3.2 Definition and structure.

3.2.1 Structural diagram.

Fig.10. M4T block diagram with operating flow.

M4T UPS may be used with main input and separate bypass line.

The most common required connection is the one with common main input and bypass. So both input terminals are short-circuited by shunt.

If final configuration is set with dual input please remove shunts between main input terminal and bypass line terminal (see figure below).

Input terminals

In equipment with separate bypass line, an isolation transformer must be placed at either or both of the UPS mains power supply inputs (rectifier input or static bypass), in order to avoid the direct connection of the neutral terminal with both mains through the internal wiring of the equipment.

This is only applicable if the power supply comes from two different electrical mains, for example:

- Two different electricity companies.

- An electricity company and a generator set, etc.



11

3.3 Operating principle.

The M4T UPS series is a double conversion system AC/DC, DC/AC with a sine wave output that gives safe protection in extreme power supply conditions (variations in voltage, frequency, electrical noises, blackout and micro cuts, etc…). Regardless of the type of load to be protected, these devices are designed to ensure a quality and continuous power supply.

The operation is as follows:

An IGBT three phase rectifier converts the AC voltage into DC by absorbing a pure sine wave current

(THD <2%) and charging batteries at constant current / voltage.

The batteries supply the power needed by the inverter in the event of mains failure.

The basic double conversion structure is complemented by two new functional blocks, the static bypass commuter switch and the manual bypass commuter switch.

The static bypass commuter switch connects the output load directly to the bypass network in special circumstances such as overloading or overheating and reconnects it to the Inverter when normal conditions are restored.

The standard version has separate lines for the Inverter and bypass blocks, thus increasing the safety of the installation as it allows the use of a second power supply (generator unit, other electricity company, etc.).

The manual bypass commuter switch isolates the UPS from the mains and from the loads connected to the output, so that maintenance operations may be performed on the UPS without any need to interrupt the supply to the loads.

3.3.1 Normal operation, ().

When there is a mains power supply, the rectifier transforms the AC input voltage into DC raising the DC voltage to a suitable level to supply the inverter and to charge the batteries.

The inverter transforms the voltage of the DC bus into AC, providing a sine wave alternating output, stabilized in voltage and frequency to supply the loads connected to the output (figure 10).

3.3.2 Operation with mains failure, ().

In the event of mains failure or should a micro cut occur, the group of batteries supplies the power needed to supply the inverter.

The inverter continues working normally without being affected by the lack of mains and the back-up time of the device depends only on the capacity of the group of batteries (figure 10).

When the battery voltage reaches the end of back-up time, the control blocks the output to protect against deep battery discharge.

When mains is restored and after the first seconds of analysis, the UPS again operates as described in the

“Normal operation” section.

3.3.3 Operation with inverter not active, ().

The inverter is inactive due to the existence of alarm conditions such as overloads, overheating, end of back-up time, etc. In this case the rectifier continues charging the batteries to maintain the optimal charge.

The inverter is also inactive if the unit has not been started up with the keyboard. In that case, the rectifier will be inactive.

In all these cases the output voltage of the UPS is supplied by the emergency bypass line through the static bypass commuter switch (figure 10), provided that the EPO is inactive

3.3.4 Operation in manual bypass, ().

When maintenance checks are to be performed on the device, it may be disconnected from the mains without any need to cut the power supply to the system and affect the critical load. The UPS may only be worked on by technical or maintenance personnel, by means of the maintenance bypass (as per specific instructions for that purpose).

4 INSTALLATION

Check the Safety Instructions.

Make sure that the data on the characteristics plate are those required for the installation.

Any incorrect connection or handling may cause damage to the UPS and/or the loads connected to it. Read these instructions carefully and follow the steps in the order indicated.

This UPS must be installed by qualified staff but can be used by personal with without any specific preparation aside from this “User Guide”.

4.1 Important Safety Instructions.

As this is a device with class I protection against electric shocks, it is essential to install a protective earth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting the power supply to the UPS input.

All connections to the device, including those for control (interface, remote control, etc.), will be performed with the switches in the off position and without any mains present (UPS power line cut off “Off”).

It should always be remembered that the UPS is a generator of electrical power, so users must take all necessary precautions against direct or indirect contact.

Warning labels should be placed on all primary power switches installed in places that are not in the vicinity of the device to alert the electrical maintenance personnel of the presence of a UPS in the circuit.

The label will bear the following or an equivalent text:

Before working on this circuit.

- Isolate the Uninterruptible Power Supply (UPS).

-Then check for Hazardous Voltage between all terminals including the protective earth.

Risk of Voltage Back feed

When the power supply reaches the UPS input with static bypass included, although the inverter is “Off” (shutdown), it does not mean there is no output voltage at the output terminals.

To do this, (Q1a), (Q4) and (Q2) must be switched to the “Off” position.

The UPS may be supplying output voltage from the manual bypass which must be taken into account for safety purposes. If the output power supply of the UPS has to be interrupted in this situation, deactivate the switch

(Q5).

Precautions must be taken for devices with battery terminals, as they are not isolated from the alternating input line, and there could be dangerous voltage between the battery terminals and the ground.

4.1.1 Batteries.

Batteries should be handled and connected or supervised by qualified personnel with battery knowledge.

For units supplied without batteries, the batteries will always acquire, installed and connected by the customer and under his responsibility. The battery details (number, capacity and voltage) are indicated on the battery label pasted beside the nameplate of the equipment. These requirements should be strictly adhered to as well as the battery polarity connection and the circuit diagram provided with this documentation.

The battery supply may involve the risk of electric shock and may produce high short circuit current. Please observe the following preventive measures before manipulating any terminal block identified on the label as

“Battery”:



13

Disconnect the corresponding protection components.

When connecting a battery cabinet to the equipment, the cable’s polarity and color (red-positive; blacknegative) indicated in the manual and in the corresponding labeling must be adhered to.

Wear rubber gloves and shoes.

Use tools with insulated handles.

Remove watches, rings or other metal objects.

Do not place metal tools or objects on the batteries.

Never handle with your bare hands or through conducting objects as this may short-circuit the battery terminal block or the battery enclosure.

 Never short-circuit the battery terminals as it involves high risk and will be detrimental to the equipment and batteries.

 Avoid mechanical stress and impacts.

 Do not open or mutilate the battery. Released electrolyte is harmful to the skin and eyes.

 Do not dispose of batteries in a fire. The batteries may explode.

 In the event parts of the body come into contact with battery acid, wash immediately with plenty of water and call the nearest medical service as soon as possible.

 Batteries involve a serious risk for health and the environment.

 They should be disposed of according to current laws.

4.1.2 Account access.

Once the UPS is connected, replace the cover (TB) and close the door (PF) with the lock (CL).

 The cable cross section of the bypass, input and output lines shall be determined from the maximum currents for the first two and from nominal ones for the output, by respecting the local and/or country Low

Voltage Electro-technical standards.

To calculate the cross cable sections, take the figures of the current given in tables 1 or depending on the model, single or three phase configuration and nominal voltage value of the UPS.

The equipment nameplate only gives the nominal currents as stated in safety standard EN-IEC 62040-1.

 The protections in the distribution board will have the following characteristics:

For the input and bypass lines, type B earth leakage breakers and curve C circuit breakers.

For the output (supply loads), curve C circuit breaker.

 If input, output or bypass peripherals such as transformers or autotransformers are added to the UPS, currents stated on the nameplates of those components have to be taken into account, in order to use the suitable cross sections, by complying with the Local and/or National Low Voltage Electro-technical

Regulations.

 When a piece of equipment has a galvanic isolation transformer, as standard, as an option or installed by the end user, at the UPS input, bypass, output line or in all locations, they have to be fitted with protections against indirect contacts (earth leakage breaker) at the output of each transformer, because its own isolation feature will impede the tripping of protections installed at the primary winding of the transformer in case there is an electric shock in the secondary winding (isolation transformer output).

 May we remind you that all isolation transformers supplied or installed from factory have the neutral cable connected to the ground through a cable bridge between the neutral and ground terminals. If you require an isolated output neutral, please remove this bridge, taking the stated precautions to comply with local and/or national low voltage standards.

 The supplied cable passages fitted to the metal structure are those recommended to correctly attach the input, output and bypass wires with the sections determined by the National Low Voltage Electro-technical

Regulation in accordance with the currents of the device.

If these sections have to be changed for any reason, it should be done from a separate distribution box and the sections indicated should be maintained from the device to the distribution box.

 In standard equipment up to 40 kVA, batteries are supplied inside the UPS enclosure and for higher power rates; they are supplied in a separate cabinet. By default, the UPS has a battery fuse-holder switch (Q3) with 3 fuses for models up to 40 kVA or battery switch (Q3) for models with higher power rate. The battery cabinet has a fuse holder switch (Q8) with 3 fuses, for both models with a higher power rate of 40 kVA and for extended back up times. fuse holder switch (Q3) or (Q8), install the 3 fuses and WAIT until it is

indicated before CLOSING IT.

IMPORTANT FOR YOUR SAFETY: Do not turn the battery fuse holder switch (Q3) or (Q8) located in the battery cabinet to “On” (Close), until the equipment is switched on completely because it may cause irreversible damage to the equipment or accidents.

 Then shut down the device, disconnect it and keep the UPS and the battery cabinet(s) in their original packaging, noting the new battery charge date on the respective labels.

 Do not store the unit where the ambient temperature exceeds 40ºC or falls below -20ºC, as this may deteriorate the electrical characteristics of the batteries.

4.2.3 Transport to location.

 All UPS devices have castors to facilitate their transport to their final location. It is important to abide by the approximate weight requirements indicated in tables 5 and 6 both with respect to the site itself and the installation means (floor, hoist, lift, stairs, etc.).

4.2.4 Location.

 The Safety Instructions indicate that a minimum of 25cm clearance should be left around the equipment for ventilation purposes. However an additional 75 cm is recommended to facilitate maintenance operations or technical assistance in the event of breakdown (see figures 11 and 12).

 The UPS may be put in any place as long as the Safety Instruction requirements are fulfilled and the weight requirements indicated in table 7 and 8 are complied with.

 The UPS includes 2 leveling components (PB) located near the front castors, which immobilize the unit once in place.

Open the front door (PF) of the cabinet and proceed as follows:

- Lower the feet (PB) by hand by turning them anticlockwise until they touch the floor, and then, using a spanner, continue loosening until the castors are raised off the floor by a maximum of 0.5 cm, ensuring that it is level.

-Close the door (PF).

4.3 Connections.

4.3.1 Mains terminals (X1 to X4).

 As this is a device with class I protection against electric shocks, it is essential to install a protective earth conductor (earth connection ( )). Connect the conductor to the terminal (X5), before connecting the power supply to the UPS input.

 In accordance with safety standard EN-IEC 62040-1, the installation has to be provided with a “Backfeed protection” system.

For example a contactor, which will prevent the appearance of voltage or dangerous energy in the input mains during a mains fault (see figure 13)

There can be no bypass in the line that goes from the “Backfeed protection” to the UPS, as this would infringe on standard safety requirements.

Warning labels should be placed on all primary power switches installed in places that are not in the vicinity of the device to alert the electrical maintenance personnel of the presence of a UPS in the circuit.

When there are discrepancies between the labelling and the instructions of this manual, the label will always prevail.

In equipment with a separate bypass line, an isolation transformer must be placed at either or both of the

UPS mains power supply inputs (rectifier input or static bypass), in order to avoid the direct connection of the neutral terminal with both mains through the internal wiring of the equipment.

This is only applicable if the power supply comes from two different electrical mains, for example:

- Two different electricity companies.

- An electricity company and a generator set, etc.

4.3.3 Output, terminals (X6 to X9).


 Connect the output cables to the respective terminals according to configuration of the available equipment.

Three phase output:

Connect the load cables N-U-V-W to the output terminals (X9), (X6), (X7) and (X8), adhering to the order of neutral and phases indicated on the label of the device and in this manual. When there are discrepancies between the labelling and the instructions of this manual, the label will always prevail.

 With respect to the compulsory protection on the UPS output, we recommend that the output power should be distributed in at least four lines. Each has a magnetic thermal protection switch with a value equivalent to a quarter of the nominal power. This type of power distribution means that only the faulty line will be affected in the event of a breakdown in any of the machines connected to the device resulting in a short circuit. The rest of the connected loads will have their continuity ensured due to the triggering of the protection, only the line affected by the short circuit will remain.

4.3.4 UPS connection to each in-cabinet battery pack, terminals (X11, X12, X23) & (X47, X48,

X49).


 IMPORTANT FOR YOUR SAFETY: Do not turn the battery fuse holder switch (Q3) or (Q8) located in the battery cabinet to “On” (Close), until the equipment is switched on completely, it may cause irreversible damage to the equipment or accidents because the fitter is exposed to ELECTRICAL DISCHARGE DANGERS when connecting the UPS with the battery cabinet.

 The UPS with battery pack will be connected, by connecting one side to terminals (X11), (X23) and (X12) of the UPS and the other to terminals (X47), (X49) and (X48) of the battery pack, while adhering to the stated polarity on the labelling of each part and in this manual, and the color of the cables (red for positive, black for negative, blue for middle tap (N) and green-yellow for earth bonding), see figure 14.

 Keep in mind that if more than one battery pack is supplied, the connection will always be in parallel with the equipment. For instance, the black cable from the UPS negative terminal to the negative of the first battery pack and from this one to the negative of the second battery pack, and so on. Please, proceed in the same way for red cable for positive, blue for half tap (N) and green-yellow for earthing.

 Electrical discharge danger. If after starting up the UPS, the battery cabinet needs to be disconnected, the equipment has to be completely shut down (see section 5.2). Turn off the battery fuse holder switch (Q8) located in the battery cabinet and/or fuse holder switch or switch (Q3) located in the

UPS. Wait at least 5 min. until the filter capacitors have been discharged.

4.3.5 Main protective earthing terminal ( ) & protective earth bonding terminal ( ).


 Make sure that all the loads connected to the UPS are only connected to the protective earth bonding terminal ( ). The fact that the earthing of the load(s) and/or the battery case(s) or cabinet(s) is not restricted to this single point will create return loops to earth which will affect the quality of the power supplied.

 All of the terminals identified as protective earth bonding ( ), are joined together and to the main protective earthing terminal ( ) and to the frame of the device.

4.3.6 COM port to relay. Connector (X32).

 The communications line (COM) represents a very low safety voltage circuit. To maintain the quality, it must be installed away from other lines that have dangerous voltages (power distribution line).

 The communication port to relays provides digital signals in the form of potential free contacts with a maximum applicable voltage and current of 6 A 30 V DC or 6 A 100 V AC. Both channels are used to connect the UPS to any machine or device that has this standard bus (connector DB9 (X32)).

 In standard units, there are 5 output signalling relays (one of which can be configured), whose common point is connected to pin 5. Also an input signal can be externally supplied to perform Shutdown (5V~12V).

 The most common use of these kinds of port is to supply the necessary information to the file closing software.

4.3.7 Port COM RS-232 & RS-485. Connector (X32).

 The communications line (COM) represents a very low safety voltage circuit. To maintain the quality, it must be installed away from other lines that have dangerous voltages (power distribution line).

 Both of the equipment’s communication ports, RS-232 and RS-485, are in the same connector DB9. It is not possible to use them simultaneously.

 Both channels are in use to connect the UPS with any machine or device that has this standard bus. The

RS-232 transmits serial data, so it is possible to send a large amount of information through a communication cable with just 3 wires.

 Physical structure of the RS-232.

Pin-out

- Pin 2. RXD. Serial data reception.

- Pin 3. TXD. Serial data transmission.

- Pin 5. GND. Signal mass.

Communication protocol of the RS-232.

The communication protocol used is a “MASTER/SLAVE” type. The computer or computer system (“MASTER”) asks for certain data, and the UPS (“SLAVE”) answers immediately with the required data.

Firstly, the computer communication channel will be programmed with the same parameters as the UPS communication channel.

Then the communication can begin and the UPS is sent the first question.

If a problem occurs during the communication, it is advisable to repeat the channel initialization sequence.

 Physical structure of the RS-485.

Unlike other serial communication links, this uses only 2 wires (pins 4 and 9 of the female DB9 connector) to perform the dialogue between the systems connected to the network. The communication will be established by sending and receiving signals in differential mode, which gives the system great immunity to noise and a long reach (approx. 800 m).

Pin-out

- Pin 4. RS-485 output signal A (+).

- Pin 9. RS-485 output signal B (–)²².

Communication protocol of the RS-485.

The communication protocol of the RS-485 channel is developed to enable the UPS to dialogue with other computer systems that have this kind of channel.

22



 The RS-232 and RS-485 communication parameters are as follows:

Communication speed: 1200, 2400, 4800, 9600 or 19200 Bauds.

No. information bits: 8 Bits.

No. stop bits: 1 or 2 stop bits.

Parity: - Even, Odd or None.

4.3.8 EPO terminals (X50).

The equipment has two terminals ready for external (remote) Emergency Power Off (EPO).

If a switch or button (EPO) has to be installed, the cable bridge that closes the circuit has to be removed from terminal strip (X50).

The switch or button (EPO) has to open the circuit between the terminal strip (X50) to activate the emergency shutdown. To restore the UPS to normal mode, invert the position of the switch or button (EPO), and close the circuit in terminal strip (X50).

For information on EPO operation, see section 5.3 of this manual.

5.4 Bypass manual switch (MAINTENANCE).

5.4.1 Operating principle.

The UPS integrated manual bypass is a very useful feature, but undue use can have irreversible consequences both for the UPS and for the loads connected to its output. It is therefore important to handle it as described in the following paragraphs.

5.4.2 Transfer to manual maintenance bypass.

Procedure for passing from normal operation to maintenance bypass:

 Shut down the inverter. Go down to the “CONTROL & STATUS OF THE UNIT” submenu (screen 1.0) using the control panel keypad ((3) from figure 19), and then right once only. Screen 1.3 will appear asking you to shut down the unit by pressing (ESC). Do so, and then confirm the operation by pressing (ESC). Do so, and then confirm operation by pressing (ENT), see figure 18.

 Remove the screws fastening the mechanical block (BL).

 Remove the mechanical block (BL) of the manual bypass switch (Q5) and set it to the “On” position.

 Set the output switch (Q2) to the “Off” position.

 Set the Battery Fuse Holder or battery switch (Q3) to “Off”. In addition, in models with independent battery pack(s) also turns Battery Fuse Holder (Q8) of each pack to “Off”.

 Set the input switch (Q1a) and static bypass switch (Q4) to the “Off” position.

The UPS supplies output voltage through the manual bypass. The UPS is fully shut down and inactive.

5.4.3 Transfer to normal operation

Procedure for passing from maintenance bypass to normal operation:

 Set the input switch (Q1a) and static bypass switch (Q4) to the “On” position.

 Set the output switch (Q2) to the “On” position.

 Set the manual bypass switch (Q5) to the “Off” position and refit the mechanical block (BL) and the screws

(t2).

It is an essential safety requirement, for the life of the UPS and the loads connected to it, to refit the mechanical block (BL) as this avoids dangerous handling.

 Start up the inverter. Go down to the “CONTROL & STATUS OF THE UNIT” submenu (screen 1.0) using the control panel keypad ((3) from figure 19), and then right once only. Screen 1.1, asking you to start the unit up by pressing (ENT). Do so, and then confirm operation by pressing (ENT) again. See following screen diagram (figure 18).

The UPS supplies output voltage entirely protected against voltage variations, electric noise, etc.

7 Maintenance, warranty and service

7.1 Basic maintenance guide.

Batteries, fans and capacitors must be replaced at the end of their useful lifetime.

Inside the UPS there are dangerous voltages and metallic parts at very high temperatures, even after the UPS is shut down. Direct contact can cause electrocutions and burns. All operations, except battery fuse replacement, must be done by authorized technical staff.

Some internal parts of the UPS (terminals, EMC filters and measurement circuits) are still under voltage during the maintenance bypass operation. To cancel all voltages, the mains and bypass circuit breakers on the panel supplying the UPS and the external battery cabinet fuse holders have to be turned ”OFF“ /

”0“. The internal batteries must also be isolated from the system.

7.1.1 Battery fuses.

Turning on the battery switch or fuse holder according to power of the equipment (“ON” or “I” position) before alarm message “BATT. SWITCH OPEN, SWITCH IT ON” is displayed on the LCD panel can blow the battery fuses or switch.

The battery fuses can only be replaced by ultrafast models type Gould aR 660V (14x51 or 22x58 mm, depending on the unit model) of the same dimensions and rating.

7.1.2 Batteries.

The useful lifetime of the batteries depends on the ambient temperature and other factors such as the quantity of charging and discharging cycles and full discharges.

The average lifetime is between 3 and 5 years if the ambient temperature is between 10 and 20ºC. For more information of its status, activate the battery test.

There is a risk of fire and/or explosion if the wrong quantity or type of batteries is used. Do not dispose of the batteries in a fire: they can explode. Do not open or mutilate the batteries: the dumped electrolyte is dangerous for the skin and eyes. It can be toxic.

7.1.3 Fans.

The useful lifetime of the fans used to cool the power circuits depends on the use and surrounding conditions.

8.2 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 sine wave, because the energy transmission is better. Nevertheless, 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 and AC - 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 constant current (for example that supplied by the battery), any current that always maintains the polarity is said to be continuous.



45

DSP - It is the acronym for Digital Signal Processor. A DSP is a system based on a processor or microprocessor that has instructions in it, hardware and optimized software to develop applications where very fast numerical operations are needed. 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 from an analogical/digital converter (ADC).

Power factor - The power factor, p.f., of an alternating current circuit, is defined as the ratio between the active power, P, and the apparent power, S, or as the cosine of the angles that make the current and voltage vectors, designating as Cos φ, being the value of that angle.

GND - The term ground, as its name states, refers to the potential of the earth’s surface.

IGBT - The Insulated Gate Bipolar Transistor is a semiconductor used as a controlled switch in powered 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 the switch in a single device. The triggering circuit of the IGBT is the same as

MOSFET one, while the driving features are like the BJT.

Interface - In electronics, telecommunications and hardware, an interface (electronic) is the port (physical circuit) through which signals are sent or received from a system or subsystems toward others.

kVA - The volt-ampere is the unit of the apparent power in electrical current. In direct current it is almost equal to the real power but in alternating current it can differ depending on the power factor.

LCD - Acronym of Liquid Crystal Display. 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 direct light passing through.

LED - Acronym of Light Emitting Diode, the LED is a semiconductor (diode) that emits almost monochrome light with a very narrow spectrum, i.e. 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 ultraviolet going through the visible spectrum of light to infrared. The latter type is called 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 exceeds the maximum set values.

On-Line mode - A piece of equipment 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 magnitude and frequency required by the user or the designer.

Rectifier - In electronics, a rectifier is the component or circuit that allows the alternating current to be converted into direct current. This is done by rectifier diodes, which can be solid state semiconductors, vacuum or gassy valves such as the mercury vapour. Depending on the features of the alternating current power supply used, it is classified as single phase when supplied by a single phase electrical mains, or three phase when supplied by the three phase power. Depending on the rectification type, a rectifier can be half wave, when only one of the current semi-cycles is used, or full wave, where both semi-cycles are used.

Relay - The relay (in French “relais”) is an electromechanical device that works like a switch controlled by an electric circuit where, through an electromagnet, a set of contacts is moved.

8.3 Safety Instructions

8.3.1 TO PROVIDE FOR.

• These “Safety Instructions” are associated with the “Operating Manual” regarding the equipment you have purchased. Before proceeding with the installation or start-up, check that you have both sets of information, if not, ask for them. Compliance with the “Safety Instructions” is compulsory and is the user’s legal responsibility.

Read them carefully, follow the steps in the given order and keep them for future reference. The local electrical standards and different restrictions of the end user’s city may invalidate some of the recommendations given in the manuals. In case of discrepancies, the user must comply with the pertinent local standards. The situation may arise where the equipment’s distribution of connecting terminals and/or commands do not line up with the manual’s illustrations. However, the simplicity of the operation together with the correct labelling provides for easy understanding in an intuitive way.

• It is strictly forbidden to reproduce or to release this information without written permission from our company.

• Do not install the machine in a corrosive or dusty atmosphere, and never outdoors.

• Do not obstruct the ventilation grates nor introduce objects through these or other orifices. Leave a minimum free space of 25 cm around the machine for ventilation and air circulation.

• The location must be spacious, airy, away from heat sources and easily accessible. In addition to the ventilation space indicated above, there must be an area of 75 cm clearance all-round the device for possible action by the After Sales Service (A.S.S.), so that if this involves moving the machine the connecting cables will have the required space.

• Do not place materials on top of the machine or objects which would obstruct a proper view of readings.

8.3.2 GENERAL SAFETY INSTRUCTIONS.

• All equipment connections including those of the control should be done without the presence of the mains supply and with the switches turned off, position “On”, “Off”, or respectively.

• Special attention should be paid to the labelling on the equipment warning about the “Risk of electric shock” and indicators like ( ). Hazardous live parts inside the equipment, do not remove the cover. Servicing is reserved for qualified service personnel. For maintenance or repair services, contact your nearest After Sales

Service (A.S.S.) in our company.

• It is compulsory to connect the earth protection. Make sure that this is done before powering up the input to the equipment.

For small equipment (input power cord provided with plug), the user should make sure that the wall outlet’s voltage corresponds to the type delivered, properly grounded and connected to the local protection earth. For equipment fitted with terminals, the licensed wirer should connect the earth wire to the terminal identified as

( ).

• The installation of hard wired equipment should be done by personnel qualified in electrical low voltage installations.

• The cross section of the power supply and output cables to the loads should be determined according to the rated current given on the equipment’s specifications plate and comply with the Local Low Voltage Electro technical Regulations.

• The power supply cables to the equipment as well as to the loads, interfaces, etc. should be fastened to nonmovable parts to prevent pulling.



47

• Please keep in mind that if the equipment incorporates a Bypass with mains power available it will supply output voltage even if the equipment is not turned on. Place warning notices and /or emergency switches as requested by the safety Regulations of your specific installation.

• The voltage stabilizers and line conditioners should be considered as transformers or distribution lines from the point of view of the installation and of the electrical safety. This equipment is “transparent” to the input voltage.

• The Neutral input of the three phase equipment should be necessarily connected to the terminal intended for this purpose.

• The phase to phase voltage at the output may not be the same on the three phase voltage stabilizer and line conditioners with independent phase regulation with unbalanced voltage from the three phase input supply on the loads, however the phase to neutral regulation will be kept.

• The line conditioners (voltage stabilizers fitted with galvanic isolation transformer) can be connected with the desired neutral condition. The wire bridge going from one output terminal (neutral) to the ground terminal can be deleted for the isolated neutral condition.

• The servo-motor voltage stabilizers and line conditioner incorporate mechanical components (gearing, dented belts, etc.) Do not service inside the equipment as the motion during the regulation may cause personal injuries.

• Devises mounted on CHASSIS or RACKS for the installation on pre-determined assembly units is intended to be done by professionals.

- Your installation should be planned and carried out by qualified personnel, who will be responsible for applying the safety and EMC legislation as well as standards regulating the specific installation where the product is to be used.

- CHASSIS mounted equipment has neither enveloping protection nor connecting terminals.

- RACK mounted equipment has no connecting terminal protection.

8.3.3 SAFETY INTERACTIONS FOR BATTERY EQUIPPED PRODUCTS.

• The UPS are continuous supply equipments. If the mains supply fails while the equipment is operating, the output lines will continue supplying output voltage depending on the autonomy provided by the battery.

• Generally batteries are already fitted in a single cabinet except in specific situations where, for various reasons, they are delivered inside a separate enclosure.

• For proper operation the battery cabinet must be located beside the machine.

• The battery supply can involve the risk of electric shock and can produce high short circuit current. Observe the following preventive measures before handling any terminal block identified in the labelling as “Battery”.

- Disconnect the corresponding protection components.

- When connecting a battery cabinet to the equipment abide by the cable polarity and color (red-positive; black-negative) indicated in the manual and by the corresponding labelling.

- Wear rubber gloves and shoes.

- Use tools with insulted handles.

- Remove watches, rings or other metal objects.

- Do not place metal tools or objects on the batteries.

- Never touch with your hands or through conducting objects, do not short the battery terminal block or the battery enclosure.

• To prevent full battery discharge and as a safety measure after an extended power failure, as well as at the end of the daily work, you should turn off the loads and later the equipment according to the operation given in the “Operating Manual”.

• For extended periods of disconnection connect the equipment every month for at least 12 hours to charge the battery, to prevent any irreversible deterioration. When storing the equipment, place it in a cool and dry location, never outdoors.
