I

NSTALLATION ENVIRONMENT

When selecting the installation site of the UPS and any Battery Boxes, observe the following notes:



The UPS / Battery Box must be installed at a suitable distance from walls and other obstacles. For further information, refer to the included

“Installation Instructions”

 avoid dusty environments

 ensure that flooring is flat and able to sustain the weight of the UPS (and Battery Boxes)

 avoid environments that are too narrow which might prevent normal maintenance operations

 relative humidity must not exceed 90%, without condensation

 verify that the room temperature, with the UPS in operation, is maintained between 0 and 40°C

The UPS is able to operate at a temperature between 0 and 40°C. The recommended operating temperature for the UPS and the batteries is between 20 and 25°C. The actual operating life of the batteries is 5 years on average at an operating temperature of 20°C. If the operating temperature reaches 30°C, the operating life is halved.

 avoid positioning the UPS in places which are exposed to direct sunlight or to hot air

To maintain installation room temperature in the above indicated range, waste heat disposal should be provided for (the value of kW/kcal/h/ B.T.U /h dissipated by the UPS is shown in the table in the included "Installation Instructions").

Methods which can be used include:



natural ventilation



forced ventilation, recommended if the external temperature is lower (e.g. 20°C) than the temperature at which you want to operate the UPS and/or the Battery Box (e.g. 25°C)



air conditioning system, recommended if the external temperature is higher (e.g. 30°C) than the temperature at which you want to operate the UPS and/or the Battery Box (e.g. 25°C)

UPS S

TORAGE

The storage site must meet the following requirements:

Temperature: -25°÷60°C

Degree of relative humidity: 30÷95% max

E

LECTROMAGNETIC COMPATIBILITY

This UPS complies with applicable EMC (Category C3).

CAUTION:

This product is designed for second environment* commercial and industrial applications - it may be necessary during installation to introduce certain restrictions and take additional measures to prevent disturbances.

Connection to USB and RS232 connectors must be made with the supplied cables or, however, with shielded cables that are no longer than 3 metres.

(*) Type of environment defined in EMC regulations

O

VERVOLTAGE PROTECTION

The UPS has been designed to be powered by an AC mains supply with category 2 voltage spikes. if it connected to an AC supply with different characteristics or if it is potentially subject to even transitory overvoltage, external protection equipment must be installed to it.

A

IR EXCHANGE IN THE BATTERY ROOM

The room in which the battery box is installed must be provided ventilated so as to keep the concentration of hydrogen generated during charging within safe limits.

The room should preferably be ventilated naturally; if it cannot be, forced ventilation may be employed.

Standard EN 50272-2 regarding air exchange provides that the minimum aperture must satisfy the following equation:

A = 28 x Q = 28 x 0.05 x n x Igas x C10 (1/10³) [cm²]

where: A = surface free of air input/output opening

Q = air flow to be exhausted [m³/h] n = number of battery elements;

C10 = battery capacity in 10 hours [Ah]

Igas = gas producing current [mA//Ah] according to the standard:

Igas = 1 in backup charging for VRLA type batteries (*)

Igas = 8 in fast charging for VRLA type batteries (*)

(*) for open vessel or nickel batteries, contact the battery manufacture for details.

- example calculation

Type of battery: VRLA

Number of elements: 240 (40 mono-blocks)

Capacity: 120Ah

Igas (**): 8 (fast charging)

A = 28 x Q = 28 x 0.05 x n x Igas x C10=28 x 0.05 x 240 x 8 x 120 x 1/10³ = 322 cm

2

(**) to increase the safety margin, we take the fast charging condition, well aware that the battery mostly runs in backup charging mode. Using the backup charging value for Igas would result in a value of one eighth of the above.

The air intake/outlet must be located so as to be most favourable to circulation, e.g.:

- openings on opposing walls

- with a minimum distance of 2 m if both on the same wall.

RELIMINARY OPERATIONS FOR CONNECTION

The following operations are to be performed with the UPS disconnected from the power mains, off and with all equipment switches open. Before making the connection, open all machine switches and verify that the

UPS is completely isolated from its power sources: AC mains and battery. In particular, check that:

- the UPS input line is completely disconnected

- the separate bypass line (if present) is completely disconnected;

- the external UPS battery line switch/fuses are open

- all UPS switches: SWIN, SWBYP, SWOUT and SWMB in the open position

- check with a Multimeter that there are no dangerous voltages

The first connection to be made is the protective conductor (earth wire), to be connected to the screw marked PE. The UPS must operate while connected to the earthing system.

The input Neutral must always be connected.

CAUTION: a three-phase 4 wire distribution system is required.

The standard UPS version must be connected to a 3 Phase + Neutral + PE (ground protection) TT, TN or IT type power line. Comply with the phase rotation specification.

TRANSFORMER BOXES (optional) are available to convert distribution systems from 3-wire to 4-wire.

CAUTION: in the event of non-linear three-phase loads, the Neutral conductor (N) current can reach a value

up to 1.7 times that of the phase current. Properly size the Input/output Neutral line keeping this fact in mind.

Carefully read instructions contained in the Battery Box manual before connecting batteries.

Check that battery voltage is the same as allowed by the UPS (consult the Battery Box data plate and the

UPS manual)

CAUTION: the maximum length of the connection cables to the Battery Box is 10 metres

UPS

CONNECTIONS

Follow the instructions below in order:

 remove the IN/OUT connection access panel on the back of the device (see "UPS rear views")

CIRCUIT PROTECTION

In the presence of a fault on the load, the UPS limits the value and duration of the output current (short circuit current) for protection. These values are also functions of unit status at the time of the fault. Two different cases can be distinguished:



UPS in NORMAL OPERATION: the load is instantly switched to the bypass line (I

2 t=432000A

2 s): the input line is connected to the output without any internal protection (it locks out after t>0.5s)



UPS in BATTERY-LED OPERATION: the UPS protects itself by sending a 2.7 times nominal current to the output for the first 0.2s, which is then reduced to 1.5 times nominal for 0.3s. After this time (>0.5s) it switches off.

P

ROTECTION AGAINST BACK

-

FEED

The UPS is equipped with a device to prevent voltage backfeed to the input line when internal faults occur. During inverter operation, if an internal fault occurs which causes backfeed on the bypass line, the protection switches off the inverter and switches the load to the bypass. If the fault occurs with the UPS in battery operation, the load remains unpowered.

To prevent the inverter switching off and hence keep the load powered by the inverter even if a double fault occurs (mains power failure and internal fault), the system can be customised to control the opening coil of an upline switch by reprogramming one of the relays on the comms board.

The control logic allows you to reconfigure the relays, for example for a backfeed alarm, and use the no voltage contact t o actuate a switch upline of the UPS itself.

I

NPUT LINE THERMAL MAGNETIC SWITCHES

Install a trip switch with C (or D, depending on the type of load) trip curve on the power supply line upstream of the UPS.

FOR FURTHER INFORMATION, REFER TO THE INCLUDED "INSTALLATION INSTRUCTIONS"

B

ATTERY LINE

A surge protector and a cut-off device must be provided on the UPS external battery line.

The size and type of fuses must be selected on the basis of the capacity of the installed battery box, referring to the table in the included "Installation Instructions".

D

IFFERENTIAL

In the absence of an input separating transformer, the neutral from the mains power supply is connected to the neutral of the

UPS output. This way the neutral regime of the equipment is not modified.

THE INPUT NEUTRAL IS CONNECTED TO THE OUTPUT NEUTRAL  THE DISTRIBUTION SYSTEM THAT POWERS THE

UPS IS NOT MODIFIED BY THE UPS

CAUTION: make sure that the equipment is connected correctly to the input neutral, or else damages to the

UPS may be caused.

The circuit neutral is only affected if an isolating transformer is present or the UPS is operating with the neutral disconnected upstream.

DUAL INPUT versions: the neutral for the input line and bypass line are shared inside the device.

A single differential switch must be fitted upstream of the point at which the line divides to supply the trip switchprotected rectifier and bypass inputs for the UPS. See following diagram:

PARALLEL versions: In order to prevent false activations where several machines are connected in parallel, a single differential switch should be fitted upstream of the entire system. See following diagram:

When operating from mains power, a differential switch located at the input can intervene as the output circuit is not isolated from the input circuit. Anyhow, other differential switches can be inserted at the output, possibly coordinated with the switches at the input.

The differential switch located upstream must have the following features:

 differential current adjusted to the sum of the UPS + load. we strongly recommend maintaining an adequate margin to avoid delayed actuation (300mA minimum current)

 type B

 delay greater than or equal to 0,1s

O

UTPUT LINE FUSES

/

THERMAL MAGNETIC SWITCHES

REFER TO THE INCLUDED “INSTALLATION INSTRUCTIONS”

R.E.P.O.

This isolated input can be used to remotely switch off the UPS in case of emergency.

The UPS is supplied by default with "Remote Emergency Power Off" (R.E.P.O.) terminals short-circuited by a jumper (see "User

interface"). To manage emergency shutdown, replace the jumper with the selected normally closed stop device contact.

Connect using double insulation wiring.

In case of an emergency, the stop device opens the R.E.P.O. control and the UPS goes into stand-by mode (all power stages off) and the load is completely disconnected.

The REPO circuit is self-powered with a SELV circuit. No external power supply voltage is therefore required. When closed

(normal condition) it carries a current of max. 15mA.

A

UXILIARY CONTACTS

Terminals for connecting auxiliary contacts of the remote maintenance and remote output bypass switches are available at the back of the UPS (see "Auxiliary contacts section"). These are identified, respectively, by the words “SERVICE BYPASS” and

“AUX SWOUT”.

For installation, refer to the paragraphs “Auxiliary contacts section” and “Remote maintenance bypass”.

SERVICE BYPASS

 Before connecting, remove the pre-assembled jumper

 When the remote maintenance bypass switch is closed, the relative auxiliary contact should open

AUX SWOUT

 When the remote output switch is closed, the relative auxiliary contact should open

Use a double insulation cable with 1 mm2 section for terminal connection

CAUTION: in the case of parallel systems, each single UPS must have its own independent external auxiliary contact

S

CHUKO SOCKET

The UPS is equipped with a schuko socket (see “User interface” view) connected directly to its output.

Safety information: when the UPS is on, if the output switch (SWOUT) is opened, the schuko socket remains live. If the manual bypass switch is engaged (SWMB), the output switch (SWOUT) is opened and the UPS is switched off; in this case the socket is no longer live.

O

PTIONAL ACCESSORIES

E

XTERNAL

S

YNC

This non-isolated input is used to synchronize the inverter output with a suitable signal coming from an external source. It is located on the rear of the UPS (see “Auxiliary contacts section”).

To install:

 use an isolating transformer with single-phase isolated output (SELV) in the range 12-24VAC rated



0.5VA

 connect the transformer secondary to terminals 1-

2 “EXTERNAL SYNC" (see "Auxiliary contacts section" ) with a double insulation cable with 1 mm2 section. Caution: respect polarisation as indicated in the following image. Pole 1 of the terminal is marked with a label.

After installation, enable this option by means of the configuration software.

E

XTERNAL TEMPERATURE SENSOR

This NON-ISOLATED input is used to detect temperature inside a remote Battery Box.

Use ONLY the kit provided by the manufacturer: use which does not observe the specifications may cause the equipment to malfunction or fail.

For installation, connect the cable contained in the special kit to the "EXT BATT TEMP" connector (see "Auxiliary contacts section") following the instructions contained in the relative manual.

After installation, enable this external temperature measuring function by means of the configuration software.

R

EMOTE PANEL

The remote panel allows you to monitor the UPS from a distance and thus have a detailed, real-time overview of machine status. Using this type of device, network, output, battery measurements etc. can be viewed and any alarms detected.

For details related to use and connections, refer to the appropriate manual.

S

ECOND BATTERY CHARGER

The standard version of the UPS has only one battery charger board, with a maximum charging current of 25A. However, the charging current can be increased to 50A with a second board. A kit is available for the second board.

R

EMOTE MAINTENANCE BYPASS

Caution

: carefully read the “Manual bypass (SWMB)” paragraph

A maintenance bypass (manual bypass) can be installed additionally on a peripheral electrical board (see following diagram).

This allows, for example, UPS replacement without interrupting power to the load.

The "SERVICE BYPASS" terminal (see "Auxiliary contacts section") must be connected to the auxiliary contact of the REMOTE MAINTENANCE BYPASS SWITCH (3). When this switch closes, an auxiliary contact signalling insertion of the remote bypass to the UPS must open. Failure to perform this connection can cause power cut-off to the load and UPS damage.



Use switches and power cables suitable for UPS currents.



Use a double insulation cable with a 1mm2 section for connecting "SERVICE BYPASS" and "AUX SWOUT" terminals to relative REMOTE MAINTENANCE BYPASS (3) and OUTPUT (2) switch auxiliary contacts.



Verify compatibility between the "Remote maintenance bypass" and neutral connectivity of the system.

P

ARALLEL CONNECTION

UPS's can be connected in parallel to increase the reliability of power supply to the load (redundancy) and their power delivery.

Up to 8 units can be connected in parallel. Only units of the same power can be connected together in this way.

For example, the figure shows a parallel connection of two UPS's.

When UPS's are connected in parallel, the ECO (LINE INTERACTIVE), SMART (SMART ACTIVE) and STBYOFF (STAND-BY

OFF) modes are not available.

The optional parallel connection kit is required to connect multiple UPS's in this way.

For further information, see the parallel connection manual.

USE

D

ESCRIPTION

The purpose of the UPS is to ensure perfect supply voltage to the equipment connected to it, both in the presence and absence of mains power. Once connected and powered, the UPS generates alternating sinusoidal voltage with stable range and frequency, regardless of sudden changes and/or variations on the mains power. As long as the UPS draws power from the mains, the batteries are kept charged under the control of a multiprocessor board. This board constantly monitors mains voltage range and frequency and the range and frequency of voltage generated by the inverter, applied load, internal temperature and battery efficiency conditions.

The following is a block diagram of the UPS which describes the individual components that it is composed of.

UPS block diagram

IMPORTANT: Our UPS have been designed and built for long-term duration even in the most demanding operating conditions.

Please remember however that these are electrical power devices and, as such, they require periodic inspections. In addition, some components inevitably have their own life cycles and, therefore, they must be checked periodically and replaced if necessary: this is particularly true of the batteries, fans and in some cases, the electrolytic capacitors.

It is therefore recommended to implement a preventive maintenance programme, to be entrusted to manufacturer authorised, qualified personnel.

Our Technical Assistance is at your service to propose different preventive maintenance options tailored to your specific needs.

O

PERATING MODE

The mode that ensures the most load protection is the ON LINE mode, where power for the load undergoes a double conversion and is reconstructed at output in a perfectly sinusoidal way, with frequency and voltage fixed by the precise digital control of the DSP independently from the input (V.F.I.). *

It is possible to select the following modes next to the traditional double conversion ON LINE operating mode:

 ECO (LINE INTERACTIVE)

 SMART (SMART ACTIVE)

 STBYOFF (STAND-BY OFF)

In order to optimise performance, the load is normally powered by the bypass in ECO mode (any disturbances presented on the mains can have repercussions on the load). In the case of no mains or simply output from expected tolerances, the UPS will transfer to normal double conversation ON LINE operation. Approximately five minutes after mains power returns within tolerance, the load is switched back to bypass.

In the event that the user is not able to decide which operating mode is best for use (between ON LINE and ECO), he can entrust the choice to SMART ACTIVE mode.Based on statistics detected regarding power mains quality, the UPS decides on its own which mode to configure.

Finally, in STAND-BY OFF mode, operation is configured as back-up: in the presence of mains, the load is not powered, during a black-out, the load is powered by an inverter by means of batteries, to then be switched off again upon mains return. Intervention time is less than 0.5 sec.

*

The RMS output voltage is determined by the DSP independently of the input voltage, while the frequency of the output voltage is synchronized (within a tolerance to be set by the user) with that of the input for bypass use. Outside of this tolerance, the UPS desynchronizes, bringing itself to the nominal frequency and bypass can no longer be used (free running mode).

CAUTION: When UPS's are connected in parallel, the ECO (LINE INTERACTIVE), SMART (SMART ACTIVE) and STBYOFF (STAND-BY OFF) modes are not available.

M

ANUAL BYPASS

(SWMB)

CAUTION: Contact a service centre should any malfunctions be detected.

UPS maintenance can only be performed by skilled personnel who have been trained by the manufacturer.

CAUTION: dangerous voltages can be present inside the device, even if the input, bypass, output and battery switches are open.

Removal of the UPS's panels by unqualified personnel is dangerous and can cause harm to the operator, equipment and utilities connected to it.

Operations to be performed in order for setting the UPS in "Manual bypass" status without interrupting power to the load:

 Caution: if the UPS is in battery operation, manual bypass insertion may cut off power to the load.

Close the manual bypass switch SWMB behind the door: this connects the input directly to the output.

 Open the SWIN input, SWBYP bypass and SWOUT output switches. Open the external UPS battery line switch/fuses.

The control panel will switch off after a few seconds.

In this operating mode, any disturbance or blackouts on the UPS power line will have repercussions on the powered equipment (the UPS is no longer active and the load is connected directly to the mains).

Operations to be performed to start up the UPS in "Manual bypass" status without cutting off power to the load:(to be performed only when no faults or malfunctions have been detected):

 Close the SWIN input, SWBYP bypass and SWOUT output and the external UPS battery line switches. The control panel will reactivate. Restart the UPS from the "SYSTEM ON" menu. Wait for the sequence to be completed.

 Open the manual bypass switch SWMB: the UPS will resume normal operation.

R

EDUNDANT AUXILIARY POWER ADAPTER FOR AUTOMATIC BYPASS

The UPS is equipped with a redundant auxiliary power supply which permits operation on the automatic bypass even in the event of main auxiliary power faults. In the event of a UPS fault, which also can cause breakage of the main auxiliary power, the load remains powered by means of the automatic bypass.

If the principal power fails, the redundant power supply will continue to power the logic, display and any comms cards.

CAUTION:

In this mode, the backlight and standard RS232 and USB ports will not operate.

The UPS can however communicate via its comms slots.

In this emergency condition, any disturbances present on the input line have repercussions on the load.

P

OWER WALK

-

IN

The UPS is equipped with a Power Walk-In mode which can be activated and configured via configuration software. When this mode is enabled, once the mains power is restored (after a period of autonomy), the UPS begins absorbing from it again progressively so as not to threaten (due to the peak) for any generator group that may be installed upstream. The duration of the transition can be set from 0 to 125 seconds. The default value is 10 seconds (when this function is active). During the transition, the power required is drawn partly from the batteries and partly from the mains while maintaining sinusoidal absorption. The battery charger is switched back on only after the transition is complete

)

UPS status and faults are signalled via a buzzer which emits a modulated sound depending on different UPS operating conditions.

The different types of sounds are described below:

Sound A: This signal is emitted when the UPS is switched on or off using the appropriate buttons. A single beep confirms ON, battery test activation, the cancellation of programmed shutdown.

Sound B: This signal is emitted when the UPS switches to bypass to compensate for current surges due to the insertion of a distorted current.

Sound C: This signal is emitted when the UPS switches to battery operation before No Battery is signalled (sound D). It is possible to silence signals (see "Graphic display" paragraph).

Sound D: This signal is emitted when battery operation reaches No Battery alarm threshold. It is possible to silence signals

(see "Graphic display" paragraph).

Sound E: This signal is emitted when an alarm or lock is detected.

Sound F: This signal is emitted when a battery overvoltage fault is detected.

Sound G: This type of signal is emitted when the battery test fails. The buzzer beeps ten times. This alarm signal is emitted while the "replace batteries" LED is on.

 STATUS: indicates the current UPS status.

// = Parallel Lock

 LOCK: Indicates inhibition of the UPS or a component. A lock is normally preceded by an alarm. In the event of a fault and consequential inverter lock, the inverter will switch off and power to the load via the bypass line (this procedure is excluded for locks caused by serious and persistent overloads and for those caused by a short circuit).
