Note as regards to the batteries:
Acronyms B0 and B1 stated in the nomenclature is related to
the batteries:
B0 Equipment without batteries and with the necessary acces-
sories to install the batteries.
Batteries owned by the client will be installed out from
the case or cabinet of the UPS.
B1 Equipment with extra battery charger. The equip-
ment is supplied without batteries and no accessories
(screws and electrical cables), corresponding to the
specific batteries in the model.
Under request is possible to supply the accessories
(screws and electrical cables), needed to install and
connect the batteries.
For equipments requested with no batteries, the acquisition and
connection of them will always be done by the customer and
under his responsibility.
Data related to batteries about quantity, capacity and voltage
are stated in the battery label sticked beside the nameplate of
the equipment, respect strictly these data and connection po-
larity of the batteries.
4.3. OPERATING PRINCIPLE.
This manual describes the installation and operating of the Uninter-
ruptible Power Supply [UPS] from SLC TWIN PRO2 series as equip-
ments that can run as a complete separate and independent units.
UPSs from SLC TWIN PRO2 series assures an optimal protection for
any critical load, keeping the power supply of the loads between
the stated parameters, with no break, during any blackout, or mains
fluctuations or deteriorations with a wide range of available models
(from 0.7 kVA to 3 kVA), it allows adapting the model to the end-user
needs.
Thanks to the used technology, PWM (Pulse Width Modulation) and
double conversion, the UPSs from SLC TWIN PRO2 series are com-
pact, silent, and with high efficiency.
The double conversion principle cancels all the AC mains pertur-
bations. A rectifier converts the alternating current from AC input
mains into DC direct current, that keeps at the optimal level the bat-
teries and supplies the inverter, which at the same time generates
an AC voltage ready to feed the loads permanently. In case of fault
of the input power supply of the UPS, the batteries supplies clean
energy to the inverter.

4.4. OPTIONS.
Depending on the selected configuration, the equipment can include
any of the following options:
4.4.1. Isolation transformer.
The isolation transformer, provides a galvanic isolation that allows
isolating the output from the input completely.
The installation of an electrostatic shield between the primary and
secondary windings of the transformer provides a high level of at-
tenuation of the electrical noises.
The isolation transformer can be installed at the input or output of
the UPS from SLC TWIN PRO2 series and it will always be located
out from the equipment enclosure.
4.4.2. External maintenance manual bypass.
The purpose of this option is to isolate electrically the equipment
from mains and critical loads, without breaking the power supply to
the loads. Therefore, in this way the maintenance or fixing tasks can
be done in the equipment with no interruption on the power supply
energy to the protected system, at the same time that unnecessary
risks are avoided to the technical staff, because it allows a complete
disconnection of the UPS from the installation.
4.4.3. Integration in IT networks by means of the SNMP adaptor.
The big IT systems based on LANs and WANs that integrate servers
with different platforms, they have to include an easy way of con-
trolling and managemet at the manager system disposal. This fa-
cility is got through the SNMP adaptor, which is well-known by the
main software and hardware manufacturers.
The available SNMP option for SLC TWIN PRO2 series is a card to be
inserted into the slot that the UPS has in its rear side.
The connection of the UPS with the SNMP is internal meanwhile the
connection between the SNMP and the IT network is done through a
RJ45 connector 10 base.
4.4.4. MODBUS protocol.
The big IT systems based on LANs and WANs, many times they re-
quire that the communication with any device to be integrated in
the IT network has to be done by means of an industrial standard
protocol.
One of the most used industrial standard protocols in the market is
the MODBUS protocol. SLC TWIN PRO2 series is also ready to be
integrated in this type of environments through the external “SNMP
TH card” device with MODBUS protocol.

5. INSTALLATION.
•Check the Safety instructions (see chapter 2).
•Check that the data in the nameplate are the required by the
installation.
•A wrong connection or manoeuvring, can make faults in the UPS and/
or loads connected to itself. Read carefully the instructions of this
manual and follow the stated steps in the established order.
•The equipments can be installed and used by personnel
with no specific training just with the help of this
«Manual» only, less those ones that are hard wired, which have
to be installed by qualified personnel.
•All connections of the equipment including the control
(interface, remote panel, ...), will be done with the
switches at rest and no voltage present (UPS power supply
switch to «Off»).
•Never forget that the UPS is an electrical energy gener-
ator, so the user has to take the needed cautions against
direct and indirect contacts.
•Battery circuit is not isolated from input voltage. Haz-
ardous voltages can be found out between the battery
terminals and earth. Check that there is not input voltage before
doing any intervention on them.
5.1. TO BE CONSIDERED IN THE INSTALLATION.
•All the equipments have power cord with schuko plug to be con-
nected to the AC mains, less the B1 version of 3 kVA, which is
hard wired.
In the same way, 2 or 3 schuko outlets are supplied depending
on the model, for its connection with the loads [output] and also
to the terminals in all the 3kVA units.
For the rest of connections is used an connector for the battery
connection [B1 version] and ports for communications.
•Cross cable section of the input and output lines, will be calculated
from the currents stated in the nameplate of each equipment, and
respecting the Local and/or National Low Voltage Electrotechnical
Regulations.
•Protections of the switchgear panel, will have the following fea-
tures:
For input line, type B for RCD devices and C characteristic
for circuit breakers.
For the output (load feeding), C characteristic for circuit breaker.
Regarding the size, they will be as minimum to the currents
stated in the nameplate of each UPS.
•In the nameplate of the equipment there are only printed the
nominal currents as it is stated in the safety standard EN-IEC
62040-1. To calculate the input current, the power factor and the
efficiency of the equipment have been considered.
Overload conditions are considered as nonpermanent and ex-
ceptional operating mode.
•If it is added peripherals to the input or output like transformers
or autotransformers to the UPS, the currents stated in the own
nameplates of those elements has to be considered in order to
use the suitable cross sections, by respecting the Local and/or
National Low Voltage Regulation.
•When an equipment incorporates a galvanic isolation
transformer, as standard, as an option or either installed
by yourself, either at the UPS input line, output or in both, pro-
tections against indirect contact has to be fitted in (residual cur-
rent device) at the output of each transformer, because due to its
specification of isolation it will prevent the triggering of the
protections fitted in the primary of the transformer in case of
electrical shock in the secondary (output of the isolation trans-
former)
•Remind you that all external isolation transformers already in-
stalled or supplied from factory, has the neutral of the secondary
connected to earth by means of a cable bridge between both
terminals. If it were required an isolated output neutral, remove
this cable bridge, keeping the precautions stated in the respec-
tive local and/or national low voltage regulations.
•All standard UPSs have batteries in the same enclosure of the
equipment , less those ones as B1. In the first ones, the battery
protection is by internal fuses and there is no access to the end-
user.
Also the battery modules have internal protections by fuses and
in the same way as it is done in the own equipments, they are
not accessible by the end-user.
•IMPORTANT FOR SAFETY: In case of installing the bat-
teries by yourself, the accumulators have to be provided
with a two pole circuit breaker protection sized to the features
stated in table 2.
5.2. RECEPTION OF THE EQUIPMENT.
5.2.1. Unpacking, content checking and inspection.
•To unpacking, see section 5.2.3.
•On receiving the device, make sure that it has not suffered any
damage in transport (impact, drop, ...) and its features correspond
with the ones in the order, so it is recommended to unpack the
UPS and make a first visual inspection.
•In case of observing damages, make all pertinent claims to the
transport agency or in their lack to our company.
Never start up an equipment when external damages
can be observed.
•Also check that the data in the nameplate sticked in the pack-
aging and in the equipment, correspond to the ones stated in
the order, so it is required to unpack it (see section 5.2.3). Other-
wise, make a nonconformity as soon as possible, by quoting the
serial number of the equipment and references in the delivery note.
•Check the contents of the packaging. Depending on what we are
checking, an equipment or battery module, the contents will vary.
UPS:
–The own equipment.
–Hardcopy quick guide. Also for 3kVA models, a user’s
manual on digital support [CD].
–1 connection cable for input - schuko plug and IEC con-
nector -.
–1 USB communication cable.
–1 female connector for connection of an external EPO,
with an isolated cable as jumper mode in order to close
the circuit.
Battery module:
–The own module.
•Once the reception is finished, it is advisable to pack the UPS
again till its commissioning in order to protect it against me-

5.2.2. Storage.
•Storage of the equipment will be done in a dry place, safeguard
from rain, protected from dust, water jets or chemical agents,
never outdoors. It is advisable to keep the equipment and the bat-
tery pack/s, into their original packages, which have been designed
to assure the maximum protection during the transport and storage.
•In equipments that include Pb-Ca batteries, the figures,
stated in table 2 of the EK266*08 document, of charge
period time depending on the temperature that they are ex-
posed, must be respected, otherwise the warranty will be in-
validated.
•After this time, connect the equipment to mains and together
with battery unit, if any, start it up according to the instructions
described in this manual and charge them for 12 hours.
•Finally, shutdown the equipment, disconnect it and fit the UPS
and batteries in their original packaging, noting the new battery
charge date on each respective label.
•Do not store the devices where the ambient temperature exceeds
above 50ºC or below –15ºC, otherwise it may degrade the electrical
characteristics of the batteries.
5.2.3. Unpacking.
•The packaging of the equipment has a cardboard enclosure, expanded
polystyrene [EPS] or polyethylene foam [EPE] corners, plastic bag and
polyethylene strip, all materials a re recyclable; so if you are going to
dispose them, do it in accordance with the regulations in force. It is
recommended to keep the packaging in case it were needed in future.
•Proceed as follows:
Cut the strips of the cardboard enclosure, in those models
with strips.
Take out the accessories (cables, documentation, ... )
Take out the equipment or battery module from the pack-
aging, considering the help of a second person depending
on the weight of the model.
Remove the protection corners of the packaging and the
plastic bag.
Keep out of reach of children the plastic bag, due to
the risks that it involves.
Inspect the equipment before continuing and in case dam-
ages are confirmed, contact with the supplier or in lack of
him with out firm.
5.2.4. Transport to location.
•Although the weight of the equipments is not so high, it is rec-
ommended to move the UPS by the use of a forklift, pallet truck
or by means of the most suitable means of transport by evalu-
ating the remoteness of the location point.
If the distance is high, it is recommended to move the equipment
still packaged till the installation place and unpack it later.
5.3. CONNECTION.
•Cross cable section used in the power supply of the
equipment and loads to feed, will be sized according to
the nominal current stated in the nameplate sticked on the
equipment, by respecting the Low Voltage Electrotechnical Reg-
ulations or norms of the corresponding country.
•Installation will have the suitable input protections sized to the
current of the equipment and stated in the nameplate of the
equipment (residual current devices type B and circuit breaker
with C characteristic or any other equivalent one).
Overload conditions are considered as a nonpermanent an ex-
ceptional operating mode, so these currents will not be kept in
mind when sizing the protections.
•Output protection will be done with a circuit breaker of C char-
acteristic or any other equivalent one.
•The equipments can be installed and used by personnel
with not specific training, just with only help of this
«Manual», less those ones with power blocks have to be in-
stalled by qualified personnel.
•In the hard wired models, is needed to remove the fixing screws
of the protection cover and the own cover, to proceed to the
parallel connection.
When finalising the corresponding tasks the cover/s and their
fixing screws will be fitted back.
•To insert the option cards, it is needed to remove the fixing
screws of the smart slot and the own cover.
When finalising the corresponding tasks the cover/s and their
fixing screws will be fitted back.
•It is recommended to use pointed terminals in all ends of the
cables connected to the power blocks (input and output).
•Check the correct torque in the screws of the power blocks.
5.3.1. Connection of input.
•As this is a device with class I protection against electric
shocks, it is essential to install a protective earth con-
ductor (connect earth ). Connect the conductor to the ter-
minal, before connecting the power supply to the input UPS.
•Equipments with IEC inlet (all models less the B1 version of
3kVA):
Toke the power cord with schuko plug and IEC connector.
Connect the IEC connector to the UPS inlet.
Insert the schuko plug in to the wall AC outlet.
•In equipments with terminal blocks (3 kVA model B1).
Connect the power supply cables to input power blocks R (L) and
N, by respecting the rotation of phase and neutral stated in
the labelling of the equipment and in this manual. If this rotation
is not respected there could be fault/s and/or anomalies.
Pay attention to the correct connection of the input ter-
minals, including the earth, by observing the labelling of
the equipment.
When discrepancies exist between the labelling and the instruc-
tions of this manual, the labelling will always prevail.

Tab. 2. Features of protection between the equipment and
battery cabinet.
•Before starting the connection between the bat-
tery module/s and the equipment, check that the
equipment switch/es and the one in the battery cabinet
are in “Off” position.
Likewise when batteries are installed by own self, the fuse or
switch has to be turned off.
•Connection terminals of external batteries with the equipment
are done with a polarised connector. This connector is not avail-
able on standard models.
•To connect the equipment with the battery module, use the
cable trunk supplied with the module and connect it between
both units and through the connectors.
When more than one battery module is supplied for one equipment, the
connection among the modules will be done through the cable trunk sup-
plied in the second battery module.
Figure 11 shows as an example, the connection of a SLC-TWIN
PRO2 B1 with "n" battery modules. Less the rear view of the
model, it is applicable to all the range stated in this manual.
Connect the available modules depending on each case.
•If for any reason the end-user manufactures the battery cable trunk,
the colour code of the cables has to be respected, red for positive,
black for negative and green-yellow for earth, as well as the correla-
tion of the connection (+ with +, – with – and with ).
UPS Module 1 Module “n”
Fig. 11. Connection among the equipment and "n" battery
modules.
•Each battery module is independent for each equipment.
It is strictly prohibited to connect two equipments
to one battery module.
5.3.2. Connection to output.
•As this is a device with class I protection against electric
shocks, it is essential to install a protective earth con-
ductor (connect earth ). Connect the conductor to the ter-
minal, before connecting the power supply to the input UPS.
•All the equipments have «N» schuko outlets or IEC connectors
depending on the model.
Also in the 3kVA B1 with output connectors IEC equipments,
there is a group of output terminals.
Loads can be connected to the IEC connectors to the
output terminals or to both at the same time, provided
that the power of the equipment is not exceeded, otherwise
there could be sudden breaks in the power supply to the loads
connected to the output.
•Connect the loads to the outlets schuko, IEC connectors or ter-
minals.
•In models with terminal blocks, connect the loads to output
power block U (L) and N, by respecting the phase and neutral
rotation stated in the labelling of the equipment.
When discrepancies exist between the labelling and the instruc-
tions of this manual, the labelling will always prevail.
•If besides of the critical loads, it is required to connect lagging
loads of high consumption, like laser printers or CRT monitors,
the inrush currents of these peripherals will be kept in mind in
order to avoid blocking the equipment under the worst condi-
tions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.
•With respect to the protection that must be placed at the output
of the UPS, we recommend that the output power should be
distributed in at least four lines. Each one should have a cir-
cuit breaker protection switch of a value of one quarter of the
nominal power. This type of power distribution will allow that in
the event of a breakdown in any of the machines connected to
the device causing a short-circuit, it will affect to no more than
the line that is faulty.
The rest of the connected loads will have their continuity as-
sured due to the triggering of the protection, because the line
affected by the short-circuit will trip its protection.
5.3.3. Connection of external batteries [extended back up
times] -B1-.
•To not respect the stated indications in the safety
instructions EK266*08 means a high risk of elec-
trical discharge and even the death.
•All the standard UPSs have batteries in the same enclosure, less
the B1. Battery protection is done by internal fuses and not ac-
cessible for the end-user.
Battery modules have internal protections for the batteries too
and they are not accessible for the end-user.
•IMPORTANT FOR SAFETY: In case of installing the bat-
teries by yourself, the accumulators has to be provided
with a two pole circuit breaker protection sized to the features
stated in table 2.

5.3.4. Connection of main input earth terminal and the earth
bonding terminal .
•As this is a device with class I protection against electric
shocks, it is essential to install a protective earth con-
ductor (connect earth ). Connect the conductor to the ter-
minal, before connecting the power supply to the input UPS.
•Make sure that all the loads connected to the UPS are only con-
nected to the protective earth bonding terminal . The fact
of not restricting the earthing of the load or loads and/or the
batteries case/s or cabinet/s to this single point will create a
return loops to earth which will affect the quality of the supplied
power .
•All terminals identified as earth bonding , are joined to-
gether, to the main protective earthing terminal and to the
frame of the device.
5.3.5. Terminals for EPO (Emergency Power Off).
•All UPSs have a terminal strip to install an external button, for
Emergency Power Off [EPO].
•The equipment is preset from factory with the EPO as normally
closed contact [NC]. So, the UPS will break the output power
supply when the circuit is open:
Either by removing the female connector inserted in the plinth.
This connector has a cable bridge to close the circuit [Fig. A].
Fig. A Fig. B
Or by turning on the external button installed and belonging
to the end-user. The connection in the button has to be
in normally closed because it will open the circuit when
turning it on.
•Through the control panel, it can be selected the reverse func-
tionality (Password required), normally open [NO].
Less punctual cases, it is not recommended to use this type of
connection due to the function of the EPO button, because it
would not work in case of any of the two cables that goes from
the button to the UPS were cut [damaged].
On the other hand this failure would be immediately detected
in the normally closed EPO type, with the inconvenience of the
sudden break in the power supply to the loads, but with a com-
plete guarantee of the functioning of the emergency power off.
•To restore the normal operating mode of the UPS, the connector
with the cable bridge has to be fitted back in the terminal strip
or to deactivate the EPO button and later on to cancel the EPO
status in the control panel . The equipment will be operative.
5.3.6. Communication ports.
5.3.6.1. USB interface.
•The USB interface provides the “smart battery” feature which
supports the HID (Human Interface Device) Power Device Class,
no software installation is required. Windows/Linux/Mac Op-
erating Systems come with an embedded power management
and monitoring function. When that computer is connected to
the UPS via the USB interface, the UPS will be automatically
acknowledged by the OS as a “HID UPS Battery”, and the user
will be able to set action to make when the low battery alarm
is triggered, like shutdown the computer automatically. Also,
the UPS with this feature is the ideal back-up power for NAS
(Network-Attached Storage).
•Communication line (COM) is a very low voltage circuit
of safety. To preserve the quality, it has to be installed
separate from other lines that have dangerous voltages (energy
distribution line).
•USB interface is used by the monitoring software and firmware
updating.
•USB communication port is compatible with the USB 1.1 pro-
tocol for communication software.
5.3.6.2. Smart slot.
•UPSs have a unique slot, hidden rear the cover stated in the
views of the equipment as “Smart slot”, and allows inserting
any of the following options cards:
SNMP for control via Web.
Remote UPS management through Internet or Intranet.
Relays interface. It owns isolated dry contact relay outputs
for UPS status: such as Mains/Utility failure, Battery low,
UPS alarm/OK, or on Bypass and so on. To see more detail
about the interface definitions please check the AS400 user
manual.
Modbus. It provides the Modbus protocol through a
standard RS485 port. For more information, please check
the CMC user manual.
•For more information, contact with our S.T.S or our nearest dis-
tributor.
5.3.7. Software.
•Free software download - WinPower.
WinPower is a UPS monitoring software, which makes a user-
friendly interface of monitoring and management. This software
supplies an auto Shutdown for a system based on several PCs
in case of an electrical blackout. With this software, the end-
users can monitor and manage any UPS in the same IT network,
through the RS232 or USB communication port, never mind the
distance between them.

5.3.8. Considerations before starting up the connected loads.
•It is recommended to charge the batteries for 12 hours as
minimum before using the UPS for first time. When sup-
plying voltage to the equipment, the battery charger will auto-
matically work.
•[B1] equipments with extended back up time has a bat-
tery charger with higher quality performances. It is rec-
ommended to charge the batteries for 12 hours as minimum
before using the UPS for first time.
•Nevertheless, those equipments with extended back up
time and with no additional battery charger, it is recom-
mended to charge the batteries of each battery module for 12
hours.
•Although the equipment can work without charging the bat-
teries during the stated time without any problem, the risk of a
long blackout has to be valued during the first operating hours
and the available autonomy time in the UPS.
•Do not start up the equipment and loads completely till chapter
6 states it.
Nevertheless, when it is done, it will be done gradually to avoid
any problem, as minimum in the first commissioning.
•If inductive loads with big inrush current apart from sensitive
ones are required to be connected like laser printers or CRT
monitors, keep in mind the start inrush currents of these pe-
ripherals in order to avoid that the equipment becomes blocked
under the worst conditions.
It is better to not connect the loads of this kind, due to the high
quantity of energy resources that take from the UPS.

6. OPERATING.
6.1. UPS COMMISSIONING AND SHUTDOWN.
6.1.1. Preliminary controls.
•Make sure that all connections have been done properly, and
respecting the labelling of the equipment and the instructions
of chapter 5.
•Check that the power supply is correct.
•Check that the UPS is Off [shutdown].
•Make sure that all loads are shutdown «OFF».
Loads can be connected after the UPS start up and one
by one. Before shutdown the UPS, check that all loads
are shutdown.
•Check that the thermal protection of the equipment is not
tripped.
•It is very important to proceed in the established order.
•For UPS views, see figures 1 to 10.
•Turn «ON» the protection of the distribution panel.
6.1.2. Start up the UPS, with AC mains.
•The UPS can’t supply voltage to the loads because the bypass
mode is deactivated, code «STbY».
•To start up the UPS, press over the key «ON» of front panel for
more than 1 second, the inverter will start up and at the same
time the status of the UPS will be displayed in the LCD of the
front panel.
•Start up the load/s, do not overload the UPS.
6.1.3. Start up the UPS, with no AC mains (Battery mode)
•To start up the equipment with no AC mains -cold start-, it is
needed to press twice the key «ON» from front panel consecu-
tively, keeping pressed the key in the second pulsation for more
than 1 second. The inverter will start up and at the same time
the status of the UPS will be displayed in the LCD of the front
panel.
In case of mains fault with the loads connected and turned on,
the time that the UPS will be working, will depend on the battery
charge level and the consumption of the own loads connected
to the output.
•Start up the load/s, do not overload the UPS.
6.1.4. UPS shutdown with AC mains (on Inverter mode).
•To shutdown the inverter of UPS, press over the key «OFF» of
front panel for more than 1 second.
The UPS will shift to no output mode «STbY» -bypass deacti-
vated- «STbY» or bypass mode «BYPA», depending if the initial
configuration has been changed or not.
On bypass mode «bYPA», the UPS will still be supplying output
voltage through its bypass, so to shutdown the loads com-
pletely, the circuit breaker switch from control panel will have
to be turned off too.
6.1.5. UPS shutdown with no AC mains [on Battery mode].
•Shutdown the UPS inverter by a simple pulsation of more than 1
second over the key «OFF». The UPS will be shutdown.
If the factory preset setting has been changed from
STbY». to «bYPA», when mains voltage is restored the equip-
ment will still be supplying voltage to the output through the
bypass. It is needed to turn the circuit breaker switch from control
panel off, in order to leave the loads with no voltage.
6.1.6. Battery test function.
•To make a battery test with the equipment started up and mains present,
press over the button «ON» of the front panel for more than 1 second, the
test will start automatically.
•It is possible to make the same battery test in the same conditions, but
with no AC mains. It is not recommended, because depending on the
status of the batteries and load level connected at the output, there
could be a break in the power supply, which would mean a fault in the
load power supply.
•With this test, it is able to detect if the batteries are low, open or not
connected. It is possible to automate this test periodically by setting the
time to the required by the end-user.
6.1.7. Alarm silencer.
•The acoustic alarm is activated when the equipment works on battery
mode. If it disturbs, it can be silenced by pressing for more than 1 second
the key «ON»/«MUTE».
The alarm will be automatically activated again due to low bat-
tery (end of back up time). When it happens, loads and UPS have
to de shutdown, because the equipment will break the output
voltage in short.
•If the alarm on bypass mode disturbs, press the key «ON»/«MUTE»
for more than 1 second to deactivate it. This action will not affect
to the warning and/or alarm fault.
6.1.8. EPO (Emergency Power Output).
•Also it is know as RPO (Remote Power Output).
Check that the connector of Fig. A is inserted, before pro-
ceeding with the start up.
When it is activated, the output of the equipment doesn’t supply
voltage and the screen of the LCD panel shows the «EPO». The
EPO acronym are displayed in the screen of the LCD panel in-
stead of the output voltage figure.
It is a special situation, where it is done an immediate break
of the UPS output voltage and alarms, as a preventive or emer-
gency measures.
The EPO condition leaves the loads with no power supply, but
the UPS is not shutdown. To do it, the EPO condition has to be
released previously and then shutdown the equipment through
the key «OFF» (see table 3). To start up the UPS press over the
key «ON» (see table 3).
