4. APPLICATIONS

The UPSs of the Master HE series are suitable for all applications requiring protection of the critical load, from simple
installations to more complex systems where a higher level of reliability and maintainability is required.

Data Centers and Telecom m unicatio n: the u nint errup tible power system c an gr ow t ogether w ith y our busi ness since t he
basic system can be expanded with up to eight units connected in parallel without compromising the initial investment.
Furthermore, greater levels of reliability and maintainability can be achieved with the more advanced configurations such
as the “Dual Bus” and “Dynamic System Expansion”.

Industrial processes and electro-medical systems: the UPS is particularly suitable for application with industrial
processes and the power supply to electro-medical systems, thanks to its design principles and technical features, such
as for example:

• inverter with output transformer guaranteeing isolation of the load from mains interference in all conditions;

• high short circuit and overload capacity;

• high battery recharging capa city , enabling ap pli cation s with di fferent kinds of batt eries (se aled, v ented or Ni cke l

Cadmium) with long back-up time.

Emergency systems: the Stand-by O FF mode of oper ati on can be selected to activate the emergency back-up function,
as defined by standard EN 50171 (Central Power Supply Systems).

5. CONFIGURATIONS

The following configurations ar e available:

Single UPS

The single version of the system, nor mally used for simple in stallations, can be ex tended to up to 8 units to sat isfy increases
in load power or to introduce a level of redundancy. The same group can function as a frequency converter of 50/60 Hz
and vice versa with or without battery by a simple arrangement that can be done in site (refer to dedicated paragraph).

Parallel configuration

Up to 8 UPSs can be c onne cte d in parallel to increase the pow er of the uninterruptible power system ( power parallel) or to
enhance its reliability (redundant parallel).
The system is defined as “redundant parallel” when the block of one or several UPSs does not determine the loss of the
power supply.
All the UPSs fed the load simultaneously with automatic sharing of the current.

UPS in 1+1 redundant configuration

UPS single module

MASTER HE

SPTMHEE3T16FREN

The units exchange information on the operating status and the sync signals by 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.

The “Hot System Expansio n ” (HSE) feature means that a new UPS can be ad ded t o t he s y stem 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.

In configurations with more t han tw o units, to i mprove the nor mal and ex traordinary mainten ance operatio ns, it is adv isable
to install an external maintenance by-pass and to inhibit the UPS’s internal one.

The UPS will be equipped with terminal to connect the following auxiliary contacts:

• External Maintenance Switch

• External Load Output Switch

The parallel system may function w ith a separat e battery or a single battery, that is, one battery shared by severa l UPSs.
In the case of loss of redundancy the system has an alarm message.

Parallel configuration up to 8 units

In parallel systems, the “Efficiency Control System” (ECS) function enables the UPS to be switched on and off
automatically according to lo ad variations, w hile retaining the l evel of redundan cy defined by the oper ator. This signifi cantly
reduces the total energy dissipated by the system since only those UPSs required to power the connected loa d remain
switched on (for example during the night or at weekends).

MASTER HE

SPTMHEE3T16FREN

Centralized By-pass: Master Static Bypass (MSB)

The configuration with centralized By-pass comprises up to UPS modules (MHE NBP type) having not embedded static
switch connected in parallel and a separated By-pass section. The By-pass unit is equipped with a static switch which
automatically switches the power supplied to the load by the whole system directly to the mains power supply and vice
versa. Switching is needed during system maintenance operations, or when the whole system is unable to support the
load due to overloads or output short circuits over the current limits.
This configuration assumes the selection of n UPS modules having the same power rating.

The following site prescriptions should be taken into account for the site planning:

• Distance between UPS module and central by-pass shall not exceed 40 meters

• Communication bus cable between units shall not exceed 50 meters

• Total communication ring (UPS units and by-pass) shall not exceed 150 meters

• Battery can be arranged as common or separate (same as distributed parallel system)

• Maintenance bypass is part of the system either embedded in Riello UPS solution (Fig. 1) or supplied by the

customer together with all Input/Output/distribution switches (Fig. 2)
This manually control switch will enable the load feeding directly from the mains insulating the UPS whenever
there is an intervention on its critical parts.

According with site arrangement and UPS modules pairing layout, it will be possible to arrange for MSB having switches
inside (Fig 1) or MSB without any breaker, leaving the coupling arrangement to the customer which shall ensure handy
and safe operations during maintenanc e. (Fig 2)

These two different layouts modify the system current reading but it won’t affect the system operation.
Below we resume the two different scenarios according with system operations either on Inverter or bypass mode:

Dual Bus System (UGS)

Two independent systems can be configured in Dual Bus with a single or separate power source.
The synchronization option (UGS) keeps the outputs of the two systems constantly synchronized, regardless of the input
variations and when the system is powered by the battery.
Each system comprises up to a maximum of 8 parallel UPSs. Finally up to 16 units might be mutually synchronized.
This system has been designed for configurations that use the STS (Static Transfer Switch) since it guarantees switching
from one continuous source to the other without disturbances to the loads.

Note: UGS may operate with parallel systems either in distributed or centralized by pass arrangement. Refer to dedicated
manual for installation and operations details.

MASTER HE

SPTMHEE3T16FREN

Dynamic Dual Bus System (PSJ)

Two independent systems (up to 4 units each) can be connected in a “Dynamic Dual Bus” configuration by means of the
PSJ (Parallel System Joiner) option.

This enables the two systems to be joined to form a single system when, for example, part of one system is undergoing
maintenance and it is felt appropriate to use the redundant UPS for both bars of the load. The synchronization and the
equal distribution of power is guaranteed by the PSJ.
This characteristic provides an extreme flexibility of the systems in case of maintenance or when is necessary to modify
the redundancy level between the two bus.

Note: PSJ operates with distributed parallel systems, only.

Frequency Converter

Units in standard configuration at 400 V can operate as frequency converters (50/60 Hz and vice versa), whether or not
batteries are present. This feature can be set at the commissioning. The bypass is inhibited in this configuration and
frequency converters with operating voltages other than 400 V, such as 440 V, 460V, etc. can be supplied on request.
With such configuration the UPS can be used without input neutral cable.

Note: For Frequency converter applications please contact your sales representative to ensure that converter layout and
technical arrangements comply with all tender requirements.

6. UPS DESCRIPTI ON

The uninterruptible power supply can be set to operate in four operating modes: ON-LINE, STAND-BY ON, SMART
ACTIVE and STAND-BY OFF.

Mode: ON-LINE

• Normal Operation: The rectifier draws energy from the mains to power the inverter and keep the batteries

charged; the inverter powers the load with voltage and frequency stabilised and in sync with the by-pass mains,
if appropriate.

• Emergency operation: when the main s power supply goes out of the pre-set limits, the rectifier switches off an d

the inverter is powered fr om the batt ery for the envisage d back-up t ime without a ny distur bance to the load. When
the mains power supply is rest ored, the Rectifier star ts to operate gradually (power walk in), pow ering the batteries
again and charging the inverter

• By-pass operation: in the event of an inverter overload beyond the envisaged limits, or a manual shutdown, the

load is automatically transferred onto the by-pass mains by means of t h e Static switch without any disturb an ce to
the load.

Mode: STAND-BY ON

The load is normally powered from the by-pass mains, the rectifier keeps the batteries charged. W hen the mains goes
outside the preset range, the load is transferred automatically onto the inverter (within three milliseconds) until the mains
returns to a suitable level.
This mode is suitable for powering loads that are not sensitive to mains interference, thus allowing increased system
efficiency of up to 98%.

Mode: SMART ACTIVE

When the Master HE is configured in SMART ACTIVE mode, it automatically defines whether to operate in ON-LINE or
STAND-BY OFF mode.

This is done by monitoring the by-pass mains: if this remains suitable for a defined period, the system sets itself to STAND ­BY ON mode; otherwise it remains in ON-LINE mode.

Mode : STAND-BY OFF

When the mains power supply is present, the rectifier keeps the batteries charged and the inverter is switched off. When
the mains fails, the rectifier switches off and the inverter is activated in approx. 200 ms, using the battery energy.
This application is suitable for the power supply of emergency lighting, as defined by standard EN 50171.

6.1. AC/DC Converter

The AC/DC Converter conver ts th e alter nate volta ge int o d irect v oltage to power the inverter at nomina l loa d a nd to charge
the batteries. The input stage of Master HE UPS is realized with a t echnol ogy such a s to reduc e the har monic s of cur ren t
rejected into the mains by up to 3% and increase the power factor up to the unit from 10 to 100% of the load (see the
tables with the Technical Data at the end of the present specifications).

6.1.1 Easy Source

Master HE is designed in order to reduce at minimum the impact on the mains source or on the upstream Generator Set.

In detail the features are as follow:

• Input Harmonics: thanks to a low input harmonics content of the and the high power factor, the installation

costs are reduced as well as the sizing of a possible generator set upstream.

• Power Walk-In duration: when the input vo ltag e is app lie d to the rectifier, as per example after a mains power

failure, this reaches the nominal power progressively in a programmable time from 0 to 30 seconds.

• Power Walk-in start delay: in parallel configurations the start-up of the rectifiers can be delayed to reduce the

impact to any generator located upstream. The delayed start-up is programmable up to 120 seconds.

Example of calibration from the rectifiers in a parallel system

• Inhibition of the battery charge current: while the UPS is operating with a generator set, battery recharging

can be excluded and all the available power can be used to feed the load.

• Inhibition of bypass synchronism: in case of the generator set with a very unstable output frequency, the

Inverter synchronization with bypass can be inhibited. In such as case the inverter generates an output voltage

in the free running mode by us ing th e internal oscillator. Consequently, the tr ansfer of the load on the bypass is

not allowed.

The “battery recharge current” and “Inverter Synchro with bypass” inhibitions are activated by a remote contact of the
generator set connected to the optional Rely Card (see Chapter 12 – Options ).

6.1. DC/DC Converter

The DC/DC converter takes the output direct current from PFC converter to allow the battery recharge. Such a system
closes inside it a STEP-UP/STEP-DO WN converter that takes care o f the charging an d discharging of the battery, reduc ing
drastically the current ripple in the battery. The DC/DC converter is also characterized by the following fundamental
function:

6.2.1 Battery Care System

The “Battery Care System” is a set of functions to control, manage and preserve the battery as long as possible.

a) Battery Recharging: This UPS is suitable for hermetic lead batteries (VRLA), AGM, open vase and Ni-Cd.

Depending on the battery type, two recharge methods are available:

• Cyclical rechar ging ( factory set): the state of the battery ch arge is k ept co nstantly under cont rol an d w hen
the charge level drops below the establi she d lev el, a re char g e cyc le start s up automatically following the IU
characteristic (EN 50272-2). In any case the UPS automatically runs a top-up charge cycle every 24 hours.

• Two level recharging (configurable): this recharge is carried out with two levels of current at two voltage
levels following th e IU

1 U2

characteristic (EN 50272-2). During the first phase the charging takes place at

the rapid charge voltage (U

1

), followed by a second phase at the floating charge level (U2). Both these
recharge values are ensured with temperature compensation of the recharge current as requ ired by the
battery manufacturers so that battery life is not jeopardize. This type of recharge can be configured on-site
and is mainly used with open vase or Ni-Cd batteries.

b) Battery test: in normal operating conditions the battery is checked automatically at regular intervals or on

manual command. The test takes place without appreciably discharging the battery, in complete safety for the
load and without compromising the battery service life. If the test has a negative outcome, a report signal will
appear on the UPS panel and remotely.

c) Protection against slow discharge: in the event of discharges of long duration and low load, the end of

discharge voltage is raised to approx. 1.8 V/el as prescribed by the battery manufacturers so at to avoid
damaging the batteries.

d) Current Ripple: Thanks to the STEP-UP/STEP-DOWN converter, that provides to recharge and discharge the

battery, the current rippl e in the battery is extremely reduced. This feat ur e el im inat es one o f the main causes of
reduced battery reliability.

6.2. DC/AC Converter

The DC/AC converter convert s direct voltage in to stabilized, alternate s inusoi dal curre nt to supply the load. With the UP S
in ON-LINE mode, the load is always powered from the inverter.

This comprises a three phase inverter with IGBT (Isolated Gate Bipolar Transistor), a transistor that allows high switching
frequencies (>20 kHz) and consequently low consumption and low noise.
The inverter output is connected to the transformer, thus ensuring galvanic isolation between output and battery.

Voltage regulation

Output voltage is regulate d by using the inde pendent p hase control , a characteri stic that all ow s a better static and dy namic
response. In detail:

a) Static condition: the output voltage from the inverter remains within ±1% for all the input tension variations

within the permissible limits;

b) Dynamic condition: for load variations from 0 to 1 00%, the output volt age remains w ithin ±5% below the v alues

defined by class 1 of standard EN 62040-3.

MASTER HE

SPTMHEE3T16FREN

13

Frequency regulation

The inverter output frequency is generated autonomously by an internal oscillator in synch with that of the by-pass mains;
the frequency stability towards the load therefore depends on the operating conditions:

a) Frequency stability

a. With mains available: the internal oscillator follows the variations in frequency of the by-pass mains,

according to the set value, which is normally ±2% (can be calibrated form ±1% al ±6%).

b. W ith mains not available: the inverter generates the output current frequency autonomously with a stability

of ±0,05%.

b) Speed of frequency variation

The maximum output fr eque ncy variatio n of the invert er t o rea ch onto t hat of the bac kup by -pass mains is 2Hz/s
for the single UPS and 1Hz/s for the parallel version.

Output voltage distortion

The regulation of the inver ter guarantees the o utput voltage distort ion with linear l oads within 1% (max imum 2% with battery
nearly discharged). W ith non-linear loads, as defined by standard EN 62040-3, the output voltage distortion does not
exceed 3%.

Output power

The Inverter is sized to supply 100% of active power with nominal load pf 1 in the temperature operating range without
downgrading.
MASTER HE supplies capacitive loads with PF form 1 to 0,9 with no any power downgrading applied.

Overload
The inverter is sized to supply a power overload (kVA) of 110% for 1 hour, 125% for 10 minutes and 150% for 1 minute,

on the three phases. On one phase, the limit is 200% for 6 s.
If the time or power limits are exceeded, the load is transferred onto the by-pass mains.

Short circuit capacity

In the event of a short circuit on the load and with power supply from the battery, the inverter can supply a current limited
to 180% for 1 s in the event of a short circuit on the three phases, and 300% for 1 s in the presence of a short circuit
between phase and neutral.

Symmetry of output voltage

In all conditions, the sy mmetry output v oltage i s guara nteed w ithin ±1% , for bala nced loads and ± 2% f or 100% u nbalan ced
loads (e.g. one phase at nominal load, the other two without load).

Phase displacement

The inverter three phase output voltages are guaranteed with a phase shift angle of 120° ±1° for 100% balanced and
unbalanced loads.

MASTER HE

SPTMHEE3T16FREN

6.3. Static switch

The Static Switch is an electronic device that transfers the load onto the by-pass mains without any break in power in the
following circumstances:

a) manual shutdown of the inverter;
b) exceeding of the inverter overload limits;
c) exceeding of the internal over temperature limits;
d) inverter fault;
e) DC voltage outside the admitted range.

If at the time of switching the inverter voltage is not in sync with that of the by-pass mains, the transfer takes place with a
delay to avoid possible damage to the load. However this value can be adjustable to cover all the requirements of the
various types of load Refer to Technical data table.

By-pass mains voltage

Transfer onto the by-pass mains only takes place if the v oltage and frequency are consider ed “suitable” to power the load.
The limits of acceptability are defined by the user in relation to the connected load:

• Voltage window: ±10% (can be calibrated from ±5% to ±25%);

• Frequency window: ±1 Hz (can be calibrated ±1 Hz to ±6 Hz).

Overload

In order to guarantee th e maximum of service cont inuity, the static sw itch does not hav e protection f or overload. This allows
the compatibility w ith any typ e of syst em, commi ssioning t o protection devices , externally installe d, the sel ectivity ensuring.

The UPS Static switch is sized to support the following overloads:

• 110% for 60 minutes

• 125% for 10 minutes

• 150% for 1 minute

The short-circuit capacity may also vary according to the load (see table in the Technical Data section).

Hardware

Two slots are available inside the device, at the bottom, to house two of the following communication options:

a) NetMan 102 Plus: network agent for the management of the UPS connected directly on the LAN 10/100Mbps

using the main protocol of network communication (TCP/IP, HTTP and SNMP). A MODEM can also be
connected to the same device.

b) Netman 202 Plus: network agent like Netman 102 Plus, but improved with USB host, SNMP v1 and v3,

maximum expandability and firmware upgradeable via USB port FTP and http.

c) MultiCom 302: Modbus/Jbus protocol converter by means of RS232 or RS485 output for the monitoring of

UPSs in BMS (Build Management System). It also manages a second independent RS232 serial line that can
be used to connect other devices such as NetMan Plus or a PC.

d) MultiCom 352: a device that makes it possible to connect two devices to a single UPS serial port. It can be

used in all cases where several serial connections are required for multiple interrogation of the UPS.

The communication cards can be used simultaneously in various combinations to achieve greater flexibility and therefore
enhanced services, as can be seen in the following example:
