• Never forget that the UPS is a generator of electrical
energy, therefore the user has to take precautions
about against direct and indirect contacts.
•
Its energy source, a part from the AC mains, lies on the batteries, usually included in the same case or cabinet that the equipment electronics. However, some models and/or extended back up times, batteries can be supplied in a separate case or cabinet.
If the batteries are connected to the equipment and their protections are switched “On”, whenever they are, it is irrelevant if the UPS is or not connected to mains, as well as the status of the mains protection. The outlets or output power blocks will supply voltage meanwhile the battery set has energy.

•
If the instructions are not in total or partial and in special referred to the safety, do not carry on with
the installation or commissioning tasks, because there could be a risk on your safety or on the other/s persons, being able to make serious injuries even the death, also it can cause damages to the equipment and/or to the loads
and installation.
The local electrical regulations and the different restrictions of the client's site, they can invalidate some recommendations included in the manuals. When discrepancies exist, the user has to comply the local regulations.
The equipments provided with power cord with plug and outlets, can be connected and used by personnel without any kind of experience.
The equipments with power blocks have to be installed by
qualified personnel and it can be used by personnel with not specific training, just with only help of this manual.
A person is defined as qualified, if it has experience of assembling, commissioning and perfect control operating of the equipment, if he has the requirements to do the job and if has read and understand all the things described in this manual, in particular the safety indications. Such preparation is considered only valid if it is certified by our S.T.S..
• Place the equipment the closest to the power supply and loads to be supplied, leaving an easy access if it were needed an urgent disconnection.
In the hardwired equipments and due to the impossibility of fast disconnection, a diconnection device (switch) with easy access and close to the equipment will be installed.
• Warning labels should be placed on all primary power switches installed in places away from the equipment to alert the electrical maintenance personnel of the presence of a
UPS in the circuit
The label will bear the following text or an equivalent one:
Before working in this circuit.
• Isolate the Uninterruptible Power System (UPS).
• Check the voltage between all terminals including the protective earth.
Risk of voltage feedback from UPS.
1.2.3.1. General safety warnings.
• All connections and disconnections of the cables from the equipment, including the control ones, will be done with no power supply and the switches on rest, position «O» or «Off».
• Shutdown the equipment completely by switching «Off» the button of the control panel first. Next disconnect the cable from the wall outlet for equipments up to 3 kVA or by switching «Off» the input circuit breaker and disconnect the power supply cables in models with higher power rate.
The indiscriminate manoeuvring of the switches may involve production losses and/or equipment damages. Consult the documentation before doing any action
• Pay special attention to the labelling of the equipment that warns about the «Electrical shock hazard». Inside the equipment there are dangerous voltages, never open the enclosure, the access has to be done by qualified staff. In case of maintenance or fault, consult to the closest ( S.T.S.).
• Cross cable sections used to supply the equipment and loads, will be according to the nominal current stated in the nameplate label of the equipment, and respecting the Low Voltage Electrotechnical Regulations or standards of the country.
•
Use approved cables only
Protection Earth cable of the UPS drives the leakage current of the load devices. An isolated earth cable has to be installed as part of the circuit that supplies the equipment. Cross cable section and its features will be same as the power supply cables, but with green colour with or without the yellow strip.
All outlets of the UPS has an earth bonding, duly connected and those equipments with power blocks there is an exclusive terminal for the load earth connection. When an outgoing distribution is done, i.e power strips, it is essential that they have an earth terminal connected to each one of them.
It is essential that the cables that supplies the loads have the earth connection cable.
The protection earth must be connected to the frame or metallic chassis of any electrical equipment (in our case to the UPS, battery cabinet or case and loads), assuring that it is done before connecting the input voltage.
• For the smallest devices (the ones connected with the foreseen power cord with plug), the user has to check the wall outlet corresponds with the type of supplied plug, with earth duly installed and connected to the local protection earth.
•
Check the quality and availability of the earth, it has to be between the defined parameters by the local or national regulations.
During the normal UPS operation, in equipments up to
3kVA the power cord cable can't be disconnected from wall outlet, because the protection earth of the own UPS would be disconnected and also the earth from the loads connected to the output.
For this reason, the general protection earth cable of the building or switchgear panel that supplies the UPS will not be disconnected.
• In small equipments check that the sum of the leakage currents of the UPS and connected load/s do not exceed over
3,5mA.
• The installation will have input protections sized to the currents of the equipment and stated in the nameplate label
(RCD devices type B and circuit breakers with C characteristic or any other equivalent one).
For equipments with three phase input, and connected to an IT distribution system, the protection will be four poles in order to break the three phases and neutral in the same manoeuvring.
Overload conditions are considered as a nonpermanent an exceptional operating mode, so these currents will not be kept in mind when sizing the protections.
• Do not overload the UPS by connecting loads with inrush consumptions at its output, like laser printers.
• For those installations with redundant equipments or separate Bypass line, there will only be a common RCD of 300 to
500 mA at the head of the installation for both lines.
• Output protection will be done with a circuit breaker of C characteristic or an equivalent one.
It is recommended to distribute the output power, into four lines as minimum. Each one of them will have a protection circuit breaker sized to the quarter of the nominal power.
This kind of outgoing distributions will allow that any fault in any device connected to the equipment, that makes a shortcircuit, will affect to the line with the faulty device only. An uninterruptible power supply will be guaranteed to the rest of connected loads, due to the protection tripping of the affected line by the short-circuit only.

• When replacing a fuse, do it for another of the same type, characteristics format and size.
• Under any concept the input power cord will be connected to the output of the equipment, either directly or through other ways.
• Models with separate bypass line, a galvanic isolation transformer has to be installed in any of the two lines that supply the UPS (rectifier input or static bypass), to avoid the direct union of the neutral of both lines through the internal wiring of the equipment.
This is applicable when the two lines are supplied from different mains, i.e.:
Two different electrical companies.
An electrical company and genset, ...
• All the equipments have an auxiliary terminal strip to install an external emergency power off button (EPO), and it will belong to the user property.
Type of circuit is selectable through the LCD panel of the equipment. The contact is preset from factory as normally open, so the button must be switched to close the circuit and the voltage to the loads is broken. To establish the power supply to the loads again, the EPO button must be deactivated.
•
EPO doesn't affect to the power supply of the equipment, it only breaks the power supply to the loads as a safety measure.
When supplying input voltage to a UPS with fitted in or separate static bypass, although the inverter is still turned «Off» (deactivated) it doesn't mean that at the output there will not be voltage.
So, to do it, the input and static bypass switches will have to be turned «Off».
Put warnings of danger and/or emergency switches if the safety
Standards require it in your particular installation.
• It is possible that the UPS supplies output voltage through the manual bypass to those equipments that incorporate it either standard or optional, so it will have to be considered as regards to safety. If it were necessary to break the output supply of the equipment in this situation, deactivate the outgoing distribution protection or in case of lack of it the general protection of the distribution panel that feeds the UPS.
• All power supply electrical cables have to be fixed to the equipments and loads, interfaces, etc..., to unmovable parts and in the way to avoid treads, trips on them or fortuitous pulls.
• It is essential the Neutral connection to the input in three phase equipments in the foreseen terminal for that purpose.
• CHASSIS or RACK mounted equipments are destined to be installed in a predetermined set to be done by professionals.
The installation has to be designed and executed by qualified personnel, who will be the responsible to apply the safety and EMC regulations and standards that controls the particular installations where the product is destined.

TWIN PRO series assure an optimal protection of any critical load, keeping the power supply voltage to the loads between the stated parameters, with no break, during a blackout, deterioration or perturbations of electrical commercial mains and with a wide range of available models (from 4 to 20kVA), it allows adapting the model to the end-user needs.
Thanks to the used technology, PWM (pulse width modulation) and double conversion, UPS from SLC TWIN PRO series are compact, cold, silent and high efficiency.
The double conversion principle cancels any perturbations from mains energy. A rectifier converts the AC alternating current from input mains into DC direct current, keeping an optimal battery charging level and supplying the inverter, and at the same time creates an AC sinewave voltage ready to feed the loads permanently. In case of UPS input mains fault, the batteries supplies clean energy to the inverter.
The UPS design and construction from SLC TWIN PRO series has been done in accordance with the international regulations.
These equipments allow the upgrading by means of the connection of additional modules of the same power rate, to get redundancy (i.e.: N+1) or to increase the capacity of the system.
So, this series has been designed to maximize the availability of the critical loads and to assure that your business is protected against perturbations of voltage, frequency, electrical noises, blackouts and mains faults, which are present in the energy distribution lines. This is the main target of the UPSs from SLC
TWIN PRO series.
This manual can be applied to the standardised and stated models in table 1.
3.3.1. Main features.
• True on-line double conversion and independent output frequency from mains.
• Output power factor of 0,9 and pure sinewave, suitable for almost any kind of loads.
• Input power factor > 0,99 and high general efficiency (> 0,92 for single phase input or > 0,93 for three phase). High energy saving and low cost for the user's installation (wiring) is achieved, as well as low input current distortion, so mains pollution is decreased.
• Great adaptability to the worst conditions of the input mains.

3.4. Options.
Depending on the selected configuration, the equipment can include any of the following options:
3.4.1. 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 attenuation of the electrical noises.
The isolation transformer can be installed at the input or output of the UPS from SLC TWIN PRO series and it will always be located out from the equipment enclosure.
3.4.2. 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.
The basic difference between this option and the manual bypass integrated in the own UPS enclosure consists in a better manoeuvring, because it allows a complete disconnection of the UPS from the installation.
3.4.3. 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 controlling and management at the manager system disposal. This facility is got through the SNMP adaptor, which is well-known by the main software and hardware manufacturers.
The available SNMP option for SLC TWIN PRO 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.
3.4.4. AS400 card.
See section 4.3.8.4.
3.4.5. Parallel cable.
It is the used parallel cable to make the parallel communication among all the equipments that makes a system.
All models from SLC TWIN PRO series already include the parallel kit as standard. In case, it is needed to upgrade the power of the equipment or to get redundancy by paralleling more equipments of the same power, this cable will be needed.
3.4.6. MODBUS protocol.
The big IT systems based on LANs and WANs, many times they require 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 PRO series is also ready to be integrated in this type of environments through the external
“Winpower CMC card” device with MODBUS protocol.

USER MANUAL
4. Installation.
• Check the Safety instructions, from section 1.2.3.
• 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.
• This UPS has to be installed by qualified staff and it can be used by personnel with no specific training, just with the help of this «Manual» only.
• 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 generator, so the user has to take the needed cautions against direct and indirect contacts.
• When there is only one equipment, omit all the instructions and their implicit connections as regards to parallel systems.
• Parallel system installation needs a switchgear panel with input, output and static bypass single protections (the last one for TWIN/3 PRO models higher than 10 kVA only), and a manual bypass too.
•
•
This switchgear panel allows isolating only one equipment from the system, when facing any malfunctioning and supplying the loads with the rest of equipments during the preventive maintenance or during the reparation of itself.
Under request a manual bypass panel can be supplied for a single equipment or a particular system.
In parallel systems, the length and cross section of the cables that go from the switchgear panel till one of the
UPSs and vice versa, will be the same for all of them without any exception.
Battery circuit is not isolated from input voltage. Hazardous voltages can be found out between the battery terminals and earth. Check that there is not input voltage before doing any intervention on them.
4.1. To be considered in the installation.
• All the equipments and battery sets have terminals as connection parts for power and connectors for communications.
• Terminals for separate bypass line are only available in TWIN/3
PRO models higher than 10 kVA.
• 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.
For the bypass current stated in the nameplate, has to be considered two groups of equipments:
Equipments up to 10 kVA TWIN/3 PRO. Current on phase R is higher to the other two, because the input of the UPS is common with the bypass line.
Equipments > 10 kVA TWIN/3 PRO. These equipments have separate terminals for UPS input and bypass line.
• Protections of the switchgear panel, will have the following features:
For input and bypass lines, 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. Pay attention to the UPSs up to 10 kVA and three phase input, because a four pole switch has to be fitted in as input protection and a second one of two poles between this one and the own UPS, in order to protect the phase R and neutral.
• 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.
• If it is added peripherals to the input, output or bypass 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
•
Overload conditions are considered as nonpermanent and exceptional operating mode.
When an equipment incorporates a galvanic isolation transformer, as standard, as an option or either installed by yourself, either at the UPS input, bypass line, output or at all of them, protections against indirect contact has to be fitted in (residual current 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 transformer)
• Remind you that all external isolation transformers already installed 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 respective local and/or national low voltage regulations.
• All standard UPSs have batteries in the same enclosure of the equipment , less those ones as B0 and B1. In the first ones, the battery protection is by internal fuses and there is no access to the end-user.
•
Accumulator cabinet or modules have battery protection too, and in this case, they are duplicated. An internal ones through fuses with no access for the end-user and an additional ones by means of a two pole circuit breaker.
IMPORTANT FOR SAFETY: In case of installing the batteries by yourself, the accumulators have to be provided with a two pole circuit breaker protection sized to the features stated in table 2.
4.2. Reception of the equipment.
4.2.1. Unpacking and content checking.
• 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.

Regulations 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).
For equipment with three phase input, which are connected to a power distribution system type IT, the protection will be four poles in order to break the three phases and neutral in the same manoeuvring.
Overload conditions are considered as a nonpermanent an exceptional 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 characteristic or any other equivalent one.
• To make the power, control connections or insert the option cards, etc..., it is needed to remove the screws that fix each cover and the own covers.
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, output and bypass).
• Check the correct torque in the screws of the power blocks.
• In installations with only one UPS, the "Jumper" (cable as bridge mode) connected from factory between the terminals JP1 and JP2 has to be kept as it is.
For equipments connected in a parallel system, this "Jumper" has to be removed.
Act according to the installation or otherwise the UPS or parallel system will not work.
4.3.1. Connection of input power block.
• As this is a device with class I protection against electric shocks, it is essential to install a protective earth conductor (connect earth( )). Connect the conductor to the terminal, before connecting the power supply to the input power block.
• In accordance with safety standard EN-IEC 62040-1, the installation has to be provided with a «Backfeed protection» system, as for example a contactor, which will prevent the appearance of voltage or dangerous energy at the input mains during a mains fault (see figure 10 and respect the circuit diagram of the particular «Backfeed protection» for the equipment with single phase input ( TWIN PRO) or three phase input ( TWIN/3 PRO up to 10 kVA)).

• In parallel systems, the length and cross section of the cables that go from the switchgear panel till one of the
UPSs and vice versa, will be the same for all of them without any exception.
• 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 circuit 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 assured due to the triggering of the protection, because the line affected by the short-circuit will trip its protection.

• As this is a device with class I protection against electric shocks, it is essential to install a protective earth conductor (connect earth ( )). Connect the conductor to the terminal or bar, before connecting the power supply to the
UPS input.
• Make sure that all the loads connected to the UPS are only connected 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 together, to the main protective earthing terminal ( ) and to the frame of the device.
4.3.6. 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 open contact. 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 functionality, normally closed.
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 open EPO type, with the inconvenience of the sudden break in the power supply to the loads, but with a complete 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.

4.3.7. Connection in parallel.
4.3.7.1. Introduction to the redundancy.
N+X is usually the most reliable power structure. N means the minimum quantity of equipments that the total load needs; X means the quantity of redundant equipments, so it means, the quantity of faulty UPSs that the system can allow at the same time. As higher is X, the highest will be the reliability of the system. For those cases where the reliability is the most important point, N+X will be the optimal mode.
Up to 4 equipments can be connected in parallel to set a share and redundant output in power.
4.3.7.2. Installation and parallel operating.
• 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).
• Parallel connection bus. Use the bundle with 25 signal cables with mesh and DB25 connectors in the ends to joint up to 4 equipments as maximum. Each bundle has a male and female connector in the ends, which have to be connected in the correlative equipments. It is essential to close the loop of the parallel bus.
•
The length of the parallel cable has 3 metres and it can't be extended under any other concept due to the risk of interferences and communication failures that it could cause.
In those installations with only one UPS, the “Jumper”
(cable as bridge mode) connected from factory between the terminals JP1 and JP2 has to be kept in this place.
For equipments connected in a parallel system, this “Jumper” has to be removed.
Proceed according to your installation or otherwise the UPS or parallel system will not work.
• The installation of the parallel systems, has to be provided by a switchgear panel with individual protections for input, output, static bypass (this last one for TWIN/3 PRO > 10 kVA models only), also a manual bypass with mechanical lock, see figures 12 and 13.
This switchgear panel allows isolating only one equipment from the system, against any failure and feed the loads with the rest of equipments during the preventive maintenance or its fixing. In the same way, it allows removing an equipment in parallel and replace it or put it in parallel again once it is fixed, but without breaking the power supply to the loads.
Under request a manual Bypass panel can be supplied for a single equipment or particular system.
• Regarding the protection panel, it is better to size it for future foreseen upgrading. This way, both the installation of any new
UPS in the parallel system is easier, and the risks due to electrical discharge are minimized because the low voltage panel is manoeuvred for those cases that it is not possible to shutdown the loads.
• Respect the connection procedure for input and bypass
( TWIN/3 PRO > 10 kVA) described in the previous sections of this chapter.
• Respect the established procedure to make the connection of the battery modules for those equipments with extended back up time, which has been described in the previous sections of this chapter.
• Respect the established procedure to make the connection of the output (loads), which has been described in the previous sections of this chapter.

• In parallel systems, the length and cross section of the cables that go from the switchgear panel till one of the
UPSs and vice versa, will be the same for all of them without any exception.
In the worst case, the following deviations have to be strictly respected:
When the distance among the UPSs and the protection panel is lower than 20 metres, the difference in the length between the input and output cables of the equipments has to be lower than 20%.
When the distance among the UPSs and the protection panel is higher than 20 metres, the difference in the length between the input and output cables of the equipments has to be lower than 10%.

4.3.8.4. AS400 interface (option).
• 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).
• UPS has a dry contact card for the AS400 communication protocol, it provides digital signals in a free potential way, with a maximum applicable voltage and current of 240 V ac or
30 V dc and 1A.
• This communication port makes possible the dialogue between the equipment and other machines or devices, through the 5 dry contacts supplied in the terminal strip included in the same card and to each one of them an alarm of the 8 available can be assigned (see table 5).
Also there are other three additional terminals with only one common, for an installation of an external On/Off switch to the equipment and a third one with free setting among EPO,
Shutdown or "On-Off" remote control.
From factory all contacts are normally opened, being able to set them separately one by one, by means of the Hyper
Terminal software or equivalent.
• The most common use of this type of ports is to provide the needed information for the closing file software.
• This card has a RS232 port through a RJ connector. So, in case of requiring a DB9 connector, use the adaptor RJ / DB9 supplied with the AS400 card.
• For more information, contact with our S.T.S. or our nearest distributor.
Installation.
• Remove the protection cover from the AS400 slot of the equipment.
• Take the AS400 card and insert it into the reserved slot.
Make sure that it is well connected, so the resistance that the own connector inside the slot makes has to be overcome.
• Make the needed connections in the alarm terminal strip.
• Put the new protection cover that it is supplied with the
AS400 card and fix it through the same screws that fixed the original cover.
4.3.9. 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.
• Installation procedure:
Go to website: http://support.salicru.com
Choose the operating platform that you need and follow the instructions described in the web site to download the software.
When downloading the needed files from Internet, enter the following licence to install the software:
511C1-01220-0100-478DF2A .
When the computer is rebooted, WinPower software will be shown as an icon with plug shape and green colour in the system tray, near the clock.
Fig. 15. Main screen of the monitoring software.
4.3.10. Considerations before starting up the connected loads.
• It is recommended to charge the batteries for 8 hours as minimum before using the UPS for first time.
For models with single phase input ( TWIN PRO) or three phase ( TWIN/3 PRO up to 10 kVA):
It will be necessary to supply power supply voltage to the equipment and turn "On" the circuit breaker switch on the back M1. The battery charger will be started up automatically.
For models with three phase input ( TWIN/3 PRO > 10
kVA):
Supply voltage to the input and bypass terminals of the equipment. Turn "On" the circuit breakers switches on the back M1 and M2 and check that the neutral switch N is in "On" position. Battery charger will work automatically.
For external battery modules:
Also for those models with batteries or extended back up time modules external to the equipment, the battery circuit breaker of each cabinet has to be turned "On".
• Although the equipment can work without charging the batteries during the stated 8 hours 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 peripherals in order to avoid that the equipment becomes blocked under the worst conditions.

5.6.1. Operating principle.
Integrated manual bypass in all UPS from SLC TWIN PRO is very useful, but a wrong use can cause irreversible consequences for both the UPS and connected loads at its output.
Therefore, it is important to respect the manoeuvring over the switch as it is stated in the following sections.
5.6.2. Transference to maintenance bypass.
• The procedure to transfer from normal mode to maintenance bypass is the same for a single equipment or a parallel system, less the quantity of actions:
For a single equipment.
– Press over the key of the UPS for more than 3 seconds to shutdown the inverter. The acoustic alarm will beep for 3 seconds. The equipment will transfer to
"Bypass mode".
For a parallel system.
– Press over the key in any UPS for more than 3 seconds to shutdown all the inverters. The acoustic alarm will beep for 3 seconds. The equipments that belong to the current parallel system will transfer to
"Bypass mode".
Put all the equipment/s on manual bypass. To do it remove the cover from manual bypass switch, which is located at the back of each equipment and turn all the switch to position "BYPASS".
In parallel systems, proceed in the same way in each equipment.
Keep in mind that on "Bypass mode" or with the switch on "BYPASS" position, the loads will be exposed to fluctuations of voltage, frequency and mains faults or blackouts, so in case it were possible, choose one day with the lowest probability of faults (days without fluctuations, days without storms,... ) and do it as fast as possible.
Turn the input and bypass circuit breaker protections
( TWIN/3 PRO > 10 kVA) of the equipment to "Off".
In parallel systems, proceed in the same way over the same protections and in each equipment.
The UPS still supplies output voltage, from mains directly
USER MANUAL
or through the static bypass line ( TWIN/3 PRO > 10 kVA only), through the manual bypass of the equipment.
Also, if the protection panel has manual bypass switch, remove the mechanical lock and turn the switch "On"
(BYPASS).
In this case and in this case only, turn the output
switch/es from distribution panel to "Off", depending if there is only one UPS or a system with "N" equipments in parallel.
The UPS is completely shutdown and inactive and loads are supplied through the manual bypass of the distribution panel.
5.6.3. Transference to normal mode.
• The procedure to transfer from maintenance bypass to normal mode, is the same for a single UPS or parallel system, less the quantity of actions to make:
If the protection panel has manual bypass switch:
– Turn the output protection/s of the distribution panel to
"On" previously, depending if there is a single UPS or a system with "N" equipments in parallel.
If the manual bypass switch is manipulated before turning "On" the output switch/es of the protection panel, the loads will not be fed.
– Turn the manual bypass switch of the panel to "Off"
(UPS) and put the mechanical lock.
To avoid wrong manoeuvring the mechanical lock has to be fit, otherwise the equipment and loads are exposed to serious damages, even the destruction of both or fire.
Turn input and bypass circuit breaker protections of the equipment ( TWIN/3 PRO > 10 kVA) to "On".
In parallel systems, proceed in the same way in all the equipments over the same protections.
Move the manual bypass switch to position "UPS" and put the protection cover the manual switch back.

Bypass without output voltage:
The UPS is running on bypass mode without output voltage.
– This function can be activated through the settings of the control panel (by means of password) or by means of a suitable software (WinPower, ...)
– The power of the UPS will be the 60% of the nominal, when it is running on "Frequency converter mode" in equipments with single phase input. Nevertheless for equipments with three phase input, there is not any derate.
Warning.
When there is a "Warning", it means that there is something wrong in the UPS operating. Usually, the problems are not serious and the equipment can be kept running.
However, pay attention to it, because the UPS could fail.
Fig. 22. Bypass without output voltage screen.
ECO mode:
Once the UPS is started up, the energy that feeds the load/s comes from the commercial mains directly through the internal filters, meanwhile the voltage is inside the limits set as normals.
When input power supply fails, due to fault or wrong, the equipment will transfer from "Line mode" to "Battery mode" to supply the load/s properly.
– This function can be activated through the control panel (by means of password) or through a suitable software (WinPower, ...)
– The transfer time between "ECO mode" and
"Battery mode" is around 10 ms. Nevertheless, this time can be excessive for some type of loads, so the ECO mode operating has to be considered according to this issue.
Fig. 25. Warning screen.
Fault.
When a fault occurs, it reveals that some serious problems have happened, the UPS will break the output voltage or will transfer to bypass and the alarm will be saved. The screen will change its blue colour to orange as an intuitive warning mode.
Fig. 23. ECO mode screen.
Frequency converter mode.
In the frequency converter mode, the static bypass is disabled and any of the operating modes of itself, because the input and output frequencies of the UPS are different
(50 or 60 Hz). When the input power supply fails, due to fault or wrong, the equipment will transfer to "Battery mode" to feed the load/s properly.
Fig. 26. Fault screen.
Overload.
When the UPS is overloaded, an alarm is triggered with a beeping of twice per second. Decrease the load level connected at the output of the equipment, till the power doesn't exceed from the nominal power of itself.

6.4. Special functions
The UPS has some special functions, that could satisfy a special application of the user.
In case you require any of these special functionalists, contact with the S.T.S. to change the standard configuration from factory.
6.4.1. Operating on ECO mode.
6.4.1.1. Short description of the ECO mode.
• "ECO mode" function allows supplying the load/s from mains directly, through the internal filters only, meanwhile the energy is inside the limits, so the UPS allows an "Economy mode" and with high efficiency > 0,97.
• When mains is out of tolerances (voltage and/or frequency), or there are mains failures or blackouts in the power supply, the UPS will transfer to "Normal mode" or "Battery mode" depending on the case and the load/s will be supplied in a safety way.
• Nevertheless, the contras are:
Load can't be protected at 100 %, because on "Line mode" the load/s are supplied from commercial mains directly and through the internal filters of the bypass.
The transfer time of the "ECO mode" to "Battery mode" is
10ms approximately.
Therefore, this function is not suitable for some sensitive loads or areas with unstable power supply.
6.4.1.2. To establish the ECO mode function.
• The function can be activated or deactivated through the
“Setting” submenu (see section 6.3.7).
6.5. Operating as frequency converter.
(*) Accessible with the S.T.S password only
Fig. 36. Identification submenu screens.
6.3.7. Setting submenu.
• This submenu is exclusively reserved for Service and Technical Support or authorised personnel and it is only accessible by password.
Some settings modify the specifications and settings to activate or deactivate some functions. Wrong modifications and/ or settings can make possible faults or lack of protection to the own UPS and even they can affect or damage the load/s or battery.
• Almost all the settings can only be done meanwhile the UPS is on bypass mode.
6.5.1.1. Short description of the frequency converter function.
• In the converter mode, the static bypass is disabled and any of the operating modes of itself, because the input and output frequencies are different (50 or 60 Hz). When input mains fails, either due to a blackout or wrong, the equipment will transfer to “Battery mode” to supply the load/s properly.
• The output frequency is set to the preset value and required by the loads. Nevertheless, the contra is the capacity of the
UPS, which is derated up to the 60% of the nominal in the
"Converter mode”.
6.5.1.2. To establish the Converter mode function.
• The function can be activated or deactivated through the
“Setting” submenu (see section 6.3.7).

USER MANUAL
7. Maintenance, warranty and service.
7.1. Battery maintenance.
• Pay attention to the safety instructions regarding battery and the stated in section 1.2.3.3.
• The UPSs from SLC TWIN PRO series only requires a minimum maintenance. The used battery in the standard models is lead acid, sealed, VRLA and maintenance free.
These models require a minimum of reparations. The only requirement is to charge the UPS regularly, in order to prolong the battery lifetime. Meanwhile, it is connected to the power supply, never mind if the UPS is ON or OFF, it will keep the batteries charged and will give protection against overcharging and undercharging.
• The UPS has to be charged once, every 4 or 6 months if it has not been used for long time.
• In hot areas, battery has to be charged every 2 months. The charging time has to be 12 hours as minimum.
• Under normal conditions, the battery lifetime is from 3 to 5 years 25º C. In case that the battery was not in good conditions, it has to be replaced before. This replacement has to be done by qualified staff.
• Always replace them with the same quantity and type.
• Do not replace one battery only. All batteries have to be replaced at the same time and following the instructions of the manufacturer.
• Usually, the batteries should be charged and discharged every 4 or 6 months. The charging would be started after shutdown the UPS due to a low battery (discharging). Charging time for standard UPS should be 12 hours as minimum.
7.1.1. Notes for installing and replacing the batteries.
• If it is needed to replace the connection of any wire, purchase original parts through authorised distributors or service centres in order to avoid overheating and sparks with fire risk because the size is not enough.
• Do not short the + and - poles of the batteries, there is risk of fire or electrocution.
• Be sure that there is no voltage before touching the batteries.
Battery circuit is not isolated from the input. Hazardous voltages can be found between the battery and earth terminals.
• Although the input and bypass circuit breaker switches (in
TWIN/3 PRO > 10 kVA models) are turned off, the internal parts of the UPS are still connected to the batteries, so there are hazardous voltages inside.
Therefore, before doing any reparation or maintenance task, the internal battery fuses have to be removed and/or the interlink connections between them and the UPS.
• Batteries have hazardous voltages. The battery maintenance and replacement have to be done by qualified personnel and familiarised with them. Nobody else can manipulate them.
7.2. UPS Trouble Shooting guide.
If the UPS doesn't work properly, check the information given by the LCD of the control panel, according to the models and power of the equipment. Try to solve the problem by means of the established steps in the tables 9 to 11. In case the problem persists, consult with our Service and Technical Support S.T.S..
When it is needed to contact with our Service and Technical Support S.T.S. , provide the following information:
• UPS model and serial number.
• Date when the problem occurred.
• Complete description of the problem, including the information given by the led or LCD panel and the status of the alarms.
• Power supply condition, type of load and the level connected to the UPS, ambient temperature, cooling conditions.
• Information of the batteries (capacity and battery quantity), if the equipment is (B0) or (B1) -with external batteries-.
• Other informations that you may think that they are important.

8.2. Glossary.
• AC.- It is nominated as alternating current (abbreviation
• Bypass.- Manual or automatic, it is the physical junction be-
• DC.- The direct current (CC in Spanish, DC in English) is the continuous electron flow through a cable between two points with different potential. Unlike the alternating current, in direct current the electrical loads always flow in the same direction
• DSP.- It is the acronym of Digital Signal Processor. A DSP is a system based on a processor or microprocessor that has
40 in Spanish CA and in English AC) to the electrical current in which the magnitude and direction varies in a cyclic way. The most common wave shape of the alternating current is sinewave, because the energy transmission is better. Nevertheless, some applications could need other period wave shapes, like triangular or square tween the input and the output electric device.
from the highest potential point to the lowest one. Although, usually the direct current is identified with the constant current (for example the one supplied by the battery), it is continuous any current that always maintain the polarity.
instructions in it, a hardware and an optimised software to develop applications where numerical operations are needed with very fast speed. Due to this, it is very useful to process analogical signals in real time: in a system that runs in this way (real time) samples are received, usually coming from an analogical/digital converter(ADC).
• Power factor.- It is defined as power factor, p.f., of an alternating current circuit, as the ratio between the active power,
P, and the apparent power, S, or as the cosines of the angle that make the current and voltage vectors, designating as cos φ, being φ the value of that angle.
• GND.- The term ground, as its name states, refers to the potential of the earth surface.
• EMI filter.- Filter able to decrease the electromagnetic interferences, which is the perturbation that happens in a radio receptor or in any other electrical circuit caused by the electromagnetic radiation coming from an external source. Also it is known as EMI, ElectroMagnetic Interference, Radio Frequency Interference or RFI. This perturbation can derate or limit the efficiency of the circuit.
• IGBT.- The Insulated Gate Bipolar Transistor is a semiconductor device that is used as a controlled switch in power electronic circuits. This device has the feature of the gate signal of the effect field transistors with the capacity of high current and low voltage saturation of the bipolar transistor, combining an isolated FET gate for the input and a bipolar transistor as switch in a single device. The triggering circuit of the IGBT is as the
MOSFET one, while the driving features are like the BJT.
• Interface.- In electronic, telecommunications and hardware,
USER MANUAL
an interface (electronic) is the port (physical circuit) through which are sent or received signals from a system or subsystems toward others.
• kVA.- The voltampere is the unit of the apparent power in electrical current. In direct current is almost equal to the real power but in alternating current can defer depending on the power factor.
• LCD.- LCD acronym of Liquid Crystal Display, device invented by Jack Janning, who was employee of NCR. It is an electric system of data presentation based on 2 transparent conductor layers and in the middle a special crystal liquid that have the capacity to orientate the light when trespassing.
• LED.- LED acronym of Light Emitting Diode, is a semiconductor device (diode) that emits light almost monochrome with a very narrow spectrum, it means, when it is direct polarized and it is crossed by an electric current. The colour, (wave longitude), depends on the semiconductor material used in its construction, being able to vary from the ultraviolet one, going through the visible spectrum light, to the infrared, receiving these last ones the denomination of IRED (Infra Red
Emitting Diode).
• Circuit breaker.- A circuit breaker or switch, is a device ready to break the electrical current of a circuit when it overcomes the maximum set values.
• On-Line mode.- Regarding to an equipment, it is on line when it is connected to the system, and it is in operation, and usually has its power supply turned on.
• Inverter.- An inverter, is a circuit used to convert direct current into alternating current. The function of an inverter is to change an input voltage of direct current into a symmetrical output voltage of alternating current, with the required magnitude and frequency by the user or the designer.
• Rectifier.- In electronic, a rectifier is the element or circuit that allows to convert the alternating current into direct current. This is done by rectifier diodes, which can be solid state semiconductors, vacuum or gassy valves as the mercury vapour. Depending on the features of the alternating current power supply used, it is classified as single phase, when they are fed by a single phase electrical mains, or three phase when they are fed by the three phases. Depending on the rectification type, they can be half wave, when only one of the current semi-cycles is used, or full wave, where both semicycles are used.
• Relay.- The relay(in French relais, relief) is an electromechanical device that works as a switch controlled by an electric circuit where, through an electromagnet, a set of contacts are moved and it allows to open or to close other independent electric circuits.
• SCR.- Abbreviation of «Silicon Controlled Rectifier», called commonly as Thyristor: semiconductor device of 4 layer that works as almost an ideal switch.
• THD.- They are the acronyms of «Total Harmonic Distortion». The total harmonic distortion is done when the output signal of a system is not equivalent to the one that enter into it. This lack of linearity affects to the wave shape, because the equipment has introduced harmonics that they were not in the input signal. As they are harmonics, it means multiple of the input signal, this distortion is not so dissonant and it is more difficult to detect.
