Any packaging material must be recycled in accordance with the legal norms applicable to each country where the equipment is installed. Alternating current a.c.. Risk of UPS backfeed voltage. 2 • installation task. • Do not store, install or expose the equipment in corrosive, wets, warms, dusty or with conductive parts environments and never outdoors. Installation location will be cooled, dry and far from heat sources and with easy access. If possible in an environment with temperature control. • Avoid to locate, install or store the equipment in places with direct sunlight or high temperatures. Batteries can be damaged and/or make shorter its useful lifetime. In the exceptional and long exposition case to intense heat, batteries can cause filtrations, overheating or explosions, which can cause fires, burn or other injuries. High temperatures can also make deformation in the plastic enclosure. • Do not obstruct the cooling grids by entering objects through themselves or other orifices. • Locate the equipment as close as to the power supply outlet and loads to supply, leaving an easy access if it were needed an urgent disconnection. • All models with casters have four leveller parts -feet-, which are located at each corner of the base, with the purpose of locking and level the unit. Loosen them with the hand until they stop with the ground. With the help of a spanner, act on each one and loosen them half round more against the ground. In grounds slightly uneven, level the equipment by means of these leveller parts. Check that the equipment is completely immobilized. Fortuitous pulls of the connection cables of the equipment will indirectly be avoided, because unexpected movements will not happen. • Even though the interventions inside of the equipment, battery cabinet and battery manipulation is a task reserved to personnel with specific or qualified knowledge only and in par- ticular to (S.S.T.), it is mandatory to immobilize the equipment by means of the levellers parts -feet- stated in the previous point, before doing any action. Attention! Risk of tipping when removing the battery trays without stabilising the unit first. Do not remove more than one tray together, high risk of injury over the operators due to shock of the possible equipment fall down and/or entrapment. • Leave a minimum free space to cool the unit of: 25 cm at both sides. 50 cm at the rear side. 100 cm at the top side. and 150 cm at the front side. • It is recommended to leave an additional 75cm at both sides, for possible interventions of the (S.T.S.) or the needed clearance of the connection cables to facilitate the forward movement of the equipment. • Do not cut, deteriorate or manipulate the electrical cables, neither put heavy objects over them. Any of these actions could cause a short-circuit and make a fire or electrical discharge. Check that the electrical cables of connection, plugs and outlets are in good conditions. To manipulate over the connection terminals of the equipment, which has been already connected to mains, wait for five minutes after its complete isolation, before taking any action in it. 2.2.1. To keep in mind. • The UPS is supplied packaged from factory in the best way for its transport and shipment till its new owner or receiver. It is recommended to transport it packaged as close as possible to its final location. • When serious damages are observed in the packaging, and due to its level of deterioration damages can be sensed in the contents and/or the shock indicator is in RED, proceed according to the instructions stated in the own label of transport control. Keep the affected equipment isolated from other received equipments, waiting the pending inspection by qualified staff. In case it were needed to return it back to the factory or your distributor and it were not possible to use the same packaging due to the poor conditions of itself, contact with the appropriate person in order to agree the way and conditions for its return. • Respect the unpacking instructions, as well as the established mode to remove the equipment from the pallet. These operations require the work of at least two persons. • The equipment has to be in vertical position always. When moving the equipment, consider the slope of the ground or surface and the risk of tipping. • Be careful to not lift heavy loads without help, according to the following recommendations: , < 18 kg. , 18 - 32 kg. , 32 - 55 kg. , > 55 kg. • In case of an accidental equipment dropping or if the enclosure is damaged, do not start it up under any concept. This kind of fault can cause fire or electrical discharge. Contact with our (S.T.S.). • Some models include casters to move it till its location. They are not designed for long distances or constant movements. The equipments shall be guided by two persons as minimum, which will be placed on either side and oriented to the walking direction. • UPSs are electronic equipments. Avoid jolting or bouncing like those produced by moving the equipment over an uneven or wavy surface. • When moving an equipment from a cold place to a warm environment and vice versa, it can cause condensation (small water drops) in the external and internal surfaces. Before installing a moved equipment from another place or even packaged, the equipment will be left for a minimum time of two hours in the new location before making any action, with the purpose of adapting it to the new environmental conditions and avoid the possible condensations. The UPS has to be completely dry before starting any 3 • All power supply electrical cables have to be fixed to the equipments and loads, interfaces, etc..., to immovable parts and in the way to avoid step on it or go through them with an transport medium or expose them to fortuitous pulls. • Be careful to not wet it, because it is not waterproofed. Do not allow entering any kind of liquids in, otherwise shutdown it immediately and contact with the (S.T.S.). • If the enclosure of the equipment is in contact with liquids or high density saline air accidentally, dry it with a soft and absorbent cloth quickly. Check that no liquid has entered inside the unit and act accordingly. • To clean the equipment, wipe over a damp cloth and then dry it. Avoid liquids sprinkling or spillage that could enter through the slots or cooling grids, which may cause fire or electric shock. Do not clean the equipments with products that could have alcohol, benzene, solvent or other inflammable substances, and even if they are abrasive, corrosive, liquids or detergent. • Never manipulate the equipment with wet hands. • If it is observed that the UPS exhausts smoke or toxic gas, shutdown it immediately and disconnect it from power supply. This kind of fault can cause fire or electrical discharge. Contact with our (S.T.S.). • Do not put either materials or parts over the equipment that obstruct the correct visualization of the synoptic. • Consult the documentation before doing any action. A wrong manipulation over the switches can cause important production losses and/or failures in the equipments. • 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 the same as the power supply cables, but with green colour with or without the yellow strip. • The protection earth must be connected to the frame or metallic chassis of any electrical equipment, by means of the foreseen terminal (in our case to the UPS, battery cabinet when it is available and loads), assuring that it is done before turning on the input voltage. It is essential that cables that feed the loads have their respective protection earth cable. When branch circuits are made, i.e. by means of terminal strips, it is essential to have a protection earth terminal in each one of them. • 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, the input power supply cable can’t be disconnected, because the general protection earth cable of the own UPS and all loads connected at the output will be disconnected too. Due to the same reason, the general protection earth cable of the building or switchgear panel that supplies the UPS will not be disconnected. • Cross cable sections used to supply the equipment and loads to be fed, 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. • UPS equipments can be manufactured in four different configurations of Input-Output: Three phase - Three phase. Three phase - Single phase. Single phase - Three phase. Single phase - Single phase. For the correct operation of the UPS, it is needed the input Neutral cable or in case of its missing, it has to be created by means of an isolation transformer located between the power supply and the equipment. • The UPS doesn’t modify the input neutral regime at its output. Do not earth the output neutral. When, it is needed to modify the output neutral regime, an isolation transformer has to be located between the loads and the equipment. Before using the UPS for first time or after a long period of time (6 months maximum), it has to be connected to the power supply to charge the batteries for a minimum period of time of 12 hours. Although the equipment can operate with batteries discharged, it has to be kept in mind the possible risk of mains fault during the first operating hours, so the available back up time in the UPS batteries, can be lower than the expected. 2.2.2. General safety warnings. • All electrical connections and disconnections of cables from the equipment, including the control ones, will be done with no power supply and switches on rest position «O» or «Off». • Pay special attention to the labelling of the equipment that warns about the «Electrical shock hazard», inside the equipment there are dangerous voltages. Do not open, dismantle or modify the equipment, if this action is not stated in this document. To manipulate inside the equipment for repairing is restricted to qualified staff only. In case of maintenance or fault, consult to the closest (S.T.S.). A part from the implicit risk of electrical shock, any action that make the modification, internal or external of the equipment or just only the simple intervention inside of itself, which is not stated in this document, it can expire the warranty. • During the erection and commissioning operations is needed to open the front door and some models is required to remove the protection cover from terminals too. Once the respective actions are finalised, leave the equipment as it was, with the protection cover put back and front door closed. • To shutdown the equipment completely, follow the instructions in the start up and shutdown chapter. • In those models with separate bypass line, an isolation transformer has to be located in any of both input lines (rectifier input or static bypass), in order to avoid the direct connection of the neutral of both lines through the internal wiring of the equipment. This is only applicable when the two power supplies come from different lines, i.e.:: Two different electrical companies. One electrical company and a generator, ... • La The installation will have input protections sized to the currents of the equipment and stated in the nameplate label 4 • • • • • (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 non-permanent and 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, i.e. laser printers. Installations with redundant equipments or separate bypass line, there will be one and common RCD device only of 300 to 500mA for both lines at the beginning of the installation. 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 short-circuit, will affect to the line with the failure only. Power supply will be guaranteed to the rest of connected loads, because of the tripping of the affected line by the short-circuit only. Under any concept the input power cables will be connected to the output of the equipment, either directly or through other outlets. • • • • • When supplying input voltage to a UPS with static bypass or separate bypass line, the fact of having the inverter «Off» (shutdown), it doesn’t mean to not have voltage at the output terminals. To not have it, input and static bypass switches have to be turned «Off». Put warnings labels and/or emergency switches in the particular installation if the safety norms require it. • • 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, turn off the outgoing distribution protection or in lack of it, turn off the general protection of the distribution panel that feeds the UPS. • All the equipments have two auxiliary terminals to install an external emergency power off button (EPO), which will belong to the end-user. EPO doesn’t affect to the power supply of the equipment, it only breaks the power supply to the loads as a safety measure. • RACK mounted equipments are destined to be installed in a predetermined set to be done by professionals. Its 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. • 2.2.3. Safety warnings regarding batteries. • The manipulation and connection of the batteries shall be done and supervised by personnel with battery knowledge only. 5 Battery circuit is not isolated from input voltage, it is dangerous to touch any part of the batteries. Dangerous voltages can be found between the terminals of the battery set and the earth. Check that there is not any voltage at the input before taking any action over them. Before doing any action inside the UPS, disconnect the batteries. Check that no voltage is present and there is not potential danger in the DC BUS (capacitors) or in the endpoint of the battery set terminals. In equipments with separate battery cabinet, check that they are compatible before connecting them. When faulty batteries are replaced, the complete battery set has to be replaced, less exceptional cases in new equipments, were due to manufacturing faults it will only be replaced the defective ones. The replacement will be done by another one of the same type, voltage, capacity and quantity. All of them has to be of the same brand. Otherwise there is risk of explosion. Do not reuse faulty batteries. There could be an explosion or burst any battery with the involved problems and issues that could happen. Generally supplied batteries are installed in the same cabinet, case or rack of the equipment. Depending on the power, autonomy or both, they can be supplied separately from the equipment in another cabinet, case or rack, with the interlink cables among them. Do not modify its length. In those equipments requested without batteries, their acquisition, installation and connection of themselves will be done by the end-user and under his responsibility. Data concerning the batteries as regards to quantity, capacity and voltage, are stated in the battery label sticked beside the nameplate of the equipment. Respect these data, battery connection polarity and the supplied circuit diagram strictly. For an optimum and efficient operating, the battery set has to be located as close as possible to the equipment. Battery voltage can involve the risk of electric shock and can produce high short circuit currents. Observe the following preventive measures before manipulating any terminal block identified in the labelling as «Batteries»: Use the suitable IPE (Individual Protection Equipment): gloves and insulated shoes, protection glasses, suitable work clothes, ... Take off rings, bracelets or other metal hanging objects. Use tools with insulated handles. Disconnect the corresponding protection elements. When connecting a battery cabinet to the UPS, respect the cable’s polarity and color (red-positive; black-negative) indicated in the manual and labelling. Do not place metal tools or objects over the batteries. Risk of short-circuit and possible deflagration due to the accumulated hydrogen. Metallic particles of different sizes can be thrown due to the violent explosion of the short-circuit and/or the tool itself or the metallic object, which origin the incident, with the risk of significant damage to nearby people and other devices, instruments or machines. Never manipulate them with your hands or through conducting objects, do not short either the battery terminal block of the equipment or the own ones from the batteries. • In case the automatic software to shutdown the devices due to end of back up time is not installed, it is recommended to shutdown the loads and the UPS before depleting the autonomy of the batteries, as a preventive safety measure for the own loads. • If the equipment is not in operating during the night, weekends and holidays periods, it is recommended to shutdown the equipment completely. In particular during this last period and due to safety reasons, as it is an energy generator, and to safeguard batteries against unnecessary discharges during these periods of time. • When the equipment and/or battery module has a protection by fuse and it were needed to replace it, do it by another one of the same type, format and size. • After prolonged periods of time of disconnection, it is needed to recharge the batteries for 12 hours as minimum every 6 months, in order to avoid the irreversible degradation of them. • Never short the battery terminals due to the high risk that involves. It involves the detriment of the equipment and batteries. • Avoid mechanical efforts and impacts. • Do not open or mutilate the battery. Spilled electrolyte is harmful and toxic for the skin and eyes. • Do not dispose the batteries in a fire or expose it to high temperatures. Batteries may explode. • In case of contact of the acid with parts of the body, wash immediately with plenty water and call urgently to the nearest medical service. • Batteries involve a serious risk for health and environment. Their disposal should be done in accordance with the existing regulations. 6 3. STANDARD AND QUALITY GUARANTEE. 3.1. DECLARATION OF THE MANAGEMENT. 3.3.

Declaration of conformity CE of the product is at the client disposal under previous request to our headquarters offices. 7 In the description of this manual, there are references to «LV» (Low voltage) and «HV» (High voltage) abbreviations, described in the nomenclature of the model with an «A» for «LV» and omitted for «HV», grouping the following interval of voltages: • LV.- 3x200 to 3x230 V (115 to 133 V in single phase). • HV.- 3x380 to 3x415 V (220 to 240 V in single phase). 4. PRESENTATION. 4.1. VIEWS. These abbreviations do not have any other purpose than matching and/or helping in order to give a better comprehension of the detailed information in this document and even they are not shown either in the nomenclature, or in the reference of the nameplate model. 4.1.1.Views of the equipment. Figures from 1 to 20 show the illustrations of the equipments according to model, nominal operating voltage and input-output setting, which is summarised in the chart 1. Format of protections and size of the terminals shown in the figures of this document, always correspond to the highest power rate model manufactured in that cabinet, at the same power supply voltage and input-output setting. Nevertheless and as the product is in constant evolution, some discrepancies or small contradictions can arise. So, if any questions, the labels over the own equipment will prevail. All models can operate as single units or connected in parallel with other equipments of the same family, because the needed electronic kit is already included. Parallel connection can be done at any time when the upgrading requirements are needed to increase the supplied power of the equipment or in order to have redundant operating systems for installations with higher safety. Do not connect UPS equipments of different features versions, settings, back up times or duplicated addresses (i.e.: two equipments, although they are identical, coming from two parallel systems and with the same address) in parallel. In any parallel system only one and different address is assigned to each equipment that makes the system. Each equipment model corresponds to one power rate, voltage, frequency and input and output currents. All values of these features can be checked in the nameplate, located at the back of the front door (PF), and act in your installation accordingly. Model.

To describe the operating principle, it is taken as a reference and example the single line diagram of Fig. 25 and 26, corresponding to UPS with three-phase input and output setting, one with basic structure and the other one with separate bypass line. All the equipments works and operates in the same way, although they have common line or separate static bypass. 4.3. This UPS series has a battery set that stores energy during the normal operating mode (present mains) and they are discharged during the emergency operation (mains fault), keeping the critical loads running during the required time. Batteries are sized to supply full power to the assigned critical loads during the back up time for any load condition. Standard batteries are sealed Lead Acid, maintenance free and VRLA technology. Each cell or cell group (battery block) are duly marked in a permanent way, with polarity indication, voltage and safety warning required by the standard. Cells are duly assembled and electrically connected. Battery set is protected by means of a fuse holder with ultra fast fuses, ready for the described conditions in section «4.3.2. Rectifier-PFC stage». In normal operation (mains present and charged batteries), the battery set is working on floating voltage. As an option the battery set of Pb-Ca or Ni-Cd can be assembled in a cabinet or rack separately from the equipment, shared for systems made of two UPSs in parallel. UPS FUNCTION STAGES. This UPS series is structured in the following stages: • • • • • • • • • Batteries. I/O EMI filters. Rectifier-PFC (AC/DC). Batteries. Inverter (DC/AC). Static Bypass. Maintenance or manual Bypass. EPO emergency shutdown. Control panel. Control and communication Software. 4.3.4. Inverter stage (DC/AC). 4.3.1. I/O EMI filters. Constructive parts: • DC Bus: it is used to filter the DC and it is in charge of interconnecting the PFC and Inverter through the protection fuses. • IGBT three phase inverter bridge: it is equal to the PFC stage but in counter way, it is in charge of making the DC/AC conversion with the lowest distortion and highest efficiency. It is also using the Trench-gate technology of 4th generation. • Current sensor: as it has been described before, in this case conventional AC currents sensors are also used (current transformers ) for measurement and control the output current of the inverter to get a total harmonic distortion at the output voltage lower than 1% in full load conditions. • Output chokes: it is used an identical solution as the used at the input. These chokes are used by the inverter as energy storage elements (in switching times), for DC/AC conversion. EMI filter is a three phase low-band filter, which its function is to attenuate and cancel all the radio frequency perturbations. The filter performs in a bidirectional way: • It cancels the perturbations that comes from the line and protect the UPS control circuits. • It avoids the possible radio electrical perturbations that the UPS could generates flows through the line and affect to other equipments connected to it. 4.3.2. Rectifier-PFC stage (AC/DC). Constructive parts: • Input protection and switch: it is the particular protection of the PFC rectifier. • Current sensor: it uses alternating current transformers to measure and control the input current, to get a THDi < 3% at full load condition and even < 1% depending on the quality of mains. • “T” filter: it is used to attenuate the current ripple caused by the PFC switching. • IGBT's three phase bridge: it will be used to make the AC/ DC conversion with the lowest distortion and highest efficiency. To do that, it is used the Trench-gate IGBT technology of 4th generation. • Input chokes: They are used by the PFC rectifier as energy storage elements (in switching times), for the AC/DC conversion. • DC Bus: it is used to filter the DC needed for the correct operation of PFC converter and inverter. 22 Maintenance line (manual Bypass).

UPS-B single line diagram with operating flows. The control algorithm of the triggering signals of the thyristors assures a nil transfer time, and avoids short-circuits between the thyristors of bypass and inverter (shifting with zero cross current). 4.3.5. Static bypass stage. When the inverter can't keep the voltage to the critical loads due to overloads, short-circuits, current limits or faults, the UPS has a bypass circuit, which supplies isolation for the inverter and supplies the critical loads directly from electrical mains. The UPS controls the availability inverter-bypass permanently in order to make the shifting between them. The bypass stage is based on six double thyristors in semipack format, working as AC switches, three of them are for shifting the input over the output and the other three are for shifting the inverter over the output. The managing system of the SCR switches is based on drivers designed with a shifting system that responds to the following requirements: 4.3.6. Maintenance or manual Bypass. . All UPSs from this series are foreseen with an auxiliary line protected by a circuit breaker switch, which makes an electrical bridge between the input and output terminals. Managing this switch, properly together with the input and output, allows isolating electrically all the UPS elements from the electrical lines. The type of manoeuvring of the maintenance bypass is “make before break”, with the purpose of keeping the critical loads fed, even during the maintenance tasks. Full static shifting system. Shifting with no high transient currents. Shifting with no transfer time. 23 • Output three phase rectifier controller: independent per phase, it is easy adapted to different settings, either single phase or three phase. It is highlighted the use of the AFC control technique that allows getting an output voltage with a THDv lower than 1,5% with non-linear load at the output and good dynamic response against unexpected step loads. • Switching algorithm of the bypass thyristors. • Parallel control: high speed communication and inverter parallel connection. 4.3.7. Terminals for EPO. The UPS has two terminals to install an external button of emergency output shutdown (EPO). 4.3.8. Control panel. This UPS has a sophisticated control panel based on a DSP (Digital Signal Processor) that performs as interface between the UPS and end-user. Each UPS is equipped with an alphanumerical LCD panel, which automatically informs about the current status of the equipment and electrical measurements to the end-user. It is based on a tree menu, allowing an easy browsing through its screens. 4.3.9.2. Managing software of the equipment. Managing and control of different parts. Visualization software for user interface. Software of communication and protocol implementation. Managing software of parallel system. 4.3.9. Control software and communications. 4.3.9.3. Communications. AFC Control (Adaptive Feedforward Cancellation). It consists in the use of digital resonators connected in parallel and set to those frequencies where the consigns or perturbations to refuse are expected. This control technique allows doing the follow of the sinewave signals of reference of the output voltage in the inverter and input cur- rent of the active rectifier. It is important to highlight that the different controls of the UPS do not operate either isolated or locally, but they interact between them in such way that it results a global controller of coupled type. It means operating advantages like to adapt the rectifier to the load conditions immediately. The digital control software works at two different levels: • COM port to relays: It supplies a digital signals in a dry contact way, which makes possible the dialogue between the equipment and other machines or devices. By default the equipment is supplied with 4 signal relays with a preset programming (see chart 2), which can be modified at factory or by teh S.T.S. under request. Chart 6 shows all the alarms that can be set to any relay. A fifth relay can be supplied as an option and under request, which can be defined in the purchase order. Also there is a “shutdown” input that allows shutdown the inverter. The most common use of this type of port is to supply the needed information to the closing file software. • COM port RS-232 and RS-485: By means of the same DB9 connector supplies the RS-232 and RS-485 communication ports. They are mutually exclusive between them and they are used to connect the UPS with any machine or device that has this standard bus. The RS-232 port consists in the serial transmission of data, in such way that it can send a lot of information through a communication cable of 3 wires. The RS-485, unlike other serial communication channels, it uses 2 wires only to dialogue among the systems connected to this network. The communication is established by sending and receiving signals in differential mode, so it gives to the system high immunity to the noise and long range (approx. 800m). The used protocol is “MASTER/SLAVE” type. The computer or IT system (“MASTER”) asks for a determined data, and the UPS answers immediately (“SLAVE”). 4.3.9.1. Control software at low level. • Input three phase rectifier controller: PFC control and battery charge loops. The structure adopted of independent control per phase of cascade type allows managing both single phase and three phase inputs. The AFC control technique has been also applied, to assure a sinewave mains currents, with a THDi < 2%, and in phase shifting with the voltages, to balance the active power of all the system, to accelerate its response and make it insensitive against the load transients. In normal conditions, the rectifier is running and charging the batteries, controlling at any moment the charging current and floating voltage according to the temperature of themselves. The system is also in charge of minimising the charging current ripple that flows through them. When the input voltage or frequency is out of the correct operating range, it is shutdown and batteries are responsible of keeping the inverter in operation, which at the same time supplies the loads connected at the output of the equipment till the battery voltage decreases till the end of back up time. Another important feature of the rectifier is its bidirectional capacity of operation. This allows consigning a battery discharging current even with mains present. This quality performance will make possible to do a battery test both in full load and no load conditions. 4.4. OPERATING PRINCIPLE OF AN EQUIPMENT. This UPS series is a double conversion system AC/DC, DC/AC with sinewave output that supplies a safe protection in extreme conditions of electrical power supply (fluctuations of voltage, frequency, electrical noises, blackouts and mains faults, 24 etc...). Whatever the type of load to protect is, these equipments are ready to assure the quality and uninterruptible electrical power supply. The use of the transformerless technology allows a significant reduction of weight and volume in the equipments, by improving a lot important coefficients like the power/footprint ratio. • Basically its operating is the following: The rectifier, an IGBT three phase rectifier, converts the AC voltage in DC by draining a sinewave current (THDi <2%), charging the batteries with constant current/ voltage. Batteries supply the energy required by the inverter in case of mains fault. The inverter is in charge of converting the DC bus voltage into AC providing an alternating sinewave output, stabilised in voltage and frequency, ready to supply the loads connected at the output. The basic structure of double conversion is complemented with two new functional stages, static bypass switch and manual bypass switch. The static bypass switch connects the output load with bypass line directly in special conditions like overload or over temperature and it is reconnected to inverter again, once the normal conditions are restored. UPS B version has two separate lines for the rectifier and bypass stages increasing in the safety of the installation, because it allows the use of a second line (generator set, other company, etc...). The manual bypass switch isolates the UPS from mains and loads connected at the output, so the maintenance tasks can be done inside the UPS without interrupting the supply to the loads. 4.4.3. Operating with non-active inverter (). The inverter is non-active due to alarm conditions like overloads, over temperatures, etc... In this case the rectifier is still charging the batteries in order to keep their optimal charge status. The inverter is also non-active if the start up has not been done through the keypad of the control. In both cases, the output voltage of the UPS comes from the emergency bypass line through the static bypass switch (Fig. 25 and 26), on condition that the EPO is inactive. 4.4.4. Manual bypass operating (). When it is required to make any maintenance service to the equipment, it can be disconnected from mains without breaking the power supply of the system and affecting it to the critical load. The UPS can only be intervened by technical or maintenance staff, by means of the manual bypass switch (respect the corresponding operative instructions later on stated). 4.4.5. Smart Eco-mode operating. For those applications with lower requirements, the smart and efficient function «Smart Eco-mode», meanwhile the power supply is available, allows the equipment feeding the loads directly from mains through the solid state static bypass («Off Line» mode). In case of mains fault, the system will automatically shift to normal operating mode («On Line») and will supply the loads through the inverter with the energy of the batteries. The «Smart Eco-mode» operating mode improve the efficiencies between 4 and 4.5 % highest than «On Line» normal mode, so it is close to 100 %. The «Smart Eco-mode» operating does not ensure a perfect stabilization in frequency, voltage or sinewave shape (distortion) as in «On Line» normal mode, because the figures of these parameters depend on the static bypass line and preset activation ranges completely. The detection of these parameters can take up to 3 ms, so it is recommended to assess the advisability of using this operating mode, depending on the level of protection required by the loads. This operating mode is disabled from factory and the end/user can activate it, in case it were needed, according to section 7.3.2. and Fig. 45. 4.4.1. Normal operating (). With mains present, the rectifier converts the AC input voltage into DC, by boosting the DC voltage to an optimal level to feed the inverter and battery charger. The inverter is in charge of converting the DC bus voltage into AC providing an alternating sinewave output, it stabilises the voltage and frequency, ready to supply the loads connected at the output (Fig. 25 and 26). 4.4.2. Mains fault operating (). 4.4.6. Frequency converter operating. In case of mains fault or blackout, the battery set supplies the needed energy to feed the inverter. The inverter still operates normally, without noticing the lack of mains and the back up time depends in the capacity of the battery set only (Fig. 25 and 26). When the battery voltage reaches the low voltage, the control blocks the output in order to protect the batteries from being deep discharged. When mains is restored and after the first seconds of analysis, the UPS goes back to operate as it is described in the previous section «4.4.1. Normal operating». . This UPS can be set from factory as frequency converters, whether they has batteries or not, being able to operate from 50 to 60 Hz or vice versa. The equipments set as frequency converters, the static bypass and manual bypass are not available. So, those functions, measurements, alarm messages, parameter settings, as well as manoeuvring of the related switches will not be operative and they will not be taken into account. 25 U-V-W R-S-T N N COM. connections Inp.

Therefore, the fact of having +M reserve equipments, increases the back up time of the set, because the battery set is higher. • Modularity: capacity can be added to a UPS parallel system by adding equipments of the same feature, without needing to replace the equipments already installed. I.e., if time later, an installation with a parallel system of 2 UPSs is detected that the capacity of this system is not enough, it can be opted for adding a third equipment to the system, without replacing the 2 original equipments. OPERATING STRUCTURE OF A PARALLEL SYSTEM. This Uninterruptible Power Supply Systems s e r i e s , are designed and thought for its «parallel» connection with a maximum of four units, on condition that they are the same model (setting, voltage, power, frequency, back-up time, ...), all of them without adding hardware. Fig. 27 and 28, as an example, show the circuit diagrams of a three-phase input/three-phase output parallel system, with and without separate static bypass line. Both circuit diagrams are only showing the input-output power connections and the parallel control BUS. A part from the possible setting, conceptually, the parallel systems are divided in two similar structures and at the same time very different depending on the application. Systems connected in parallel or active parallel, supply the loads equally among them. Less when there is only one UPS, the system will be able to be redundant or non-redundant depending on the needs and requirements of the application. The UPS parallel system management of UPS series is done by a MASTER-SLAVES protocol, where only one equipment (MASTER) takes the control of the rest ones (SLAVES). So, the control of the output voltage, bypass shifting, disconnections, mains synchronisation, ...; are managed by the MASTER equipment, and transmitted to the SLAVES equipments through the management bus of the parallel system. This MASTER or SLAVE condition is dynamic as it is described later and it will depend on several factors (initial status of the equipments, chronological order of commissioning or shutdown of the system through one equipment or other one, ...) • Simple parallel system (non-redundant): a non-redundant parallel system, is that one where all UPSs supply the required power by the loads. Total power of the system based on N equipments of nominal power rate Pn, is N x Pn. If the system is operating with a load close or equal to the maximum and one of them faults, the load will be shifted to bypass automatically with make before break technique, because it will not be able to support the consumption demand due to the overload that it will be caused in the rest of UPSs. • Redundant system: a redundant system is that one has one or more UPSs than the minimum required by the total power of the system (depending on the redundancy level), being the load fair shared among them. So, the fault of any of them will cause that the damaged UPS will be out of the system and the rest will continue supplying the load with all the guarantees. Once the damaged UPS is fixed, it can be connected to the system in order to recover the redundant condition. A system with his configuration increases the reliability and assures an AC power supply of quality for the most critical loads. The quantity of redundant equipments to be connected has to be studied according to the requirements of the application. Parallel connection, redundant or not, adds several advantages a part from the connection itself: • Higher punctual power and back up time: in a parallel system of N+M equipments, it is considered the nominal maximum load of N equipments and +M are the reserve ones, so: N, is the quantity of equipments in parallel, corresponding to the minimum quantity required by the total needed power. +M, is the additional quantity of equipments corresponding to the residual safety power (redundant equipments). Although, in practice it can drain the total power in that the N+M system can supply, the redundancy requirement or conception does not advice it and in compensation there is a surplus of dynamic power against load demands. I.e., a redundant parallel system with 3 UPS of 40 kVA and N+1 configuration, the nominal maximum load contemplates 80 kVA (2x40 kVA), although the system can accept load demands up to 120 kVA (3x40 kVA). 27 again till its commissioning in order to protect it against mechanical impacts, dust, dirt, etc. • The packaging of the equipment has a cardboard pallet or wooden type depending on the case, expanded polystyrene corners, bag and polyethylene strip, all of them are recyclable materials.

Equipment immobilized and levelled. • To have access to the battery shelves, cabinet side covers have to be removed and they have to be unblocked. Shelves can be extracted through both sides and each one has a stopper. • All UPSs and battery modules, which have casters, have 4 stabiliser elements (PB), arranged next to each caster. • The purpose of the stabilisers elements (PB) is lay, immobilize and level the metallic cabinet once it has been located, in order to avoid possible overturns, in particular those ones that battery shelves can be extracted. Warning! Turnover danger when extracting the battery shelves without stabilising the unit previously. Do not extract more than one shelf at the same time, high risk of causing serious injuries to the operators due to the impact of the possible fall and/or trapping of the equipment. • Loosen the elements (PB) by hand turning them counterclockwise as far it would go with the floor and with the help of a spanner, loosen them half turn more in order to immobilize the metallic cabinet, having a correct levelling. Fig. 31 shows how the stabilizers elements (PB) have to be finally. 5.1.4.4. Preliminary considerations before connecting. • The description of this manual refers to the connection of terminals and switching manoeuvring that are only available in some versions or equipments with extended back up time. Ignore those operations regarding them, if the unit does not have them. • Follow and respect the instructions described in this section referred to the installation of a single equipment or parallel system. • Switchgear or external manual bypass panel boards: It is advisable to have an external manual bypass panel board equipped with input, output, static bypass (UPS-B version only) and manual bypass protections, in single installations. For parallel systems up to two units, it is very advisable having a switchgear panel board and for systems with 3 or 4 equipments, it is essential. Switches of the panel board have to allow isolating the UPS from the system against any wrong operating and feed the loads with the rest ones, either during the preventive maintenance period or the reparation of itself. • Under request an external manual bypass panel board for a single equipment or parallel system can be supplied. • Original position from factory of the element (PB). Element (PB) tighten against the floor. Fig. 31. Equipment / battery module stabilisers elements (PB). • Equipment maintenance and battery handling is a reserved task to the S.T.S. or authorized staff. If for any reason, the battery sliding shelves would need and intervention, it is essential to pay attention and respect the indications of the label sticked in each shelf, before extracting them (see Fig. 31). 30 If it’s required more detailed information for particular system configuration, ask for the relating «Recommended installation» information. In that information is shown the circuit diagram, as well as the protection size and minimum cross section of the wires that are connected to the equipment, taking into account the nominal operating voltage. All figures are calculated for a maximum total cable length of 30 m between the distribution panel board, equipment and loads. For longer lengths correct the cross sections accordingly, in order to avoid dropping voltages, by respecting the Regulations or norms corresponding to the country. In manual and for each setting, the information is available • • • • • • • • for «N» units in parallel, as well as the features of the own «Backfeed protection». In parallel systems, the length and cross section of the wires that goes from the panel board to the each UPS and vice versa, will have the same for all of them, without any exception. Always take into account the cross cable section, as regards to the size of the own terminals of the switches, in order to embrace all their section properly for an optimal contact between both elements. In the nameplate of the equipment, nominal currents are only printed as it states the EN-IEC 62040-1 safety standard. The input current calculation, has been done taking into account the power factor and the own efficiency of the equipment. If other peripheral elements are added to the UPS or parallel system input, output or bypass like transformers or autotransformers, take into account the currents stated in the own nameplates of those elements in order to use the suitable cross sections, always respecting the Local and/or National Low Voltage Electrotechnical Regulations. When a UPS or parallel system include a galvanic isolation transformer, as standard, option or installed by yourself, either at the input line, bypass line, output or in all of them, protections against indirect contact (RCD) have to be fitted in at the output of each transformer, because in case of electrical shock in the secondary winding (output of the isolation transformer), its isolating feature will block the tripping of the protections located in the primary winding. As a reminder, all isolation transformer installed or supplied from factory, has the output neutral connected to earth by means of a bridge that connects the neutral and earth terminals. In case, an isolated neutral were required, remove this bridge, by taking the precautionary measures stated in the respective local and/or national low voltage regulations. To enter the cables inside the cabinet, there are either cable glands (PR) assembled in the metallic structure or an only one opening as a register mode. Models with power rate higher than 40 kVA (LV) / 80 kVA (HV), have a rod to fix the connection wires of the equipment to it, by means of clamps (BF).

DB9 connector (X31) and (X32). • By default the equipment is supplied with 4 signal relays with a preset programming (see chart 2), which can be modified at factory or by teh S.T.S. under request. Chart 6 shows all the alarms that can be set to any relay. A fifth relay can be supplied as an option and under request, which can be defined in the purchase order. Also, there is a «Shutdown» input that allows turning off the inverter, when there is a voltage between (5÷ 12 V) at this input. • The most common use of these kinds of ports is to supply the necessary information to the file closing software. 35 terminal strip (X34) are supplied, to connect the battery temperature probe that allows compensating the floating voltage according to the ambient temperature. • Any wire connected to the terminals (X34), (X45) and (X51), will be entered into the equipment through the cable bushing (PR). 5.2.8. EPO terminals (X50). • All UPSs have two terminals to install an external emergency button to shutdown the output (EPO). • In case it was required to install a switch or button (EPO) in a single equipment, the cable bridge that closes the circuit has to be removed from terminal strip (X50) first. • For a parallel system, two different solutions can be applied, which are the following: Connect the button (EPO) in only one equipment of the parallel system. Remove the cable bridge from terminals (X50) in the equipment that it is only connected. 5.2.9.1. Terminal strip, auxiliary contact of manual bypass switch (X51). . • Terminal strip (X51) of two pins of the UPS, is connected in parallel with the normally opened auxiliary contact of the switch or manual bypass switch of the equipment. • Switchgear panel board with manual bypass manufactured by us (option), there is a terminal strip of two terminals connected in parallel with the normally opened auxiliary contact of the switch or manual bypass switch of the own switchgear panel board. Any auxiliary contact of the manual bypass are moved on in advance when closing. In case of fault and removing of the equipment that has physically connected the button (EPO), there is the risk of leaving the system without the emergency stopping, unless it is reconnected to the other operative UPSs. Connect a button (EPO) to each equipment of the parallel system. To do that, remove all the cable bridges from terminals (X50) in each equipment. Therefore, the functionality of the (EPO) will be kept in each one of them, regardless what occurs in the rest of equipments of the parallel system. By means of the own communication BUS among the equipments that make the parallel system, any action over any button will affect to the whole. • In any case, the switch or button (EPO) has to be normally closed (NC), so the emergency shutdown order will be triggered when opening the circuit between these terminals (X50). • In case of acquiring a switchgear panel board with manual bypass in another way, check that it has the stated auxiliary contact and connect it to the terminal strip (X51) of each equipment. As a must, the auxiliary contact has to be moved on in advance when closing. • It is ESSENTIAL as safety measure of the system, loads included, to connect the terminal strips (X51) of the UPSs with the terminal strip with the same functionality of the switchgear panel board. This way, any wrong action over any switch or manual bypass switch of the turned on UPSs will avoid causing a total or partial fault of the installation, loads included. To restore the UPS to normal mode, invert the position of the switch or button (EPO), -close the circuit between the terminals (X50)-, unblock the button. • To know the operating of (EPO), see section 6.6. of this manual. • The base of front door (PF) has a slot to facilitate the entering and way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it. (X50) 5.2.9.2. Terminal strip, auxiliary contact of output switch (X45). • This terminal strip of two pins is available in any equipment, but it is useful in parallel systems only. • Basically, the normally opened auxiliary contact of the output switch, is extended till the terminal strip of two pins (X45). Through the isolated cable as a bridge mode that is supplied connected between both pins, the circuit is closed. Do not remove in single equipments, because although the equipment would be in operation, there would be an alarm of output switch deactivated. • In those installations with parallel systems, the cable as a bridge mode connected between the two pins of the terminal strip (X45) of each UPS has to be removed, and connected to the terminals corresponding to the auxiliary contact of the output switch of the switchgear panel board. EPO (Output Emergency Shutdown) Fig. 36. Connection terminals for emergency shutdown switch or button (EPO), belonging to the end/user. 5.2.9. Auxiliary contact and battery temperature probe terminal strip. • • All the equipments are provided with terminal strip that corresponds to the auxiliary contacts of manual bypass (X51) and output (X45) switches. • Also in the equipments either with separate battery cabinet (models >20 kVA (LV) / >40 kVA (HV)), the additional 36 In case of acquiring a switchgear panel board by yourself, check if the output auxiliary contact is available and connect it to the terminal strip (X45) of each equipment. As a must, the auxiliary contact has to be moved on in advance when opening. See Fig. 6 to 14 for COM port physical layout. 5.2.9.3. Terminal strip, battery temperature probe (X34). For batteries in a separate cabinet only. • As the battery manufacturer recommends a variable floating voltage depending on the ambient temperature. The control of this feature will be done through the measurement of the temperature by means of a probe, located inside the cabinet itself when batteries and equipment are fitted in the same enclosure. For those cases that batteries are supplied in a separate cabinet out from the own UPS (models >20 kVA (LV) / >40 kVA (HV), there will be a terminal strip of two pins (X34), that allows bringing the probe located at the end of a two wires bundle with 4.5 m., till inside the battery cabinet. The connection of the two wires from the cable bundle to the terminal strip (X34) does not have polarity. • Also via this probe the ambient temperature inside the battery cabinet can be visualized in the control panel with LCD. • The bundle with the probe will always be supplied already connected to the terminal strip (X34), so it is only necessary to cut the clamp that keep it rolled, to take it out from the UPS cabinet and enter it into the battery cabinet, in both cases, through the foreseen cable bushing (PR). Fig. 37. Connection of the communication BUS. 5.2.10.1. Connection of the communication or BUS bundle (BC). . • Respect the sequence and connection order of the communication BUS among correlative equipments. Although the order of the connections of communication BUS among equipments are made, is not important, on condition that the communication loop is completed or closed properly, it is advisable to carry out the connections with the immediately next equipments in order simplify the connection. • The connection limit of the installation, will be determined by the quantity of available equipments to parallel and in any case till a maximum of four units. • Each equipment has two HDB15 connectors for the communications among them, one male labelled as “Output” (X36°) and another one female as “Input” (X36° ). i • In the same way, all the bundles supplied with the equipments, are equal in connections and length. 5.2.10. Connection of parallel BUS (X36i) and (X36o). • This section is only useful for parallel systems. • For the correct operation of the parallel functions and operating, any unit connected in parallel are continuously communicated among them. It is achieved by means of the called communication line or BUS. • Any operation of this section, regarding parallel systems, has to be done by authorised staff of our firm. • Once the power connections of the UPSs of the parallel systems are done, it is needed to make the ones related to the control or communication BUS. To do it, connect them in a sequential way, two lines of the communication BUS between a unit and its adjacent. • Together with each UPS of a parallel system, it is supplied a 15 wires bundle with HDB15 connectors at both ends, one male and the other one female, with a length of 5 m. Therefore, there will be as many communication BUS bundles (BC), as quantity of equipments to parallel have the system. DO NOT MODIFY THE COMMUNICATION BUS BUNDLE, OR THE CONNECTORS UNDER ANY CONCEPT. • Take one of the bundles and insert the HDB15 female connector located in one of its ends, into the male connector labelled as “Output” (X36° ), in any of the equipments of the system and insert the HDB15 male connector located in the opposite end of the bundle into the female connector labelled as “Input” (X36 i ) Of the adjoining equipment. • Repeat the previous step with each equipment of the system, till closing the communication BUS loop or ring. • As an example, Fig. 37 shows, how the communication BUS connections have to be done. 37 Although this illustration is not representative for the complete UPS series, as for the format of the cabinet, terminal layout or size and/or switches, as well as the own communication ports, it expects to be a guide to clarify the possible doubts on how the communication loop has to be connected. To see the physical layout of the COM connectors for each power rate, refer to the illustrations of figures 6 to 14. • The base of front door (PF) has a slot to facilitate the entering and way out of the communication cables inside the UPS. Watch to not trap them between the door and cabinet when closing it 38 6.1. 6. OPERATING. PRELIMINARY CONSIDERATIONS. • It is very important to always operate in the established order in the described instructions in the next sections, by respecting the sequence of the switches in relation to its function. So, i.e. in parallel system based on four equipments, when it is stated to turn on the «Input» mechanisms, the order of turning on them will not matter, but any other switch with different function as it could be «Output» switch will not be turned on, till is stated. • Unlike other UPS structures, where the «Master» and «Slave» equipments are preset strictly from factory, conditioning the order of start up and shutdown, the new UPS series is managed by a more flexible hierarchy according to the operating mode that it is. • During the description of this section, it is detailed the procedure to follow to get the different functionalities, considering a system of «n» equipments connected in parallel. If in your case, it is available only one UPS from UPS, series, proceed in the same order, but simplifying the operating for a single unit. • As it has been stated before, it is advisable to have an external manual bypass panel board equipped with input, output, static bypass (UPS B version only) and manual bypass protections, in single installations. For parallel systems up to two units it is very advisable having a switchgear panel board and for systems with 3 or 4 equipments, it is essential. Switches of the panel board have to allow isolating a UPS from the system against any wrong operating and feeding the loads with the rest ones, either during the preventive maintenance period or the reparation of itself. 6.2. START UP 6.2.1. Control before start up ˙ Carefully make sure that all the connections have been made correctly and are sufficiently tight, respecting the labelling of the device and the instructions of chapter «4.- Installation and wiring of the unit». Therefore it has been considered appropriate and naturally, to contemplate in the instructions of the equipment, the operating of a system with «n» equipments connected in parallel with their respective external manual bypass panel board as it is shown in the «Recommended installation» documentation included in the CD. This panel board allows isolating each equipment individually in case of fault and removing it without any difficulty for its reparation or replacement. Also, the included manual bypass switch makes easier the preventive maintenance tasks or intervention over the complete system, supplying the voltage to the loads directly from mains, on the «bypass» mode operating, mean- while the input voltage is available. In those installations without the external manual bypass panel board, omit the actions and steps that involve the manoeuvring of their switches. ˙ Check that the UPS switches and the batteries cabinet or cabinets are turned off (position «Off»). ˙ Be sure that all the loads are turned «Off». 6.2.2.

Powers according to model, configuration and operating voltage 57 9.2. • 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 color, (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 semicycles is used, or full wave, where both semi-cycles 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 circuit. GLOSSARY. • AC.- It is nominated as alternating current 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. Neverthe- less, some applications could need other period wave shapes, like triangular or square. • Bypass.- Manual or automatic, it is the physical junction between the input and the output electric device. • DC.- The direct current 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 from the highest potential point to the lowest one. Although, usually the direct current is identified with the con- stant current (for example the one supplied by the battery), it is continuous any current that always maintain the polarity. • DSP.- It is the acronym of Digital Signal Processor.A DSP is a system based on a processor or microprocessor that has instructions in it, a hardware and an optimized software to develop applications where numerical operations are needed with very fast speed. Due to this, it is very useful to process ana- logical 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 , being j the value of that angle. • GND.- The term ground, as its name states, refers to the potential of the earth surface. • 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, an interface (electronic) is the port (physical circuit) through which are sent or received signals from a system or subsystems toward others. 58
