TECHNICAL DATA
45 49 53 OVERVIEW
The new three-phase/single-phase UPS 10 – 12 – 15 – 20 kVA series (VFI-SS-111 type) have been designed using the latest
technology available today so as to guarantee users maximum performance. The use of the new control PCBs based on
multiprocessor architecture (DSP + μP inside) together with high frequency IGBT technology offers excellent performance both
in the input stage (absorbed current harmonic distortion ≤ 3%) and in output (output voltage distortion ≤ 1%).
Thanks to these and many other features plus the easy-to-use design, this new series represents a new reference standard for
single-phase output UPS systems.
Depending on user requirements, there are two different versions available:
Standard
Long Autonomy
The Standard version stands out by its compact size
and new, modern design. These features make it
suitable for any environment.
The Long Autonomy version, offers longer autonomy
than the Standard version, thanks to the possibility to
double the number of batteries inside the cabinet.

BATTERY BOX (OPTIONAL)
THE BATTERY BOX IS AN OPTIONAL ACCESSORY. THIS UPS RANGE HAS BATTERY BOX VERSIONS OF THE SAME
SIZE AND MATCHING STYLE.
The Battery Box contains batteries that increase the operating time of the UPS during prolonged black-outs. The number of
batteries contained in it will vary according to the type of UPS to which the Battery Box is to be installed. The utmost attention
must be paid to ensure that the battery voltage of the Battery Box corresponds to that supported by the UPS.
Standard
Long Autonomy
Additional Battery Boxes may be connected in a chain to obtain the desired autonomy time during a power failure.
This series of Battery Box contains two separate strings of batteries, one with a positive voltage and the other with a negative
voltage with respect to the neutral terminal (N).
The basic diagram for the Battery Box is shown here below.

SEPARATE BYPASS INPUT (OPTIONAL)
THE DI (OPTIONAL) VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The UPS series with separate Bypass ensures a separate connection between the input and bypass lines.
The UPS output is synchronised with the bypass line so as to safeguard against incorrect voltage changeovers in the alternate
phases, in the event of automatic bypass or closing of the maintenance switch (SWMB).
INTERNAL TRANSFORMER
THE OT (OPTIONAL) VERSION OF THE UPS SERIES DIFFERS FROM THE STANDARD VERSION IN THAT IT USES AN
ISOLATION TRANSFORMER INSTEAD OF THE BATTERIES.
This series of UPS uses an isolation transformer connected to the UPS output terminals.
NOTE: A separate bypass line is supplied on this UPS version.
The transformer is connected to the UPS output terminals, so the values displayed are those of the quantities
measured upstream of the transformer.
The presence of the transformer inside the UPS modifies the system neutral arrangements.
The installation of a remote maintenance bypass parallel to the UPS is incompatible with inclusion of the transformer.
In any event, if the remote maintenance bypass is inserted, make sure, at the time the remote bypass switch is
closed, that the UPS is isolated from the system by opening the input and/or output switches.
ADDITIONAL INTERNAL BATTERY CHARGERS
THE AC (OPTIONAL) VERSION OF THE UPS SERIES DIFFERS FROM THE STANDARD VERSION IN THAT SOME
ADDITIONAL BATTERY CHARGERS ARE USED INSTEAD OF THE BATTERIES.
This series of UPS must be used together with an external Battery Box and is suitable for applications requiring long back-up
times.
NOTE: A separate bypass line is supplied on this UPS version.
The additional internal battery charger cards are powered directly on mains power and have pseudo-sinusoidal wave form
absorption.
If the input switch is closed but the I/O switch is open (UPS switched off) the battery chargers operate independently.
Open the input switch (SWIN) to totally shutdown the UPS and the additional battery chargers.

** The following formula can be used to calculate the fan capacity: Q [mc/h] = 3.1 x Pdiss [kcal/h] / (ta - te) [°C]
Pdiss is the dissipated power of all the installed apparatus at the installation premises expressed in kcal/h.
ta= environmental temperature, te= external temperature. To account for leaks, increase the value obtained by 10%.
The table shows an example of the fan capacity with (ta - te)=5°C and with nominal resistive load (pf=0.8).
(N.B.: The formula applies if ta>te; otherwise an air conditioner should be installed).
*** The dispersion current of the load is added to the dispersion current of the UPS on the earth protection conductor.
ELECTROMAGNETIC COMPATIBILITY
This UPS product conforms to the current electromagnetic compatibility (EMC) regulations (C2 class). It may cause radio
interference in the home environment. The user may have to adopt supplementary measures.
This product is for professional use in industrial and commercial environments. Connections to USB and RS232 connectors
must be made with the cables provided, or at least with shielded cables less than 3 metres long.
INSTALLATION ENVIRONMENT
When choosing the site in which to install the UPS and the Battery Box, the following points should be taken into consideration:
ƒ
Avoid dusty environments
ƒ
Check that the floor is level and capable of withstanding the weight of the UPS and the Battery Box
ƒ
Avoid cramped environments that could impede the normal maintenance activities
ƒ
The relative humidity should not exceed 90%, non-condensing
ƒ
Check that the ambient temperature, with the UPS running, remains between 0 and 40°C
The UPS may be operated with an ambient temperature of between 0 and 40°C. The recommended
working temperature for the UPS and the batteries is between 20 and 25°C. In fact, if the battery has an
average life of 5 years with a working temperature of 20°C, the life is halved if the working temperature is
increased to 30°C.
ƒ
Avoid installing the equipment in places exposed to the direct sunlight or hot air
To keep the temperature of the installation room within the range indicated above, there must be a system for eliminating the
dissipated heat (the UPS kW / kcal/h / B.T.U./h dissipation values are shown in the table on the previous page). The methods
that may be used are:
ƒ
Natural ventilation
ƒ
Forced ventilation, recommended if the outside temperature is less (e.g. 20°C) than the temperature at which the UPS
or Battery Box is to be operated (e.g. 25°C)
ƒ
Air-conditioning system, recommended if the outside temperature is higher (e.g. 30°C) than the temperature at which
the UPS or Battery Box is to be operated (e.g. 25°C)

INSTALLING THE UPS AND THE BATTERY BOX
When installing the equipment, the following points should be considered:
ƒ
The wheels are to be used exclusively for fine positioning, and thus for small distances only.
ƒ
The plastic parts and the door are not to be used for gripping or pushing the UPS.
ƒ
Sufficient space should be left in front of the equipment for it to be turned on/off and maintenance operations to be
performed on it ( ≥ 1.5 mt )
ƒ
The rear part of the UPS should be set at least 30 cm from the wall, to enable the air blown by the ventilation fans to
flow away correctly
ƒ
No objects should be left on its top surface
Having set the equipment in position, secure it by engaging the brake rod (see "Front Views of the UPS" point 8) situated below
the connecting terminals.
(Long Autonomy version only): In seismic areas or for mobile systems, the brackets used to fasten the unit to the pallet
(ramps) can be reused to anchor the UPS to the floor (see the figure below). In normal conditions, the brackets are not
necessary.
STEPS TO BE TAKEN TO GAIN ACCESS TO THE TERMINALS OF THE UPS / BATTERY BOX
The operations indicated below are to be performed with the UPS disconnected from the mains powers,
turned off and with all the switches and fuse holders of the equipment open.
Follow the instructions provided below to open the UPS:
ƒ
Open the door
ƒ
Remove the terminal and switches cover (see "Views of the UPS" ref. 7)
Having completed the installation operations inside the equipment, replace the terminal cover and close the door.
ELECTRICAL CONNECTIONS
WARNING: a 4-wire three-phase distribution system is required for the three-phase input connection. The
UPS must be connected to a power supply line made up of 3 phases + neutral + PE (protective earth) of TT, TN or IT
type. Therefore, the phase rotation must be respected.
Optional TRANSFORMER BOXES to convert the distribution systems from 3 wires to 4 wires are available.
WIRING DIAGRAMS FOR CONNECTING TO THE ELECTRICAL SYSTEM
NOTE: for the following diagrams, in cases of single-phase connections on the input line, instead of 3P=N, please read P+N.
UPS with no variation of the neutral arrangements
UPS with galvanic isolation on input
Note: For three-phase connections, the transformer must be suitably sized to operate off the bypass
UPS with galvanic isolation on output
UPS without any variation in neutral condition and with separate bypass input
UPS with galvanic isolation and with separate bypass input
UPS with galvanic isolation at output and separate bypass input
Separate bypass:
if the separate bypass option is present, protective devices must be present on both the main power supply line and the bypass
line.
Note: the neutral of the input line and that of the bypass are commoned inside the equipment, so they must refer to the same
potential. If the two power supplies were different, an isolation transformer would have to be used on one of the inputs.

The max. input current refers to a rated load (PF = 0.9) and an input voltage of 346V,
and a battery charger charged with 4A.
** In versions with additional internal battery chargers (optional), the maximum input current on lines L2 and L3 must be
increased by 7A.
SHORT CIRCUIT
If a failure occurs on the load, the UPS protects itself by limiting the value and duration of the current output (short-circuit
current). These values also depend on the operating status of the UPS at the time of the failure; there are two different cases:
ƒ
UPS in NORMAL OPERATION: the load is switched instantaneously to the bypass line (I2t=11250A2s): the input line is
connected to the output without any internal protection (blocked after t>0.5s)
ƒ
UPS in BATTERY OPERATION: the UPS protects itself by providing a current equivalent to about 1.5 times the rated
current for 0.5s and turns itself off after this time has elapsed
BACKFEED
The UPS has internal protection against backfeed through metal separating devices.
There is an output on the relay board (optional) for activating a releasing device to be installed upstream from the UPS.
The UPS has an internal device (redundant bypass power supply) which, when a failure occurs on the machine,
activates the bypass automatically, thus keeping the load powered without any internal protection and without any
limitation to the power supplied to the load.
Under these emergency conditions, any disturbance present on the input line will affect the load.
See also the “USE” section of the “Redundant Auxiliary Power Supply for Automatic Bypass” paragraph.
EXTERNAL PROTECTIVE DEVICES
MAGNETOTHERMAL
As explained previously, the UPS has protection devices for output faults as well as for internal faults.
In order to set up the power line, install a magnetothermal switch upstream from the UPS with intervention curve C. Please
follow the indications in the table below:

DIFFERENTIAL
In versions with no input separation transformer, the neutral from the mains power supply is connected to the UPS output
neutral; as a result, there will be no change to the neutral arrangements of the installation:
THE UPS INPUT NEUTRAL IS CONNECTED TO THE UPS OUTPUT NEUTRAL
THE DISTRIBUTION SYSTEM THAT POWERS THE UPS IS NOT MODIFIED BY THE UPS
The neutral condition is only modified if an isolation transformer is present or when the UPS works with a neutral
isolated upstream.
Make sure that the equipment is connected correctly to the input neutral because as damage may be caused
to the UPS.
During operation with the mains supply present, a differential switch (RCD) at the input to the UPS will activate should a fault
occur on the output side as the output circuit is not isolated from the input circuit.
In any case, other differential switches may still be installed on the output, preferably in coordination with those present at the
input.
The differential switch located upstream must have the following characteristics:
ƒ
Differential current adjusted to the sum of UPS + Load; we recommend a suitable margin be kept to prevent unwanted
activation (100mA min. - 300mA recommended)
ƒ
Type B or type A
ƒ
Delay of at least 0.1s
CROSS SECTION OF THE CABLES

Apply the short circuit to the three input bushings (see "View of UPS connections", ref. 21) using the bar and the three screws
provided in the supplies box as shown in the left hand figure below. Then connect the phase cable to L1 as indicated in the
figure below right.
Note: the connections to the UPS terminals remain unchanged with respect to those indicated in the foregoing paragraphs.
R.E.P.O.
This isolated input is used to turn off the UPS remotely in case of emergency.
The UPS is supplied from the factory with the “Remote Emergency Power Off” (R.E.P.O.) terminals short-circuited (see "View of
UPS connections” ref.15). If it is to be installed, remove the short-circuit and connect to the normally closed contact of the stop
device using a cable that provides a double isolation connection.
In case of emergency, by activating the stop device, the R.E.P.O. control is opened and the UPS enters stand-by mode (see
“USE” section), and powers off the load completely.
The R.E.P.O. circuit is self-powered with SELV type circuits. No external power supply voltage is therefore required. When it is
closed (normal condition), a maximum current of 15mA is present.
EXTERNAL SYNC
This non-isolated input is used to synchronise the inverter output with an appropriate signal coming from an external source.
For the installation:
¾
¾
use an isolation transformer with an isolated single-phase output (SELV) comprised in the range 12-24Vac with ≥
0.5VA power
connect the transformer secondary to the "EXTERNAL SYNC" terminal (see "View of UPS connections” ref.19) using a
double isolation cable with a 1mm2 cross-section. Make sure to respect the polarisation as in the figure below.
After installation, activate the command using the advanced configuration software UPSTools provided on the CD-ROM shipped
with the UPS system.
CONNECTING THE REMOTE MAINTENANCE BYPASS
An additional maintenance bypass may be installed on a peripheral switchboard, for example, to enable the UPS to be replaced
without interrupting the power supply to the load.
It is absolutely essential to connect the "SERVICE BYPASS" terminal (see "View of UPS connections" ref.
17) to the auxiliary contact of the SERVICE BYPASS switch. Closing the SERVICE BYPASS switch (4) opens
this auxiliary contact which informs the UPS that the maintenance bypass has been activated. If this
connection is not present, the power supply to the load may be shut off and the UPS damaged.
NOTES:
Use cables with a cross section that conforms to the indications given in "Cross Section of the Cables ".
Use a double insulated cable with a cross section of 1mm2 to connect the "SERVICE BYPASS" terminal to the
auxiliary contact of the remote maintenance bypass isolator.
Whenever the UPS is equipped with internal isolation transformer, check the compatibility between the
“remote maintenance bypass” and the neutral arrangement in the electrical plant.

alarm conditions.
For further information regarding the connection and use of this device, please refer to its apposite manual.
USE
DESCRIPTION
The purpose of a UPS is to ensure a perfect power supply voltage for the devices connected to it irrespective of whether mains
power is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a stable
amplitude and frequency, irrespective of the changes and/or variations occurring on the electricity network. For as long as the
UPS receives energy from the mains, the batteries are kept charged under the control of the multiprocessor board. This board
also controls continuously the amplitude and frequency of the mains voltage, the amplitude and frequency of the voltage
generated by the inverter, the load applied, the internal temperature and the state of efficiency of the batteries.
The block diagram below shows each of the parts that make up the UPS.
Block diagram of the UPS
IMPORTANT: Our UPS are designed and produced for long life even under the severest conditions. Remember however that
they are electrical power equipment items and as such are in need of periodic checks. Besides, some components have a life
cycle of their own and must therefore be checked at regular intervals and may need to be replaced, where due to the conditions:
in particular, the batteries, fans and in some cases the electrolytic capacitors.
It is recommended to implement a preventive maintenance program, using manufacturer authorised and trained service
personnel.
Our Technical Servicing department is at your disposal to discuss the different personalized preventive maintenance options
with you.

DISPLAY MENUS
OPERATING MODES
The mode that guarantees maximum protection for the load is ON LINE mode, in which the energy for the load is converted
twice and is generated perfectly sinusoidal at the output with the frequency and voltage set by the fine digital control of the DSP
irrespective of the input (V.F.I.). *
In addition to the traditional, double-conversion ON LINE operating mode, the following modes may be selected:
¾
ECO (LINE INTERACTIVE)
¾
SMART (SMART ACTIVE)
¾
STBYOFF (STAND-BY OFF)
In order to optimize efficiency, in ECO mode, the load is normally powered from the bypass. If the mains voltage exceeds the
allowed tolerance limits, the UPS switches to normal, double-conversion ON LINE mode. About five minutes after it has
returned within the tolerance limits, the load is switched back to bypass.
If you are not sure which operating mode (ON LINE or ECO) to choose, the UPS may be set in SMART ACTIVE mode in which,
according to statistical data on the quality of the power supply mains, the UPS autonomously decides the mode it is to enter.
Finally, in STAND-BY OFF mode, the UPS is set to operate only in an emergency:
when the mains power is present, the load is powered off while, in the event of a black-out, the load is powered by the inverter
via the batteries, and is then powered off again when mains power is restored. The activation time is less than 0.5 sec.
MAINTENANCE BYPASS (SWMB)
WARNING: Maintenance work inside the UPS is to be performed exclusively by qualified staff. Inside the
UPS there may be a voltage present even when the input, output and battery switches are open. Removal of
the UPS panels by non-qualified staff may result in injury to the operator and damage the equipment.
Below is a list of the operations to be performed in order to carry out maintenance work on the equipment without shutting off
the power supply to the load:
¾
The UPS must power the load via the automatic bypass or the inverter, with the mains voltage present.
N.B.: If the UPS is in battery power mode, activating the maintenance bypass entails shutting off the power supply to
the load.
¾
Close the maintenance bypass isolator (SWMB) situated behind the door: in this way, the input is short-circuited with
the output.
¾
Open the input switches (SWIN), output switches (SWOUT) and battery fuse holders (SWBATT) situated behind the
door: The signal panel is turned off. Wait for the electrolytic capacitors on the power board to discharge (about 15
minutes) and then proceed to perform the maintenance operations.
N.B.: During this phase, with a load powered via the maintenance bypass, any disturbance on the power supply line of
the UPS will affect the devices powered (The load is connected directly to the mains. The UPS is no longer active).
Having completed the maintenance operations, proceed as follows to restart the UPS:
*
¾
Close the input and output isolators, and the battery fuse holders. The signal panel is reactivated. Turn on the UPS
again from the “SYSTEM ON” menu. Wait for the sequence to be completed.
¾
Open the maintenance bypass: the UPS resumes normal operation.
The rms value of the output voltage is set by the fine control of the DSP irrespective of the input voltage while the frequency of the output
voltage is synchronized (within a tolerance range that may be set by the user) with the input voltage to enable the bypass to be used.
Outside this range, the UPS desynchronizes and returns to the rated frequency and the bypass may no longer be used (free running mode).
REDUNDANT AUXILIARY POWER SUPPLY FOR AUTOMATIC BYPASS
The UPS is equipped with a redundant auxiliary power supply that enables the UPS to run on an automatic bypass even when a
failure occurs in the main auxiliary power supply. If a fault occurs in the UPS shutting off the main auxiliary power supply, the
load is powered by the automatic bypass. The multiprocessor board and the control panel are not powered so the LEDs and the
display are off.
PROGRAMMABLE AUXILIARY SOCKET (POWER SHARE)
The UPS has an output socket that enables the load applied to it to be disconnected automatically under certain operating
conditions. The events that determine the automatic disconnection of the Power share socket may be selected using the
configuration software UPSTools (see the Configuration software and UPS Configuration paragraphs).
For example, the socket can be disconnected after a given time of battery operation, or when the battery low prealarm threshold
is reached or an overload occurs.
Safety notes: when the UPS is switched on, if the output switch (SWOUT) is opened, the Power share socket will
remain connected to the mains.
If the manual bypass switch (SWMB) is inserted, the output switch (SWOUT) is opened and when the UPS is
shutdown, the socket will be disconnected.
POWER WALK-IN
The UPS has a Power Walk-in mode which can be enabled and configured using the software UPS Tools. When the mode is
enabled and mains power is restored after a period of battery operation, the UPS starts to draw progressively from it so as not
to stress (due to the peak) any generating set installed upstream. The transient time may be set from 1 to 30 seconds. The
default value is 10 seconds. During the transient, the necessary power is drawn in part from the batteries and in part from the
mains, maintaining sinusoidal absorption. The battery charger is turned on again once the transient has passed.
REDUCING THE LOAD (TO 200V AND 208V)
If the output voltage is set to 200V and 208V (see “Configuring the UPS” paragraph), the maximum power output of the UPS is
reduced with respect to its rated value, as shown in the graph below:
CONFIGURING THE UPS

The various kinds of sound are described here below:
Sound A:
The signal is emitted when the UPS is turned on or off using the relevant buttons. A single beep confirms power-on,
activation of the battery test, cancellation of the programmed power-off. When the power-off button is kept pressed,
the buzzer emits the sound A quickly four times, before confirming power-off by emitting a fifth beep.
Sound B:
The signal is emitted when the UPS switches to bypass to compensate for the surge current due to the activation of
a distorting load.
Sound C:
The signal is emitted when the UPS switches to battery operation before the battery low signal (sound D).
Possibility of silencing the report (see paragraph “Graphic Display”)
Sound D:
The signal is emitted during battery operation when the battery low alarm threshold is reached.
Possibility of silencing the report (see paragraph “Graphic Display”)
Sound E:
This signal is emitted in the presence of an alarm or lock.
Sound F:
This signal is emitted if the battery overvoltage fault occurs
Sound G:
This type of signal is emitted when the battery test fails. The buzzer emits ten beeps. The alarm signal is
maintained by the “batteries to be replaced” LED lights up.

TROUBLESHOOTING GUIDE
Irregular operation of the UPS is very often not an indication of a fault but is simply caused by simple problems or distractions.
We therefore recommend you consult the table here below, which provides some information that will help you to solve the most
common problems.
WARNING: the table below frequently recommends the use of the maintenance BYPASS. We remind you that
before restoring the UPS to operation, you must make sure that it is on and not in STAND-BY.
If the UPS is in this latter mode, turn on the UPS by accessing the “SYSTEM ON” menu and wait for the power-on
sequence to be completed before removing the maintenance BYPASS.
For further details read the procedures described in the maintenance BYPASS (SWMB) paragraph.
NOTE: For a detailed explanation of the codes listed in the table, see the “STATUS/ALARM CODES” paragraph.
