OVERVIEW
MULTI SENTRY
The UPSs in the MST series have been designed using state-of-the-art technology, in order to ensure the best performance for
the user. The use of the new control boards based on microprocessor architecture (DSP + µP inside), together with the adoption
of specific circuit solutions that use last-generation components, have allowed to reach high performances such as:
ZERO IMPACT SOURCE: ensures low input distortion, a power factor close to 1, and maximum generator set
compatibility.
BATTERY CARE SYSTEM: allows a customised management for different battery types and their continuous
monitoring, therefore enhancing battery efficiency and durability.
SMART INVERTER: guarantees an extraordinary efficiency even at a low-load percentage. Moreover, it ensures a
stable low-distortion output tension even in extreme operating conditions.
Thanks to these and other features, and thanks to its ease of use, the MST series presents itself as a reference point among
three-phase UPSs.

SEPARATE BYPASS INPUT (OPTIONAL)
THE OPTIONAL DI VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES.
The UPS series with Separate Bypass allows a separate connection between the input and the bypass lines.
The UPS output is synchronised with the bypass line, in order to avoid incorrect voltage changeovers during the alternate
phases, in case an automatic bypass or a maintenance isolator closure occurs.
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.
INSTALLATION
ALL OPERATIONS DESCRIBED IN THIS SECTION MUST BE CARRIED OUT BY QUALIFIED PERSONNEL
ONLY.
The company assumes no responsibility for any damage caused by flawed connections or by operations
that are not described in this manual.

(2) The following formula can be used to calculate the air flow rate: Q [mc/h] = 3,1 x Pdiss [kcal/h] / (ta - te) [°C]
Pdiss is the power expressed in kcal/h dissipated by all the devices installed in the installation environment.
ta= ambient temperature, te=external temperature. In order to take leaks into account, it is necessary to increase
the value obtained by 10%.
The table shows an example of a flow rate with (ta - te) =5°C and a rated resistive load (pf=0.9).
(Note: This formula is applicable only if ta>te. If not, the UPS installation requires an air-conditioning system).
(3) The dispersion current of the load is added to that of the UPS on earth wire.
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
As for the installation area of the UPS, and, if necessary, of the Battery Box, follow carefully the following instructions:
Avoid dusty environments
Make sure that the floor is level and that it is able to withstand the weight of the UPS (and of the Battery Box)
Avoid environments which are too narrow, as they could impede normal maintenance operations
The relative humidity should not exceed 90% with no condensation
Make sure that the ambient temperature remains between 0 and 40°C while the UPS is operating
This UPS can operate with an ambient temperature between 0 and 40°C. The recommended working
temperature for the UPS and the batteries is between 20 and 25°C. In fact, with a working temperature of
20°C, a battery has an average operating life of 5 years, whilst with a working temperature of 30°C the
operating life is halved.
Avoid positioning the UPS in places exposed to direct sunlight or hot air
To maintain the temperature in the installation area within the above mentioned range, there must be a system to dispose of the
dissipated heat (the kW / kcal/h / B.T.U./h values dissipated by the UPS are shown in the table in the previous page). The
methods that can be used are the following:
Natural ventilation
Forced ventilation, recommended when the external temperature is lower (e.g. 20°C) than the temperature at which the
UPS or the Battery Box has to be operated (e.g. 25°C)
Air-conditioning system, recommended when the external temperature is higher (e.g. 30°C) than the temperature at
which the UPS or the Battery Box has to be operated (e.g. 25°C)
INTERNAL BATTERIES
CAUTION: If the UPS has INTERNAL BATTERIES, follow all the PRECAUTIONS AND SAFETY RULES listed
below.
•
The UPS has HAZARDOUS electrical voltages inside it, even when the input and/or battery switches are off. The
inside of the UPS is protected by safety panels which should not be removed by untrained personnel. All installation
and maintenance or operations involving access inside the UPS require the use of tools and may ONLY be performed
by trained personnel.
•
The UPS contains an internal source of energy: batteries. All terminals and sockets may be live even without
connecting the UPS to the mains.
•
The total battery voltage may be potentially dangerous: it may generate an electric shock. The battery compartment is
protected by safety panels which should not be removed by untrained personnel. All installation and maintenance of
the batteries involve access inside the UPS and require the use of tools: such operations may ONLY be performed by
trained personnel.
•
Replaced batteries must be considered TOXIC WASTE and treated accordingly. Do not dispose of batteries in a fire:
they may explode. Do not attempt to open the batteries: they are maintenance-free. In addition, the electrolyte is
harmful to the skin and eyes and can be toxic.
•
Do not turn on the UPS if it is leaking fluid or if you see a residual white powder.
•
Do not allow water, liquids in general and/or other foreign objects to get inside the UPS.
•
Do not open the battery fuse holder while the UPS is powering the load in battery operation mode. The interruption of
the battery DC may cause an electrical arc resulting in broken equipment and/or fire. In addition, if there is no mains
power, the energy to power the load is provided by the batteries, therefore opening the battery caps would lead to the
shutdown of the load.
•
Follow these recommendations when working on the batteries:
•
Remove wristwatches, rings and other metal objects
Use tools with insulated handles
Wear rubber shoes and gloves
Do not lay tools or metal objects on top of the batteries
Disconnect the charging source before connecting or disconnecting the battery terminals
Check whether the battery has been inadvertently earthed. If this is the case, disconnect the source from
earth. Contact with any part of the earthed battery may cause an electric shock. The likelihood can be
reduced if the earthing connections are interrupted during installation and maintenance (applicable to remote
battery-powering and equipment, without earthing circuits).
Risk of explosion if the battery is replaced by another of the incorrect type. Refer to the following table to identify the
correct quantities and models:

battery kit installation manual.
REMOVING THE UPS FROM THE PALLET
CAUTION! TO AVOID HARMING PEOPLE AND/OR DAMAGING THE EQUIPMENT, FOLLOW
CAREFULLY THE FOLLOWING INSTRUCTIONS.
SOME OF THESE INSTRUCTIONS NEED TO BE CARRIED OUT BY TWO PEOPLE.
Cut the straps and remove the cardboard box by
sliding it upwards. Remove the packaging material.
Remove the accessory box.
NOTE: the accessory box can be either inside the
packaging, or behind the USP door.
Remove the 2 brackets securing the UPS to the pallet by
unscrewing the screws marked A and B in the figure.
The previously removed brackets can also be used as slides. Secure the slides to the pallet by using the type A screws,
making sure they are aligned with the wheels.
Screw the brake rod completely, so to separate it from the pallet
Make sure that the door is firmly closed.
CAUTION! Push the UPS from the rear with great care. Given the weight of the equipment, this operation needs to
be carried out by two people.
NOTE : It is recommended to keep all parts of the packaging for further use
PRELIMINARY CONTENT CHECK
After opening the package, first check the content:
metal chutes, warranty card, user manual, safety manual, inspection certificate, serial connection cable, 4 x battery fuses (to be
inserted in the “SWBATT” fuse holders), door key.
POSITIONING THE UPS
When positioning the equipment, the following points should be taken into account:
The wheels are intended for accurate positioning, therefore for small movements only.
The plastic parts and the door are not suitable for pushing or gripping the UPS.
Sufficient space should be left in front of the equipment, for it to be switched on and off and in order to allow carrying
out maintenance operations on it ( ≥ 1,5 metres).
The rear part of the UPS should be placed at least at 30 cm from the wall, to allow the air blown by the ventilation fans
to outflow correctly.
No objects should be placed on its upper surface.
Once the equipment has been positioned, secure it with the apposite brake rod (see "Front views of the UPS ").
In earthquake-prone zones or in mobile systems it is possible to use the brackets securing the UPS to the pallet to anchor the
machine to the ground (see figure below). In normal conditions the brackets are not necessary.
OPERATIONS TO ACCESS THE TERMINALS OF THE UPS
To carry out the following operations, the UPS must be disconnected from the mains power supply,
switched off, and with all the equipment switches and fuse holders open.
Follow the instructions provided below to open the UPS:
Open the door using, if necessary, the key provided
Remove the terminal cover in correspondence with the switches (see "Front views of the UPS" )
Once the installation operations inside the equipment have been completed, replace the terminal cover and close the door.
ELECTRICAL CONNECTIONS
WARNING: a 4-wire three-phase distribution system is required.
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.

When the separate bypass option is present, protective devices should be placed 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, therefore they must refer to the
same potential. In case the two power supplies were different, an isolation transformer would be necessary on one of the
inputs.

The maximum input current refers to a nominal load (PF = 0,9), to a 346V+ input voltage, and battery charger under a 7A
charge.
SHORT CIRCUIT
If a fault occurs on the load, the UPS protects itself by limiting the value and the duration of the current supplied (short circuit
current). These values also depend on the UPS operating status at the time of the fault, which can be either:
2
2
UPS in NORMAL OPERATION: the load is instantly commutated to the bypass line (UPS 30kVA I t=20000A s; UPS
2
2
40kVA I t=25000A s): the input line is connected to the output with no internal protection (locked after t>0.5s)
UPS in BATTERY OPERATION: the UPS protects itself by supplying an output current which is about 1.5 the nominal
current for 0.5s, after which it shuts down.
BACKFEED
This UPS is also equipped with an internal protection against backfeed through metal separation devices.
An optional output on the relay board is available for activating a release device to be installed upstream from the UPS.
This UPS has an internal device (redundant bypass power supply) which, in case a fault occurs, activates the bypass
automatically, thus maintaining the load powered with no internal protection and with no limit on the power supplied
to the load.
Under such emergency conditions, any disturbance on the input line will affect the load.
Please see the paragraph “Redundant auxiliary power supply for automatic bypass”, in the “USE” section.
EXTERNAL PROTECTION DEVICES
CIRCUIT BREAKER
When setting up the power supply line, install a circuit breaker with trip curve C (or D depending on the type of load) upstream
from the UPS, as indicated in the following table:

* In the case of a non-linear load, oversize the neutral line N correctly after site assessment.
If the protection device upstream of the UPS interrupts the neutral conductor, it must also interrupt all the phase
conductors at the same time (quadripolar switch).

DIFFERENTIAL
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
WARNING: make sure that the equipment is connected correctly to the input neutral, or else
damages to the UPS may be caused.
The neutral regime is modified only in presence of an isolation transformer or when the UPS operates with a neutral
isolated upstream.
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. It is strongly recommended to keep an adequate margin in
order to avoid delayed interventions (100mA min. - 300mA recommended)
type B or type A
delay greater than or equal to 0,1s
CROSS SECTION OF THE CABLES
We recommend that the INPUT/OUTPUT and the BATTERY cables pass under the UPS.

•
35 mm2 per rigid cables
CONNECTIONS
As for UPSs with separate bypass, please see the subsequent paragraph.
The very first connection to be carried out is that of the protection conductor (earth cable), which must be
connected to the terminal marked PE. The UPS must not operate without being connected to an earthing
system
THE INPUT NEUTRAL MUST ALWAYS BE CONNECTED
DO NOT CONNECT THE OUTPUT NEUTRAL TO THE INPUT NEUTRAL
Connect the input and output cables to the terminal board as shown in the figure below:
Note 1: The protection conductor (earth cable) connection must be carried out through eyelet terminal stud M6
Note 2: Connections to the BATTERY module are required only when the Battery Box is present
(see paragraph "Connecting the UPS to the Battery Box (optional)")
CONNECTIONS OF THE MODEL WITH SEPARATE BYPASS
The very first connection to be carried out is that of the protection conductor (earth cable), which must
be connected to the terminal marked PE. The UPS must not operate without being connected to an
earthing system
THE INPUT AND THE BYPASS NEUTRALS MUST ALWAYS BE CONNECTED.
THE INPUT AND BYPASS LINES MUST REFER TO THE SAME NEUTRAL POTENTIAL.
DO NOT CONNECT THE OUTPUT NEUTRAL TO THE INPUT OR BYPASS NEUTRAL.
Connect the input and output cables to the terminal board as shown in the figure below:
Note 1: The protection conductor (earth cable) connection must be carried out through eyelet terminal stud M6
Note 2: Connections to the BATTERY module are required only when the optional Battery Box is present
CABLE ROUTING
It is recommended to wire the power cables routing them from the back, under the UPS, to the front of the machine, ensuring
they come up in the terminal area as shown:
The lower part of the structure also has slots that can be used to secure the cables using suitably sized clamps.
N.B.
- Tighten the clamps only after tightening the cables in their power terminals.
- Perform the cables so that when the clamp is tightened, they do not strain the power terminals.
R.E.P.O.
This isolated input is used to turn off the UPS remotely in case of emergency.
This UPS is provided from the factory with “Remote Emergency Power Off” (R.E.P.O.) terminals short-circuited (see "Views of
the UPS connections"). If it is to be installed, remove the short-circuit and connect to the normally closed contact of the
stopping device by using a cable that ensures a double isolation connection.
In case of emergency, the R.E.P.O.control is opened by activating the stopping device; 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. Therefore, no external power supply voltage is required. When
closed (normal condition) a maximum current is present.
EXTERNAL SYNC
This non-isolated input can be used to synchronise the inverter output with an opportune signal coming from an external source.
If it is to be installed it is necessary to:
Use an isolation transformer with an isolated single-phase output (SELV) within the range 12÷24Vac with a power ≥
0.5VA
Connect the transformer secondary to the "EXTERNAL SYNC" terminal (see "Views of the UPS connections”) using a
double isolation cable with a 1mm2 cross section. Warning: always respect the polarisation as in the figure below:
After installation, enable the control using the configuration software.
REMOTE MAINTENANCE BYPASS CONNECTION
An additional maintenance bypass may be installed on a peripheral switchboard (see diagram below), for example, o allow
replacing the UPS without interrupting the power supply to the load.
Note: The Company provides this accessory already pre-assembled in an IP65 plastic box.
It is essential to connect the "SERVICE BYPASS" terminal (see "Views of the UPS connections") to the
auxiliary contact of the SERVICE BYPASS switch. The closure of the SERVICE BYPASS switch will open this
auxiliary contact which informs the UPS that the maintenance bypass has been inserted. The absence of this
connection may interrupt the power supply to the load and damage the UPS.
-
Use cables with cross sections in compliance with the indications given in the "Cross section of the cables" paragraph.
-
In order to connect the "SERVICE BYPASS" terminal to the auxiliary contact of the remote maintenance bypass isolator, use
1mm2 double isolation cables.
-
If the UPS is connected to an isolation transformer, check the compatibility between the “remote maintenance bypass” and
the neutral regime of the installation.

CONNECTING THE UPS TO THE BATTERY BOX (OPTIONAL)
THE CONNECTION BETWEEN THE UPS AND THE BATTERY BOX MUST BE MADE WITH THE DEVICES
SWITCHED OFF AND UNPLUGGED FROM THE MAINS
UPS SHUTDOWN PROCEDURE:
Turn off all the devices connected to the USP, or use (if installed) the remote bypass option.
Turn off the UPS following the correct procedure (see “Switching off the UPS”, in the “USE” section).
Open all isolators and fuse holders in the UPS.
Isolate the UPS completely from the mains power supply, by opening all the external protection devices located on the
input and output lines.
Wait a few minutes before working on the UPS.
Remove the UPS terminal cover (see “Operations to access the terminals of the UPS").
CONNECTING THE BATTERY BOX:
Make sure that the battery voltage of the Battery Box corresponds to that allowed by the UPS (check the data plate on
the Battery Box and the UPS manual)
IMPORTANT: make sure that SWBATT fuse holders of the UPS and Battery Box are open.
Before making any connection read carefully the instructions in the Battery Box manual.
Connect the cables coming from the Battery Box to the UPS terminal board (see figure below), making sure to respect
the polarisation. The first connection to be made is that of the yellow-green protection cable.
Once all these operations have been carried out, replace the previously removed terminal covers on the UPS and on
the Battery Box
CHECKING INSTALLATION:
Insert the fuses in the SWBATT fuse holders of the Battery Box.
Close the SWBATT fuse holders of the Battery Box and the UPS.
Carry out the UPS start-up procedure indicated in this manual.
After about 30 seconds, check that the UPS is operating correctly: simulate a black-out by opening the SWIN input
isolator of the UPS. The load should continue to be powered, and the “battery power” LED should light up on the UPS
control panel. The latter should beep at regular intervals. Once the SWIN input isolator has been closed again, the
UPS should resume operating on mains power.
SETTING THE NOMINAL BATTERY CAPACITY – SOFTWARE CONFIGURATION
Once the BATTERY BOX has been installed, it is necessary to configure the UPS to update the nominal capacity value (total Ah
of batteries inside the UPS + external batteries).
To perform this operation, use the dedicated configuration software.
EXTERNAL TEMPERATURE PROBE
This NON-ISOLATED input can be used to measure the temperature inside a remote Battery Box.
It is essential that only the kit provided by the manufacturer is used. Any uses not conforming to the specifications
may cause faults or breakdowns of the equipment.
As for installation, connect the cable included in the special kit (optional) to the "EXT T_BATT" connector (see "Views of the
UPS connections") following the instructions in the manual.
After installation, enable the outdoor temperature measuring function using the configuration software.
REMOTE SYNOPTIC PANEL (OPTIONAL)
The remote synoptic panel allows remote monitoring of the UPS and therefore, ensures a detailed real-time overview of the
machine status. With this device, it is possible to keep the mains, the output and the battery measurements under control, and
detect any alarm. .
For further information regarding the connection and use of this device, please refer to its apposite manual.
USE
DESCRIPTION
The purpose of this UPS is to ensure a perfect power supply voltage for the devices connected to it, whether mains power is
present, or not. Once it has been connected and powered, the UPS generates a sinusoidal alternating voltage with stable
amplitude and frequency, regardless of any sudden change or variation in the mains supply. While the UPS draws energy from
the mains, the batteries are kept under charge, controlled by the multiprocessor board. This board also monitors 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 battery efficiency.
The UPS block diagram is shown below with a description of its individual components.

IMPORTANT: Our UPSs are designed and built for long durability, even under the most stringent operating conditions.
However, it is important to remember that they are electrical power equipments and therefore, need regular checks. Moreover,
some components inevitably have a life cycle of their own, so, for this reason, they need to be checked regularly and, if
necessary, be replaced. This is referred in particular to the batteries, the fans and, in some cases, to the electrolytic
condensers.
Therefore, a preventive maintenance programme is strongly recommended. This preventive maintenance programme must be
entrusted to specialised personnel authorised by the manufacturer.
Our Technical Servicing department is at your disposal for customised preventive maintenance options.
PRELIMINARY OPERATIONS AND FIRST START-UP
Visual check of the connection
Make sure that all the connections have been made by following carefully the instructions given in the "Connections"
paragraph.
Check that all the isolators are open.
Closure of the battery fuse holders
Close the 4 battery fuse holders (SWBATT) as shown in the figure below.
WARNING: if an external Battery Box is present and the connection does not comply with the instructions
given in "Connecting the UPS to the Battery Box (optional)" paragraph, the battery fuses and other
protections may result damaged. In that case, please contact the Customer Service department, in order to
prevent further damages to the UPS.
When the fuses are closed, a small arc may occur due to charge of the condensers inside the UPS. This is
normal, and does not cause faults and/or damages.
UPS powering
Close the protections upstream the UPS.
Closure of the input and output isolators
Close the SWIN and SWBYP (if present) input isolators. Close the SWOUT output isolator but leave the SWMB
maintenance isolator open.
After a few seconds, check that the display is turned on and that the UPS
enters STAND-BY mode.
If an error message appears on display indicating a wrong cyclic sense of the input phases, perform the following
operations:
Open all the input and output isolators
Wait for the display to turn off
Open the battery fuse holders
Open all the protections upstream the UPS
Remove the protective panel covering the input terminal board
Correct the position of the input wires so that the cyclic sense of the phases is respected.
Only if the separate bypass option is present: check which terminal board (input and/or bypass) the code error shown
on display corresponds to (see the “Alarm codes” paragraph); correct the position of the wires following the indications
on the terminal board.
Close the protective panel again
Repeat the preliminary operations given in the previous page.

battery fuse holders.
GRAPHIC DISPLAY
Located at the centre of the control panel there is a large graphic display, which provides, in the foreground and in real-time, a
detailed overview of the UPS status. The user can switch on and off the UPS, consult the electrical measurements of the mains,
(1)
output, battery etc. , and make the main machine settings directly from the control panel.
The display is divided into four main areas, each with its own specific function.

MENU DISPLAY
OPERATING MODE
The mode that guarantees the maximum protection for the load is the ON LINE mode, in which the Energy for the load
undergoes a double conversion and is reconstructed at the output in a perfectly sinusoidal manner, with the frequency and the
voltage set by a precise digital control of the DSP regardless of the input (V.F.I.). *
In addition to the traditional ON LINE double-conversion mode, it is possible to select the following modes:
ECO (LINE INTERACTIVE)
SMART (SMART ACTIVE)
STBYOFF (STAND-BY OFF)
In order to optimise the efficiency, in ECO mode the load is normally powered from the bypass (any interference on the mains
can affect the load). In absence of the mains, or when the mains voltage exceeds its tolerance limit, the UPS commutates to the
normal ON LINE double-conversion mode. About five minutes after having returned within its tolerance limits, the load is
commutated back to bypass.
If the user cannot decide which is the most suitable operating mode (between ON LINE and ECO) the choice can be left to the
SMART ACTIVE mode, in which, according to statistical data on the quality of the mains power supply, the UPS autonomously
decides in which mode to configure itself.
Finally, in STAND-BY OFF mode, the UPS is set to operate as a back-up device:
In presence of the mains power, the load is not powered, whilst in the event of a black-out, the load is powered by the inverter
via the batteries. When the mains power is restored, the load is powered off again. The activation time is less than 0.5 seconds.
MAINTENANCE BYPASS (SWMB)
WARNING: Maintenance inside the UPS must be carried out by qualified personnel trained by the
manufacturer only. In fact, inside the equipment there may be a voltage even when the input, output and
battery switches are open. Removal of the UPS panels by non-qualified personnel may cause harm to the
operator and damage to the equipment.
Listed below are the operations to be performed in order to carry out the maintenance on the equipment with no interruption of
the power supply to the load:
With the mains voltage present, the UPS must power the load through the inverter or the automatic bypass.
N.B.: If the UPS is in battery power mode, activating the maintenance bypass may imply an interruption of the power
supply to the load.
Close the maintenance bypass isolator (SWMB) located behind the door. This way, the input is short-circuited with the
output.
Open the input switches (SWIN), the output switches (SWOUT), and the battery fuse holders (SWBATT) located
behind the door. The signal panel is turned off. Wait for the electrolytic condensers on the power board to discharge
(about 20 minutes) and then proceed with the maintenance operations.
N.B.: During this phase, with the load powered via the maintenance bypass, any disturbance on the UPS power supply
line would affect the equipment powered (the load is connected directly to the mains. The UPS is no longer active).
Moreover, the auxiliary "Power share" and "Power out" sockets, are no longer powered (see "Auxiliary (power
share)sockets" in the "USE" section).
Once these maintenance operations have been completed, perform the following operations to restart the UPS:
*
Close the input and output isolators and the battery fuse holders. The signal panel is reactivated. Turn the UPS on
again from the “SYSTEM ON” menu. Wait for the sequence to be completed.
Open the maintenance bypass: The UPS resumes normal operation.
The rms value of the output voltage is set by the precise control of the DSP, regardless of the input voltage, while the output voltage
frequency is synchronised (within a tolerance range which can be set by the user) with the input voltage, in order to allow use of the bypass.
Outside this tolerance range, the UPS desynchronises adopting the nominal frequency and the bypass can no longer be used (free running
mode).
REDUNDANT AUXILIARY POWER SUPPLY FOR AUTOMATIC BYPASS
This UPS is provided with a redundant auxiliary power supply which allows the UPS to run on an automatic bypass, even in the
event of faults on the main auxiliary power supply. If a fault occurs in the UPS, shutting off the main auxiliary power supply, the
load will be powered anyway by the automatic bypass. The multiprocessor board and the control panel are not powered;
therefore the LEDs and the display are off.
AUXILIARY “POWER SHARE” AND “POWER OUT” SOCKETS (OPTIONALS)
The "Power share" socket is a programmable output socket which enables, under certain operating circumstances, the
automatic disconnection of the load applied to it. The events that determine this automatic disconnection of the “power share”
socket can be selected by the user through the configuration software (see "Configuration software” and “Configuring the UPS"
paragraphs). For example, the disconnection could be selected after a given time of battery operation, or when the end-ofbattery-charging pre-alarm threshold is reached, or when an overload occurs.
The "Power out" socket is connected directly to the UPS output and it is useful to power accessories such as modems, for
example
.
Safety notes: when the UPS is switched on, if the output isolator (SWOUT) is opened, the sockets will remain
powered.
If the manual bypass isolator (SWMB) is inserted, the output isolator (SWOUT) is opened and once the UPS is
turned off, the sockets are no longer powered.
POWER WALK-IN
This UPS is equipped in series with a Power Walk-In mode, which can be activated and configured through the configuration
software. When the mode is active, and mains power is restored (after an autonomy period) the UPS resumes absorbing
progressively from it, in order to prevent stress (due to the peak) on any generator set installed upstream. The transient time
can be set from 1 to 125 seconds. The default value is 10 seconds. During the transient, the necessary power is drawn partially
from the batteries and partially from the mains, maintaining a sinusoidal absorption. Once the transient is over, the battery
charger is turned on again.
POWER REDUCTION FOR 200/208V PHASE-NEUTRAL LOADS
In case the output voltage is set to 200V or 208V PHASE-NEUTRAL (see the “Configuring the UPS” paragraph), the maximum
power output of the UPS is reduced compared to its nominal value, as shown in the diagram below:
CONFIGURING THE UPS

BUZZER
The status and the faults of the UPS are signalled by the buzzer, which will emit a sound according to the various operating
conditions of the UPS.
The various kinds of sounds are described below:
Sound A:
This signal is emitted when the UPS is turned on or off using the apposite buttons. A single beep confirms the startup, the activation of the battery test, and the cancellation of the programmed switch-off. By keeping the power-off
button pressed, the buzzer will emit in rapid succession sound A four times, before confirming the switch-off with a
fifth beep.
Sound B:
This signal is made when the UPS commutates to bypass in order to compensate the surge current due to the
insertion of a distorting load.
Sound C:
This signal is emitted when the UPS switches to battery operation, before the low battery signal (sound D). It is
possible to silence the signal (see the “Graphic display” paragraph).
Sound D:
This signal is made during battery operation, when the low battery threshold is reached. It is possible to silence the
signal (see the “Graphic display” paragraph).
Sound E:
This signal is emitted in the presence of an alarm or lock.
Sound F:
This signal is emitted if a battery overvoltage fault occurs
Sound G:
This signal is made when the battery test fails. The buzzer beeps ten times. The alarm signal is maintained with the
“replace batteries” LEDs on.

Locks: these codes indicate that the UPS, or one of its parts, is locked. Usually, they are preceded by an alarm signal.
In case of faults and consequent locking of the inverter, the latter will be turned off and the load will be powered via the
bypass line (this procedure is excluded for locks caused by serious and persistent overloads and for those caused by a
short circuit).
