4. APPLICATIONS
MULTI SENTRY UPS are suitable for applications requiring critical load protection, from simple installation to those
most complex where the request of the reliability and maintainability is most required.
LAN, Server and Datacentre: the 0,9 output power factor ensures greater active power availability for efficient
UPS loading.
e-business and Telecommunications: parallel operation means that the installed UPS size can be increased (up
to 6 units) to keep pace with the growth of the organisation.
Industrial processes and electro-medical systems: the UPS is designed to protect a range of loads, from industrial
processes to electro-medical applications. This has been achieved through careful load analysis at the design
stage of the MULTI SENTRY project, to ensure the following characteristics:
Optimum input technical characteristics with zero impact on the power supply source.
High short circuit and overload capacity.
High battery recharge capacity with the option to use a variety of battery types (sealed valve
regulated and open-vented) for long back-up times.

5. CONFIGURATIONS
The available configurations are the following:
Single UPS
The group on single version, normally used for simple installation, can be expanded until 6 units (4 in 3/1 version),
to satisfy increases of the power load or to introduce the redundant level.
Parallel configuration
Up to 8 UPSs (4 units in the 3/1 version) can be connected in parallel to increase the power of the uninterruptible
power system (power parallel) or to enhance its reliability (redundant parallel).
The system is defined as “redundant parallel” when the stoppage of one or several UPSs does not determine the
loss of the power supply.
All the UPSs power the load simultaneously with automatic sharing of the current.
The units exchange information on the operating status and the sync signals means the connections in loop with
dual redundancy. This means that even in the event of the accidental interruption of both connections, only the
UPS affected by this interruption cuts itself off, while the other one continues to operate without any interference.
Maximum communication cable length between two UPS should not exceed 50 meters keeping in mind that
total length for the overall ring is 100 meters.

MULTI SENTRY

Standard communication cable, part of installation kit is 5 meters long for all Multi Sentry range 10÷200; user may
arrange for a longer cable (according with prescriptions above mentioned) using RJ45 standard cables
available in the market.
Thanks to the “Hot System Expansion” feature means that a new UPS can be added to the system while the other
units are on-line and powering the load from the inverter.
The integrated UPS will configure itself automatically with the system data without any disturbance to the load.
NOTE: for realizing a parallel configuration where is required a transformer connected downstream each single
UPS please contact the manufacturer in advance.

6. UPS DESCRIPTION
The UPS can be operated in four main operating modes: ON-LINE, FREQUENCY CONVERTER, ECO MODE and
SMART ACTIVE and in their main variants described in following paragraph.
Mode: ON-LINE
Normal Operation: the rectifier, drawing power from the mains power supply, supports the Inverter and charges
the batteries; the load is powered by the Inverter which provides a clean and secure supply, synchronised to the
bypass supply.
Emergency Operation: if the mains power supply wanders outside the permitted input range (voltage and
frequency), the rectifier is shut down and the Inverter is automatically powered by the battery set for the preset
back-up time and without disruption to the load. When the mains power supply returns, the rectifier gradually
starts up, charging the batteries and eventually powers the Inverter.
Operation from By-pass: if an Inverter overload exceeds permitted limits, or is manually shutdown, the load
automatically transfers to the emergency bypass via the static switch and without disruption to the load.
Mode: FREQUENCY CONVERTER
The UPS can be configured as a frequency converter (with “UComGP”), therefore when the input frequency is
50Hz the output frequency can be 60 Hz and vice versa. During this mode of operation the automatic by-pass is
disabled. The UPS can work in frequency converter mode with or without the batteries (must be set up with
“UComGP”).
Mode: ECO
The load is normally powered from the emergency bypass supply and the rectifier maintains battery charge.
When the mains power supply wanders outside the permitted input range, the load is automatically transferred
to the output of the Inverter until the mains power supply returns within range.
This mode is useful when powering loads that do not require the regulated no-break supply from the Inverter and
allows the system to achieve an efficiency up to 99%.
Mode: SMART ACTIVE
When the UPS is configured to operate in SMART ACTIVE mode, it automatically selects whether to operate in
ON-LINE or ECO mode.
The decision is made based on statistical calculations performed by the UPS and based on the quality of the
mains and bypass supplies: if the latter remains suitable for a certain period, the unit selects ECO mode,
otherwise it remains in ON-LINE mode.
Note: Multi Sentry working in parallel configuration, may not operate in Eco mode and Smart Active mode.

>6.1 PFC CONVERTER (ZERO IMPACT SOURCE)
The PFC Converter converts the AC voltage into a DC supply to power the Inverter; if the mains or alternative
power supply fails, the Converter will raise the battery voltage to a value suitable with which to power the
Inverter. The PFC control technology using Digital Signal Processor (DSP) microprocessors and IGBT power
semiconductors to achieve a low impact on the power supply source, low harmonic distortion and high input
power factor. A zero impact on the supply source is achieved due to the following characteristics:
Negligible Input Harmonics: upstream generators and transformers (including distribution) can be reduced
due to the negligible input harmonic distortion of 3% and high input power factor (> 0,99); also reduces the
size of a possible generator of the same upstream and distribution transformer MT/BT.
Delayed switching of UPS -t0-t1 (Power Walk in-start Delay): when the mains power supply returns, the UPS
delays switching of the input stage for a period of time that can be set between 1 and 120 seconds. This
function is particularly useful when the mains power supply returns after an interruption (or when the
generator set is started) and the source must supply various UPS or, more typically, multiple users.
Progressive rectifier start-up -t1-t2 (Power Walk-in duration): when the mains power supply returns,
absorption of the mains power supply progressively reaches the nominal value within a time period that
can be set from 1 to 125 seconds. This function is normally disabled.

>6.2 BATTERY CHARGER (Battery Care System)
The "Battery Care System" is a set of functions arranged to help extend the working life battery set and optimise its
performance.
Battery recharging: the UPS can be used with sealed lead batteries (VRLA), AGM, open-vented and NiCd
batteries. According to the type of battery used, three different recharge methods are available:
Recharging modes (selectable by “UComGP”)
MULTI SENTRY configurations
Floating: the charge state of the battery
is continuously monitored; when the
mains power supply is present, the
batteries are charged at a preset
voltage level and limited current relative
to the recharge time required and the
capacity of the battery itself.
Two-level recharge (standard): this
recharge is at limited current with two
levels of voltage. In the first instance, the
process uses a quick charge voltage,
whilst in the second stage a float charge.
This type of charging is mainly used with
open-vented batteries or other types
when an accelerated recharge time is
required.
Cyclical recharge: this recharge is
sometimes recommended by battery
manufacturers to prolong the battery life.
It consists of battery charge and
discharge cycles as indicated in the
diagram.
“Commissioning Charge”: this charge
method is useful every time new
batteries are installed in the UPS. By
increasing the voltage to 290 Volts for a
maximum of 24 hours, perfect
equalisation of the battery charge is
assured, thus guaranteeing a uniform
discharge and wear of the battery
monoblocks.

MULTI SENTRY
SPTMSTD2T16EREN
10
The various recharge methods and the preset voltage values are defined using "UComGP".
The presence of the external temperature sensor option will activate compensation of the voltage depending on
the temperature with the battery backup voltage (272 V for 20 battery blocks).
Battery test: during normal operation the battery is automatically tested at regular intervals. The battery test
can also be manually activated. The test is performed to ensure a limited battery discharge and impact on
overall life expectancy. If the test returns a negative result a warning is displayed on the UPS panel (or
remote panel, if installed).
Protection against slow discharges: for long runtimes and low load discharges, the end of discharge
voltage is raised to approximately 1,8 V/el. as recommended by the battery manufacturers to avoid a
deep discharge state.
Ripple current: recharge ripple current (residual AC component) is one of the most important causes of
poor battery reliability and reduced operating life. The UPS battery charger is a high-frequency design with
a negligible level of ripple current.
Battery recharge limit current: The battery recharge current is limited to a prefixed value of Cnom/8 (i.e.
12,5% Cnom).
Cold-Start: This feature allows the Inverter to be switched on and the load to be powered by the battery,
when the mains power supply is not present.
UPS without batteries: the UPS must always be operated with the batteries connected; if they are not
connected alarms will be generated and the UPS will not be able to perform to specification.

>6.3 INVERTER
The DC/AC Converter (Inverter) converts the direct current into a stabilised sinusoidal alternating current to
power the load. When the UPS is in ON-LINE mode, the load is always powered by the Inverter.
The Inverter is an IGBT (Insulated Gate Bipolar Transistor) based three-phase design; the IGBT is a transistor that
allows high commutation frequencies (>18 kHz) and, as a result, the Inverter provides a high quality output
voltage, with low noise levels and high operating efficiency. In addition, the DSP microprocessor controls,
guarantee static and dynamic performance under any operating condition:
Voltage adjustment
The output voltage can be adjusted using the independent phase control and DSP microprocessor; this enables
a better static and dynamic response. In detail:
a) static condition: the Inverter output voltage remains within ±1% for all variations of the input voltage within
the accepted limits;
b) dynamic condition: for load variations from 0 to 100%, the output voltage remains within ±3%, (within the
values defined by class 1 of the EN 62040-3 standard).
Frequency adjustment
The Inverter output frequency is generated autonomously by an internal oscillator, in synchronisation with the
bypass supply. Frequency stability is operating condition dependent:
a) Frequency stability
a. With mains power present: the internal oscillator follows any frequency variations in the bypass supply
and in relation to the preset value - normally ±5% (configurable from ±0,25% to ±10%).
b. With no supply present: the Inverter autonomously generates the frequency of the output voltage with
a stability of ±0,01%.
b) Frequency variation speed
The maximum Inverter output frequency variation (to lock to that of the bypass supply) is 1 Hz/s (adjustable
from 0,5 to 2 Hz/s).
Distortion of the output voltage
Inverter output waveform distortion with a linear load is maintained within ±1%. Within a non-linear load, as
defined by the EN 62040-3 standard, output voltage distortion does not exceed 3%.
Overload
The Inverter is sized to provide a power overload for a limited length of time (see the limits indicated in the
“Technical specifications table”).
When the time period or power limits are exceeded, the load is transferred to the bypass supply.

MULTI SENTRY
SPTMSTD2T16EREN
12
Short circuit capacity
If a current surge occurs whilst the UPS is operating from the batteries (VOUT <100 Volt), the Inverter will carefully
analyse the output voltage and current in order to distinguish if the short circuit is genuine or an overload. As for
the overload limits refers to technical data table. In case UPS will detect short circuit (VOUT<100 V):
During battery operation (mains power supply failure) the Inverter can supply a current limited to 150% for 500
ms.
With mains present UPS will changeover bypass supplying limited current for 1 sec. (current >103% and output
voltage <160 Volt). Unlike, if current is greater than 150%, but voltage within the limit, UPS will not discriminate
the short circuit, continuing to feed the load for one minute; during this time upstream or downstream
protections outside UPS should be able to blow up.
The table below recommends the sizing of the various protection devices located downstream of the UPS in
order to guarantee their selectivity even in the event of a power failure:
Output protections (values recommended for selectivity)
Rapid fuses (GI)
In (Nominal current)/7
Magnetothermal switches (Curve C)
In (Nominal current)/7
Ultra-rapid fuses (GF)
In (Nominal current)/2
Output voltage symmetry
Under all conditions, output voltage symmetry is maintained within ±1%, for balanced loads and ±2% for
unbalanced loads of 100% (e.g. one phase with nominal load, the other two with no load).
Phase shift angle
The three-phase Inverter output voltages have a guaranteed phase separation angle of 120° ± 1° for balanced
loads and 100% for unbalanced loads.

>6.4 STATIC SWITCH (Automatic Bypass)
A static switch is an electronic device that can automatically transfer the loads connected to the UPS to the
bypass supply in an emergency for example when:
a) Inverter overload limits are exceeded;
b) internal over temperature limits are exceeded;
c) the Inverter fails;
d) DC voltage goes outside the permitted range.
If at the time of switchover, the inverter voltage is not synchronised with that of the auxiliary power supply, the
transfer will take place with a delay of around 20 ms; in consideration of the various types of loads, this delay can
be set with “UComGP” (10÷100 ms) or the switchover can be inhibited if there is no synchronism.
Emergency Supply Voltage
Transfer to the emergency supply only takes place if the voltage and the frequency are considered 'suitable' for
the load and the limits for transfer can be set on-site by the UPS user.
Voltage range: ±10% (settable from -20% to +15%);
Frequency range: ±5% (settable from ±0,25% to ±10%)
Overload
The static switch has no over current fast protection devices to guarantee maximum continuity.
Overcurrent protection shall be provided by protective devices within the overall installation to ensure UPS
compatibility.
UPS static switch is sized to support the following overload periods; above these limits UPS is automatically turned
Off:
110% permanently
125% for 60 minutes
150% for 10 minutes
Thyristors with I2t (Tj=25°C) = 11.250 A2S for 10-20 kVA three-phase and 25.000 for 10-20 kVA monophase.
Thyristors with I2t (Tj=25°C) = 20.000 A2S for 30 kVA and 25.000 for 40 kVA.
As for further overload limit details refers to technical data table.
Redundant Auxiliary Power Supply for the Automatic Bypass
The UPS is equipped with a redundant auxiliary power supply to allow the automatic bypass to function even if
the main power supply has failed.
If the UPS fails in addition to the main power supply, the load is powered through the automatic bypass.
The multi processor card and control panel are not powered, and for this reason, all LEDs and the display are off.
