
identical modules.
•Availability of battery chargers of up to 6 A to reduce bat-
tery recharge times.
•N+X redundant parallel connection to increase reliability
and flexibility in power models > 3 kVA, with a maximum
of 3 devices in parallel.
•Selectable high-performance mode (ECO MODE) > 0.95 to
0.99 depending on model. Energy savings, economically
beneficial for the user.
•Possibility of starting the device without mains power
supply or discharged battery. Be careful with this aspect
because the greater the batteries are discharged, the more
the backup will be reduced.
•Intelligent battery management technology is very useful
for extending the life of accumulators and optimising
recharge times.
•Standard communication options via the RS232 serial port
or USB port.
•Digital input for device Start/Stop and ‘Error or fault’ digital
output in models with power ratings > 3 kVA.
•Remote emergency power off control (EPO).
•Control panel with LCD display available on all models and
LED indicators on devices with power ratings > 3 kVA.
•Availability of optional connectability cards to improve
communication capabilities.
•Device that can be installed as a tower or rack using the
accessories supplied. The control panel can be rotated to
adapt to either format.

4.5. OPTIONAL EXTRAS.
Depending on the configuration chosen, the device may include
any of the following options:
4.5.1. Isolation transformer:
The isolation transformer provides galvanic isolation in order
to completely isolate the output from the input and/or change
neutral mode.
The placement of an electrostatic screen between the primary
and secondary windings of the transformer provides a high
level of electrical noise attenuation.
The isolation transformer can be physically placed at the input
or output of the UPS depending on the technical conditions of
the whole system (device supply voltage and/or load voltage,
characteristics or their type, etc.).
In parallel systems, it is not possible to operate with independent
transformers for each UPS; on the contrary, it is necessary to
have a single common element for the total adequate power.
In any event, it will always be supplied as a peripheral
component external to the device itself in a separate box.
4.5.2. Exterior manual maintenance bypass.
The purpose of this option is to electrically isolate the device
from the mains and the critical loads without cutting the power
to the latter. In this way, maintenance or repair operations on
the device can be carried out without interruptions to the power
supply of the protected system, while preventing unnecessary
hazards for the technical personnel.
4.5.3. Communication card.
The UPS features a slot at the rear for inserting one of the
following communication cards.
4.5.3.1. Integration into computer networks using an SNMP
adapter.
Large computer systems based on LANs and WANs that
integrate servers in different operating systems must provide
the system manager with ease of control and administration.
This facility is obtained through an SNMP adapter, which
is universally supported by the main software and hardware
manufacturers.
Connection of the UPS to the SNMP is internal while that of
the SNMP to the computer network is made through a RJ45 10
base connector.
4.5.3.2. Modbus RS485.
Large computer systems based on LANs and WANs often
require that communication with any element that is integrated
into the computer network be made through a standard
industrial protocol.
One of the most used standard industrial protocols on the
market is the MODBUS protocol.
4.5.3.3. Interface to relays.
•The UPS has, as an option, an interface to relays card
that provides digital signals in the form of potential-free
contacts, with a maximum applicable voltage and current
of 240 V AC or 30 V DC and 1A.
•This communication port enables dialogue between the
device and other machines or devices through the relays
supplied in the terminal block arranged on the same card,
with a single common terminal for all of them.
From the factory, all contacts are normally open and can
be changed one by one, as indicated in the information
supplied with the optional extra.
•The most common use of these types of ports is to provide
the necessary information to the file-closing software.

children to avoid danger of suffocation.
Inspect the device before proceeding and, in the event
of finding damage, contact the supplier or, failing that,
our firm.
5.1.4. Transport to the site.
It is recommended to transport the UPS by means of a
pallet jack or the most appropriate method considering the
distance between the two points.
If the distance is considerable, it is recommended to
transport the device in its packaging to the installation site
and then unpack it.
5.1.5. Siting, immobilising and considerations.
•All TWIN RT2 series UPSs are designed to be mounted as
a tower model -vertical arrangement of the device- or rack
-horizontal arrangement- for installation in 19” cabinets,
regardless of whether they operate independently or as
parallel systems, whether or not they have a battery module
or whether the available backup is standard or extended
(greater number of battery modules).

5.1.5.8. Preliminary considerations before connection.
•In the description of this manual, reference is made to the
connection of terminals and switch operations that are
only available in some versions or devices with extended
backup. Ignore the related operations if your unit does not
feature them.
•Thermal control of these devices is carried out with the
passage of forced air from the front to the rear.
The front surface and about 15 cm on the rear side should
be left free of obstructions to facilitate the free circulation
of air for ventilation.
•Follow and respect the instructions described in this section
referring to the installation of a single device or a system
in parallel.
•Protection or external manual bypass board:
The system will have at least one short-circuit
protection on the UPS’s power supply line.
It is advisable to have an external manual bypass board
fitted with input, output and manual bypass protections
in single systems.
For parallel systems, it is essential to have a
distribution or manual bypass board. The board’s
circuit breakers must be able to isolate a UPS from
the system in the event of a fault and power the loads
with the others, either during periods of preventative
maintenance or during breakdown and repair.
•Upon request, we can supply an external manual bypass
board for a single device or parallel system.
You can also choose to manufacture it, taking into account
the version and configuration of the device or system
available and the documentation contained in the CD-ROM
or pen drive relating to ‘Recommended installation’.
•In the documentation supplied with this user manual
and/or on the CD-ROM or pen drive, information is
available on ‘Recommended installation’ for each input and
output configuration. This documentation includes wiring
diagrams and information about the sizes of the protections
and the minimum cross sections of cables connected to the
device according to their rated working voltage. All values
are calculated for a maximum total cable length of 30 m
between the distribution board, equipment and loads.
For longer lengths correct the cross sections to avoid
voltage drops, respecting the regulations or standards
corresponding to the country.
In the same documentation and for each configuration,
information for ‘N’ units in parallel, as well as backfeed
protection characteristics, is available.
•In parallel systems, the length and cross section of
the cables that run from the distribution or manual
bypass board to each UPS and from these to the board will
be the same for all of them without exception.
•The cross section of the cables must always be considered
in relation to the size of the terminals of the switches, so
that they are correctly fastened across their entire cross
section for optimum contact between the two elements.
•Only rated currents are printed on the nameplate of the
equipment as indicated by the EN-IEC 62040-1 safety
standard. For the calculation of the input current, the power
factor and the equipment's own performance have been
considered.
Overload conditions are considered a non-permanent
and exceptional working mode, and will not be taken
into account in the application of the protections. Do not
connect appliances or devices which may overload the UPS
to the terminals and/or outlets, such as motors.
•If peripheral input, output or bypass elements such as
transformers or autotransformers are added to the UPS or
parallel system, the currents indicated on the nameplates of
these elements must be taken into consideration in order to
use the appropriate cross sections, in compliance with local
and/or national Low Voltage Electrotechnical Regulations.
•When a galvanic isolation transformer is added to a UPS
or parallel system as an optional extra, as standard or
independently, either on the input line, at the output or
both, it must be fitted with protection against indirect
contact (differential circuit breaker) at the output of each
transformer, since, due to its own insulation properties, it
will prevent the tripping of the protections placed on the
primary of the isolation transformer in case of electric shock
on the secondary (output of the isolation transformer).
•We remind you that all the isolation transformers installed
or factory supplied, have the output neutral grounded
through a bridge between the neutral terminal and ground.
If the isolated output neutral is required, this bridge must be
removed, taking the precautions indicated in the respective
local and/or national low voltage regulations.
•This device is suitable for installation in networks
with TT, TN-S, TN-C or IT power distribution
systems, taking into account at the time of installation the
particularities of the system used and the national electrical
regulations of the destination country.
•The SLC TWIN RT2 features terminals for the installation
of an external emergency power off button (EPO) or, failing
that, a single device must be installed to cut the power
supply to the loads in any operating mode.
5.1.5.9. Preliminary considerations before connection, regarding
the batteries and their protections.
•SLC TWIN RT2 devices from 0.7 to 3 kVA incorporate the
batteries in the same box as the device, except for B0, B1
and higher power models.
•The battery protection of the device and of any accumulator
module is always by means of internal fuses that are not
accessible to the user.
USER MANUAL
18
•IMPORTANT FOR SAFETY: If batteries are installed
independently, the accumulator group must be fitted
with a bipolar circuit breaker or disconnect fuse of the size
indicated in Tab. 2.
•Inside the battery module, there are HAZARDOUS
VOLTAGES with risk of electric shock, so it is classified as a
RESTRICTED ACCESS AREA.
•Do not handle the fuse holder or battery circuit
breaker when the device is running.
•If the mains power of the device or parallel system
is cut for longer than a simple intervention and it is
expected that it will be out of service for a prolonged period
time, the system must be shut down completely.
•The battery circuit is not isolated from the input
voltage. Dangerous voltages can occur between the
terminals of the battery group and the earth. Check that
there is no input voltage before intervening on the terminals.
5.1.5.10. Connection elements.
•All of the device’s electrical connections are made from the
back of each unit:
Input and output connection.
–For models up to 3 kVA.
Input by means of a cable with plug, connectable to
the UPS through an IEC connector.
Outputs through IEC connectors.
–For models with power ratings greater than 3 kVA.
Terminals for powering the device and loads.
It is necessary to remove the transparent protective
cover to access the terminals.
Replace the cover after making the
connections to prevent possible accidents
due to direct contact, especially in tower mountings
as there is a greater risk.
Connection to batteries.
–The device and battery module have a polarised
connector.
Remove the screws and protective cover of the
connector before interconnecting it.
–All battery modules have two connectors that
enable backup extension.
Communication connectors available:
–DB9 for RS232. In models up to 3 kVA, the interface
to relays signals are supplied with the same
connector.
–USB to operate the UPS as a PC peripheral.
–Digital input and output (only in models > 3 kVA).
–For connection to external EPO button.
–Auxiliary contact for the manual bypass switch
(only in models > 3 kVA).
DB15 communication bus connectors and analogue
current signal block for connecting systems in parallel
(only in models > 3 kVA).
To access the signal block, it is necessary to remove its
protective cover.
Slot for the integration of one of the optional electronic
communication units. Remove the fixing screws and
plastic cover to enable it to be inserted.
•It is recommended to use terminals on all of the ends of
the cables connected to power terminals (input and output).
•Check that the terminal screws are correctly tightened.
5.2. CONNECTIONS.
5.2.1. Connection of the input.
•0.7 to 3 kVA models:
Take the power cable with plug and IEC connector on
the end and insert the latter into the input connector
of the UPS.
Plug the power cable into an AC power socket.
•4 to 10 kVA models:
As the device has Class I protection against
electric shock, it is essential to install a
protective earth conductor (connect earth ( )).
Connect this conductor before supplying voltage to the
input terminals.
Connect the power cables to the input terminals
respecting the order of the phase (R) and the
neutral (N) indicated on the labelling of the device and in
this manual. Pay particular attention when connecting
the power cables to the input terminals and do not
reverse the connection to the output terminals or vice
versa. Failure to respect the order will result in faults.
Where there are discrepancies between the labelling
and the instructions in this manual, labelling shall
always prevail.
In accordance with safety standard EN-IEC 62040-1, the
facility must be equipped with an automatic backfeed
protection system, such as a contactor, which prevents
the appearance of hazardous voltage or power on the
UPS input line during a mains failure (see Fig. 12).
The standard applies to both individual units and all
UPSs in parallel systems.
There can be no derivation of the line that goes
from the backfeed protection to the UPS, as this
would breach the safety standard.
Warning labels shall be affixed to all primary power
switches installed in areas remote from the equipment
to alert electrical maintenance personnel of the
presence of a UPS in the circuit.
The label shall bear the following text or an equivalent:
Before working on the circuit.
•Isolate the uninterruptible power supply system
(UPS).
•Check the voltage between all terminals, including
the protective earth.
Return voltage risk of the UPS.

For parallel systems, each device must have its own separate backfeed
protection.
Fig. 12. Backfeed protection wiring diagrams.
5.2.2. Connection to IEC connectors or output terminals.
•SLC TWIN RT2 devices feature female IEC output connectors
or terminals depending on the power of the model:
Models up to 2 kVA: 2 groups of 4 x 10A IEC
connectors identified as «OUTPUT» and «OUTPUT
PROGRAMMABLE (P1)», configurable through the
control panel and/or ViewPower.
3 kVA models: same connectors as models up to 2 kVA
and an additional 16A IEC connector.
4 to 10 kVA models: 1 group of output terminals.
In these models, a PDU (power distribution unit) is
supplied to connect to the output terminals of the
UPS. Through it, loads can be powered directly through
the two or three groups of 10 or 16 A IEC connectors
protected by a selective circuit breaker.
•Do not connect loads that in their entirety exceed
the specifications of the device, as this would cause
inconvenient cuts in the power supply of the loads
connected to the output.
•If, in addition to the more sensitive ‘critical loads’, it is
necessary to connect high-consumption inductive loads,
such as for laser printers or CRT monitors, the starting up
of these peripherals will need to be taken into account to
prevent the device from crashing.
We do not recommend connecting loads of this type due to
the amount of power they absorb from the UPS.
5.2.2.1. Connection of loads in models up to 3 kVA.
•Connect the loads to the 10 A IEC connectors.
It is important to consider the two groups of IEC
connectors available, those for ‘critical loads’ and
those for ‘non-critical loads’.
By definition, ‘critical loads’ are considered to be those
that can cause economic damage if they stop functioning
or function incorrectly.
The IEC connectors indicated in Fig. 2 as ‘non-critical
loads’ can be programmed as such through the control
panel. In this case, the backup of the batteries for the
loads connected to the IEC connectors indicated in Fig. 2 as
‘critical loads’ will be reserved. Take into account that they
are set by default as ‘critical loads’.
•The 3 kVA models also have a 16A IEC connector
that enables the connection of a load of the total
power of the device.
5.2.2.2. Connection of loads in 4 to 10 kVA 10 kVA.
•As the device has Class I protection against electric
shock, it is essential to install a protective earth
conductor (connect earth ( )). Connect this conductor
before supplying voltage to the input terminals.
•Connect the loads to output terminals U (L) and N,
respecting the order of the phase and the neutral
indicated on the labelling of the device and in this manual
(see Fig. 2). Where there are discrepancies between the
labelling and the instructions in this manual, labelling shall
always prevail.
•Together with the device, a PDU with several 10 and 16A
IEC output connectors with their respective circuit breaker
is supplied.
When the utility of the PDU is required to power the loads,
it will be necessary to connect its input cables to the output
of the UPS, respecting the following assignment:
Black or brown cable to phase U (L).
Red or blue cable to neutral (N).
Green-yellow cable to earth terminal ( ).
•
With regard to the protection that must be placed at the
output of the UPS when the PDU is not used, we recommend
distributing the output power over at least four lines. Each of
them will have a circuit breaker with a value of one quarter
of the rated power. This type of output power distribution
will allow that in the event of a fault in any of the machines
connected to the equipment, which provokes a short circuit,
does not affect more than the line that is broken.
The remaining connected loads will have continuity
assured due to the tripping of the protection, only in the
line affected by the short circuit.
5.2.3. Connection to external batteries (backup extension).
•Failure to comply with the instructions in this
section and Safety Instructions EK266*08 car-
ries a high risk of electric shock and even death.
•SLC TWIN RT2 devices from 0.7 to 3 kVA incorporate the
batteries in the same box as the device, except for B0, B1
and higher power models.
•The battery protection of the device and of any accumulator
module is always by means of internal fuses that are not
accessible to the user.
•IMPORTANT FOR SAFETY: If batteries are installed
independently, the accumulator group must be fitted
with a bipolar circuit breaker or disconnect fuse of the size
indicated in Tab. 2.

Tab. 2. Protection features between device and battery
module.
•Before starting the connection process between
battery module or modules and device, check that
the device and loads are ‘Off’.
Also, when the batteries are installed by the user
independently, the protection fuse or isolator must be
deactivated.
•Connection of the battery module to the device is made by
means of a cable featuring polarised connectors at both
ends, which is supplied with the first one. Two connectors
are available for this purpose on the device and battery
module.
Similarly, the battery modules feature two connectors that
allow the linking of modules in parallel.
•Each battery module is independent for each device.
Two devices must not be connected to the
same battery module.
Likewise, in parallel systems (4 to 10 kVA models), with
each device connected to its battery module or modules,
they should be considered as single devices that are
independent of each other.
•Fig. 13 shows the connection of a 10 kVA device in a
rack arrangement with two battery modules. For a larger
number, proceed in a manner similar to those shown in the
illustration.
Fig. 13. Connection to battery modules.
5.2.4. Connection of the input earth terminal ( ) and the
earth connection terminal ( ) .
•As the device has Class I protection against electric
shock, it is essential to install a protective earth
conductor (connect earth ( )). Connect this conductor
before supplying voltage to the input terminals.
•
Make sure that all of the loads connected to the UPS are only
connected to its earth connection terminal ( ). Failure to
limit the earthing of the load or loads and battery module or
modules to this single point will create earth return loops
that will degrade the quality of the power supplied.
•All terminals identified as an earth connection ( ) are
connected to each other, to the earth terminal ( ) and to
the device’s earth.
5.2.5. Terminals for EPO (emergency power off).
•The UPSs have two terminals for the installation of an
external emergency power off (EPO) output button.
•The device is dispatched from the factory with its EPO
circuit set to closed (NC) by default. In other words, the
UPS will cut the output power supply, emergency power
off, when the circuit is opened:
Either by removing the female connector from the socket
where it is inserted. This connector has a cable connected
as a jumper that closes the circuit (see Fig. 14-A).
Or by pressing the button external to the device
belonging to the user installed between the terminals
of the connector (see Fig. 14-B). The connection on the
button must be in the normally closed contact (NC), so
it will open the circuit when activated.
The reverse functionality can be selected through the
communications software and control panel.
Except for specific cases, we advise against this type
of connection in view of the purpose of the EPO button,
since it will not act upon an emergency request if either
of the two cables that run from the button to the UPS is
accidentally cut.
By contrast, this anomaly would immediately be detected
in a closed EPO circuit, with the inconvenience of an
unexpected cut in the powering of the loads, but a
guarantee of effective emergency functionality.
•To recover the normal operating state of the UPS, it is
necessary to insert the connector with the jumper in its
receptacle or deactivate the EPO button. The device will
be operational.
