MASTERYS BC 15-40 kVA - Ref.: IOMMASBCXX09-EN 01

1.1. IMPORTANT

• This document provides important instructions for the safe use, movement and connection of the MASTERYS BC uninterrupt­ible power system (UPS).

• SOCOMEC retains the full and exclusive ownership rights over this document. Only a personal entitlement to use the docu­ment for the application indicated by SOCOMEC is granted to the recipient of this document. The reproduction, modifi cation,
distribution of this document either partially or wholly and in any way is strictly prohibited except upon Socomec’s express prior
written consent.

• This document is not a specifi cation. SOCOMEC reserves the right to make any changes to the information provided without
prior notice.

• The unit must only be installed and activated by qualifi ed technical personnel who have been authorised by SOCOMEC.

The UPS MUST only be moved by two people at least.
They MUST take position at the sides of the UPS with respect to the direction of movement.

• The unit must remain in a vertical position at all times.

• Connect the PE ground conductor fi rst before making any other connection.

• Do not expose the UPS to rain or liquids in general. Do not insert foreign bodies.

The installer is responsible for implementing the backfeed protection with the use of AC input line isolation devices
external to the UPS (see section 2.4.1).

Before working on this circuit

- Isolate the Uninterruptible Power System (UPS)

- Then check for Hazardous Voltage between all terminals
including the protective earth

Risk of Voltage Backfeed

• For the purpose of warning electrical technicians against backfeed situations not caused by the UPS, which may arise when a
particular load fault is present while the UPS is operating in stored energy mode, or while unbalanced loads are supplied through
a particular power distribution system e.g. an impedance grounded IT system, the installer must attach the labels provided to
all primary power isolators installed remotely from the UPS area and on external access points, if present, between the said
isolators and the UPS.
In particular the label must be attached to the external AC input line isolation service (backfeed insulation).

• Keep this manual in a convenient place for future consultation.

• If the unit fails, it must only be repaired by authorised technicians who have been specially trained for this purpose.

• This equipment complies with European Community directives for industrial equipment and bears the approval mark

• The UPS requires three-phase plus neutral input connections (3P+N).

• Do not connect the output neutral to ground. The UPS does not modify the neutral setup of the system; the use of an isolation
transformer is required should it be necessary to modify the neutral setup downstream of the UPS.

• Before connecting any external battery cabinets, ensure they are fully compatible with the UPS model used.

• The use of external battery cabinets not supplied by the manufacturer is not recommended.

• Switch o and isolate the UPS and wait for 5 minutes before removing the protection panels in order to carry out work on parts
under dangerous voltage.

• Risk of explosion if the batteries are replaced with others of the wrong type.

• Used batteries must be disposed of at authorised waste disposal centres.

It is very dangerous to touch any part of the batteries as there is no insulation between the batteries and the mains
power source.

CAUTION!
A battery can present a risk of electrical shock and high short circuit current.

WARNING!
This is a category C2 UPS product. In a residential environment, this product may cause radio interference, in which
case the user may be required to take additional measures.

Caution! Use type B selective (S) circuit breakers. Load leakage currents are added to those generated by the UPS and during transitory

phases (power failure and power return) short current peaks may occur. If loads with high leakage current are present, adjust the di erential
protection. It is advisable in all cases to carry out a preliminary check on the earth current leakage with the UPS installed and operational with
the defi nitive load, so as to prevent the sudden activation of the above switches.

The UPS is designed for transitory overvoltages in category II installations. If the UPS is part of the building’s electric
circuit or is likely to be subject to transitory overvoltages in category III installations, further external protection must
be provided, either on the UPS or in the AC power supply network connected to the UPS. Additionally, the ‘surge
arrestor’ option, specially designed to protect against residual overvoltages in category III installations, can be instal­led in the external manual bypass cabinet. If used, the distance between the UPS and the centralised 4 kV SPD
protection device type 1 must be Up ≤ 4kV is ≥ 15m.

In the event of three-phase distorting loads connected in output, the current on the neutral conductor may have a
value that is 1.5-2 times the phase value (also for the input bypass). In this case, size the neutral cables and the input/
output protection adequately.

WARNING!
This is a product for commercial and industrial application in an industrial environment - installation restrictions or

additional measures may be needed to prevent interference.

IMPORTANT!
Protective earthing conductor (PE) must have sufficient current-carrying capacity.
The PE cable core size must be chosen according to the PROTECTIVE CURRENT RATING of the earth circuit which

depends on the provision and location of protective overcurrent devices.

2. UNPACKING AND INSTALLATION OF THE UNIT

2.4.1. Backfeed protection

If the UPS does not have an automatic protection device against current backfeed, the operator/installer must add a warning label
to all the mains power disconnecting switches installed at a distance from the UPS area. This serves to remind technicians of the
fact that the circuit is connected to a UPS (see the SAFETY section in paragraph 1 of this manual and paragraph 4.7.3. of the
EN62040-1 2009-05 standard).

The label is supplied with the system.
The backfeed protection device may be built into the system (only on specific request), or an electromechanical switch may be

installed externally in the input of the UPS.

• If the UPS incorporates this protection, proceed with the connections as described in paragraph 2.5 of this manual.

• To install the external backfeed protection it is necessary to use the BKF card and an external electromechanical switch that should
be installed . For further information on the connection and the type of remote switch, please read paragraph 9.7 of this manual.

WARNING
The neutral is not disconnected as, even in the event of a single fault on the UPS, it never has high potential when

the mains and/or auxiliary power supplies are disconnected upstream. This is to prevent transformation of the power
source to the UPS every time there is a power failure.

If under certain irregular conditions, or due to the installation upstream (e.g. undetected and protected earth fault, or
high leakage in a phase, or with IT systems) there is a hazardous potential on neutral, a suitable isolating switch must
be provided on the neutral as well, or else there must be a detection, signalling and protection system.

NOTE
For equipment with separate Emergency Mains, the neutral of the Emergency Mains line must be electrically common

with the neutral of the main input feed line.

2.8. ISOLATION TRANSFORMER

If an external isolation transformer cabinet is required, the following instructions should be followed:

• Refer to chapters 1 and 2 of this manual for indications on moving and installing the cabinet.

• See paragraph 2.4 for details about protection devices.

• The protection cable marked with the ground symbol is connected directly to the distribution panel.

• The transformer can either be connected to the UPS input or output.

The UPS must not operate without the neutral connection to the input.

The transformer cannot be connected to the output on individual UPS units connected in parallel configuration.

For connection details refer to the transformer terminal board diagram.

2.9. UPS PARALLEL CONFIGURATION

2.9.1. General

Parallel connection enhances UPS system reliability, performance and power.
All models can be installed in parallel configuration provided they have the special parallel kit that can be installed in the factory or

later by specialist personnel.
UPS modules for parallel operation are identical to standard UPS modules, as a result safety, shipping and installation recommen-

dations in

'Safety' and 'Unpacking and installation of the unit' chapters.

For 3/1 versions only two units in parallel are allowed.

2.9.2. Installation

UPS units operating in parallel are interconnected using control cables B (fig. 2.9-1) and are configured differently depending on
the position they are assigned.

For this reason the units have a position label C (Fig. 2.10-1):

• The LEFT label means that the unit must be positioned to the left.

• The RIGHT label means that the unit must be positioned to the right.

• The INTERNAL label (used only on systems with three) means this unit must be positioned between the two other cabinets.

The control cables supplied allow a maximum distance of about 3 metres between the UPS units. This gives enough room for an
external battery cabinet to be inserted beside each UPS.

2.9.3. Power connections

• The power supply to each unit must be protected as indicated in the table in paragraph 'Electrical requirements'.

• The cross section and length of the input and output cables must be identical for all units.

• The phase rotation must be the same for each unit connected in parallel and also on any external manual bypass line.

• Cables of the same length and cross section must be used for the connection between the general power switch A, the switches
C and the respective UPS units. The length of the cables from A to each UPS module must not exceed 25 metres.

• The cables from the UPS module to switch F must be of the same length (max. 15 metres) with multi-core cables.

•

If a differential switch is installed on the mains power switch (optional), it must be inserted upstream from the distribution panel (detail H),
it must be a selective type and the trigger value must be 0.5 A multiplied by the number of UPSs connected in parallel.

Only activate switch D after carrying out the procedure for switching onto the maintenance bypass.

Only activate switch E after turning off the UPS.

In order for units connected in a parallel configuration to operate correctly, control cables are required to exchange data between
the various UPS units making up the parallel system, for management of correct load sharing and synchronisation logic.

The cables in question are supplied with the UPS in the case of a standard parallel setup or are attached to the parallel kit in the
case of a later system upgrade.

Parallel configuration must only be activated by SOCOMEC qualified personnel; in each case arrange the control cables in
the relevant cable run as shown in figure 2.9.4-1, leaving the connector(s) unconnected (in the central UPS one incoming and one
outgoing control cable must be used).

2.11. EXTERNAL BATTERY CABINET CONNECTION

If the UPS has internal batteries connecting external battery cabinets is prohibited.

Position the battery cabinet next to the UPS.

Before carrying out any operations ensure that:

• the battery fuses located inside the battery cabinet are open;

• the UPS is not live;

• all mains or battery switches are open;

• the switches upstream of the UPS are open.

• Remove the terminal board protection.

• Connect the ground cable.

• Connect the cables between the UPS terminals and the battery cabinet terminals, strictly observing the polarity of each individual
string and the cross-sections indicated in table 2.4.

Use double insulated cables or the cables supplied with the unit to connect the UPS to the battery cabinet. The
length L of battery cable must not be more than 8 metres long (if L > 8 m, please contact the support service).

Cabling errors with inversion of battery polarity may cause permanent damage to the equipment.

• Replace the terminal board’s protection.

If using cabinets not supplied by the UPS manufacturer, it is the installer’s responsibility to check the electrical compa­tibility and presence of appropriate protection devices between the UPS and the battery cabinet (fuses and switches
of sufficient capacity to protect the cables from the UPS to the battery cabinet). As soon as the UPS is switched on
(before closing the battery switches) the battery parameters must be verified accordingly (voltage, capacity, number
of elements, etc.) on the mimic panel menu. If the values indicated on the battery cabinet data plate are different from
those shown on the mimic panel use the SERVICE > CONFIGURATIONS menu to correct the settings.

3. MODES OF OPERATION

3.1. ON LINE OPERATION

A special feature of the MASTERYS BC series is the ON LINE double conversion feature in conjunction with low distortion mains
power absorption. With ON LINE mode the UPS is able to supply a voltage that is fully stabilised in frequency and amplitude,
regardless of any interference in the mains power supply within the most stringent classification of UPS regulations.

ON LINE operation provides three operating modes according to mains and load conditions:

• Normal mode

This is the most frequent operating condition: the energy is drawn from the primary mains power supply and is converted and used
by the inverter to generate the output voltage to power the loads connected.

The inverter is constantly synchronised in frequency with the auxiliary mains to enable load transfer (due to an overload or inverter
shutdown) without any break in the power supply to the load.

The battery charger supplies the energy required to maintain or recharge the battery.

• Bypass mode

In the event of inverter failure the load is automatically transferred onto the auxiliary mains without any interruption in the power
supply. This procedure may occur in the following situations:

- in the event of a temporary overload the inverter continues to power the load. If the condition persists the UPS output is switched
on to the auxiliary mains via the automatic bypass. Normal operation, which is from the inverter, returns automatically a few seconds
after the overload disappears.

- when the voltage generated by the inverter goes outside the limits due to a major overload or fault on the inverter.

- when the internal temperature exceeds the maximum value allowed.

• Battery mode

In the event of a mains failure (micro interruptions or extended power cuts), the UPS continues to power the load using the energy
stored in the battery. The Expert Battery System keeps the user constantly informed on battery status and the back-up time available.

3.2. OPERATION IN HIGH EFFICIENCY MODE

The UPS allows the selection of a programmable ‘economy’ operating mode that can increase overall efficiency by up to 98% for
energy saving purposes. With this mode of operation, specific daily or weekly time intervals can be selected and programmed to
power the applications directly from the auxiliary mains. If the power supply fails the UPS will automatically switch onto the inverter
and continue to supply power to the load by drawing energy from the battery.

This mode does not provide perfect stability in frequency and voltage like the ON LINE mode. Thus the use of this mode should
be carefully evaluated according to the level of protection required by the application.

The Eco Mode operation provides very high efficiency, since the application is powered directly from the auxiliary mains via the
automatic bypass in normal operating conditions.

3.3. OPERATION WITH MANUAL MAINTENANCE BYPASS

If the maintenance bypass is activated using the appropriate procedure the load is powered directly from the maintenance bypass,
while the UPS is separated from the power supply and can be switched off.

This operating mode can be selected for maintenance to be carried out on the system so that the necessary actions can be perfor­med by service personnel without having to disconnect the power supply to the load.

The external maintenance bypass may be placed on the general distribution panel when the UPS is installed, or by installing the
bypass panel that is supplied on request.

If the UPS has an input for the auxiliary power supply the Q2 switch must be connected to this input and the main power supply
input must be disconnected on the control panel.

If the maintenance bypass is activated with the appropriate procedure the load is powered directly from the maintenance bypass,
while the UPS is separated from the power supply and can be switched off.

This operating mode can be selected for maintenance to be carried out on the system so that the necessary actions can be performed.

4.2. SWITCH FUNCTIONS

Input switch Q2

The input switch provides the primary power supply to the UPS.
In normal operating conditions it should be in position 1 ON.
The position 0 OFF will cause the batteries to discharge.
In a configuration with separate mains the switch only interrupts the rectifier power supply.

Output disconnecting switch Q6

The disconnecting switch Q6 has three positions with the following functions:

• Position 1 UPS: this is the position for normal UPS operation for a continuous power supply to the load;

• Position 2 MANUAL BYPASS: This position should only be selected for standard or special maintenance operations (manual
bypass); the load is connected directly to the mains power supply. It may be used in the event of a UPS failure to power applications
from the auxiliary mains while awaiting the intervention of technical personnel;

• Position 0 OFF: This completely isolates the UPS output by removing the voltage from the applications in any operating conditions.
It is used for the emergency shutdown of the system (internal ESD).

Battery switch Q1 (UPS batteries)

When closed, this switch connects the UPS batteries to the DC/DC converter stage to power the inverter in the event of a mains
failure. The normal operating position is 1 (closed).

7. OPERATING PROCEDURES

7.4. SWITCHING ONTO MANUAL BYPASS

Switching onto manual bypass creates a direct connection between the UPS input and output, completely excluding the equipment
control element.

This operation is performed in the event of standard maintenance on the equipment, so as not to remove the power supply from
the load, or in the event of a serious failure while waiting for the equipment to be repaired.

• From the mimic panel set the HIGH EFF. MODE command from the IMMEDIATE COMMANDS menu.

• Wait for the command to be executed (bypass line on the M1 display on). If this does not take place, suspend the operation (the
auxiliary mains is not suitable for the load).

• Set disconnecting switch Q6 to position 2.

• Set switch Q1 and/or battery switches to position 0 (battery circuit open).

• Open the switch Q2.

If there is an external manual bypass carry out the procedure described above before activating this switch.

7.5. RETURN TO NORMAL MODE

• Set switch Q2 to position 1 (input mains ON).

• Set switch Q1 and/or the external battery switches to position 1 (battery circuit closed).

• Activate the start procedure from the commands menu on the mimic panel.

• From the mimic panel set the HIGH EFF. MODE command from the IMMEDIATE COMMANDS menu.

• Check that alarm A06 is not present (if the alarm is present, resolve the problem before continuing).

• Set disconnecting switch Q6 to position 1 (inverter in output ON).

If there is an external manual bypass, put the switch to position OFF.

• From the mimic panel set the NORMAL MODE command from the IMMEDIATE COMMANDS menu.

7.6. EMERGENCY SHUTDOWN (ESD)

Should it be necessary to interrupt the continuous power supply provided by the UPS quickly (emergency shutdown), this can
be done by putting disconnecting switch Q6 to position 0 (zero) or, where applicable, by activating the emergency button/switch
connected to the ADC PCB.

The UPS output can only be electrically disconnected by means of Q6.
If the UPS is operating from the manual bypass with mains present, shutdown using the emergency button does
not interrupt the power supply to the load. In emergency conditions all the power supply sources upstream of the
UPS must be disconnected.

8. CONNECTIVITY AND COMMUNICATION OPTIONS

8.1. MULTILEVEL COMMUNICATION

MASTERYS BC can manage a variety of serial, contact and Ethernet communication channels simultaneously.
The various cards and signalling accessories are inserted in the two standard communication slots. This gives MASTERYS BC

immediate interfacing and integration flexibility as soon as the unit is installed with no need for trained personnel.

As each channel is independent, simultaneous connections can
be made to satisfy the different levels of signalling and remote
monitoring.

See the operating procedures paragraph to access the detailed
functions of the cards installed in the slots.

8.2. ADC CARD

To be installed in one of the two slots available, these cards can be used to manage up to four normally closed or normally open
outputs, and up to three digital inputs in confi gurable mode. If more than one ADC card is used simultaneously, the dip switch
confi gurations must be di erent. Secure the card with the appropriate screws.

This card can be confi gured to control up to four outputs that can be set as normally closed or normally open and up to three digital in­puts. The card is inserted in one of two slots provided. Up to four operating modes can be selected using the two DIP switches 1 or 2.

• Electrical data

- Permitted Nominal current and voltage of NO or NC contacts: 2 A 250 Vac depending on the terminal used.

- Inputs are activated on loop closing.

• Connection of the generator

If your system uses a generator connect the ‘generator set ready’ no-potential contact to connector IN 2 on the optional ADC
card confi gured in standard or power safe mode. This automatically extends the voltage and frequency value range when power
is supplied by the generator set.

• External ESD connection

A remote emergency shutdown system (ESD) can be installed by means of the optional ADC card. Connect a normally closed
zero-potential contact to terminals IN1+ and IN1- of the ADC card.

9. TROUBLESHOOTING

The alarm messages displayed enable immediate diagnosis.
Alarms are divided into two categories:

• alarms related to the UPS external circuits, (input mains, output mains, temperature and environment).

• alarms related to the UPS internal circuits. In this case, corrective actions will be carried out by the After Sales Department.

9.1. SYSTEM ALARMS

• A02: OUT OVERLOAD

The power required by the loads is higher than the power available.
Check that the load is well balanced on the three phases by checking the measurements on the display. If necessary disconnect

any loads that do not need uninterruptible power.

Important!
The accepted overload time limit is defined in the technical specifications. When this time limit is exceeded the
loads will no longer be powered by the inverter.

• A06: VAUX OUT OF TOL

The auxiliary mains supply exceeds the acceptable tolerance values. Possible causes are:

- No voltage or frequency present or voltage and frequency outside acceptable values (see the technical specifications).

- The frequency is subject to continuous variations (typical with power supplied from an incorrectly sized GE).

• A07: OVER TEMPERATURE

The technical plant temperature is higher than the maximum value recommended.
Check the ventilation or air conditioning system in the UPS room.

• A08: MAINTEN. BYPASS

The output disconnecting switch Q6 is in position 2 (maintenance bypass). The load is therefore powered directly by mains power supply.

• A17: IMPROPER USE

This alarm does not indicate a malfunction or failure of the UPS, but an incorrect use/sizing of the system. It is activated in the event of:

- Operation for long periods at high temperatures (battery deterioration)

- High number of overloads (wrong sizing)

- Continuous battery discharging (mains not stable)

- High number of switches onto the bypass (high impulsive loads).

• A22: MAINS OUT OF TOL

The input mains is not present or not sufficient (voltage and/or frequency values incorrect with reference to the technical data); if
there is no input mains outage check that no protection devices upstream of the UPS have tripped.

Check the voltage applied and frequency values are in compliance with the values set on the mimic panel.

• A38, A39, A40, A41: EXTERNAL ALARM 1, 2, 3, 4

One of the ADC card inputs has been activated; check the status of the devices connected to this card.

• A61: PHASE ROT. FAULT

The phase cycle sequence is incorrect. In this case invert two phases of the input mains. For a UPS with separate auxiliary mains
exchange the two phases of the auxiliary mains only.

9. TROUBLESHOOTING

9.2. UPS ALARMS

• A01: BATTERY ALARM

Failure or problem on the battery circuit. Check the battery switch is closed.

• A18: OVERLOAD OFF INV

Reduce the load rate applied to the UPS and reset the alarms.

• A20: WRONG CONFIG.

Error in the configuration parameters; contact the support service.

• A30: OVERLOAD STOP

Reduce the load rate applied to the UPS and reset the alarms.

• A42:REMOTE SERVICE ALARM

This alarm indicates that a critical anomaly has occurred on the UPS. Where a maintenance contract with the Remote Monitoring option
is in place, the procedure for analysing the UPS via remote connection will be automatically activated by your service centre provider.

• A44: SERVICE CHECK

The equipment has to undergo regular checks by the support service in order to ensure optimum performance and efficiency. If
the Scheduled Inspection signal appears on the mimic panel, the equipment should be inspected by a suitably trained technician.

• A59: BATT.CIRC. OPEN

Battery switch open.

• A60: FAN FAILURE

Fault in the ventilation system; check the air inlet at the front and the air outlet at the back of the UPS are not obstructed.

9.3. PREVENTIVE MAINTENANCE

Please note that specialist regular maintenance (annually) is recommended for the MASTERYS BC to provide optimum operating
efficiency and avoid equipment downtime.

It is strongly advisable to give due consideration to any instructions to perform preventive maintenance displayed automatically
with alarm message M29 (refer to paragraph 6.2.3.1).

All operations on the equipment must only be carried out by SOCOMEC personnel or authorised support personnel.
Maintenance consists of accurate functional checks on electronic and mechanical parts with replacement of parts subject to wear

if necessary (typically batteries, fans and capacitors).

9.3.1. Batteries

The condition of the battery is fundamental to UPS operation.
Thanks to the Expert Battery System, the information relating to the battery status and conditions of use are processed in real

time and recharging and discharging procedures are selected automatically in order to optimise battery life expectancy and offer
maximum performance.

Furthermore, during the operating life of the battery, MASTERYS BC stores statistics on the conditions of use of the battery for
analysis.

Since the expected lifetime of the batteries is very much dependent on operating conditions (number of charging and discharging
cycles, load rate, temperature), a regular check by authorised personnel is recommended.

When replacing the batteries use the same type and configuration by placing them in appropriate containers to
avoid the risk of acid leakage.
Used batteries must be disposed of at authorised recycling and disposal centres.
Do not open the plastic cover of the batteries as they contain harmful substances.

42

MASTERYS BC 15-40 kVA - Ref.: IOMMASBCXX09-EN 01

9. TROUBLESHOOTING

9.3.2. Fans

The lifetime of the fans used to cool the power parts is dependent on usage and environmental conditions (temperature, dust).
Preventive replacement by an authorised technician is recommended within four years (in normal operating conditions).

When necessary fans should be replaced as per specifications by SOCOMEC.

9.3.3. Capacitors

The equipment houses electrolytic capacitors (used in the rectifier and inverter section) and filtering capacitors (used in the output
section), the lifetime of which is dependent on usage and environmental conditions.

The average expected lifetime of these components is shown below:

• Electrolytic capacitors: 5 years;

• Filtering capacitors: 7 years.
Component status is however verified during preventive maintenance.

Cable and trunk schematic

Note: The neutral is not disconnected as, even in the event of a single fault on the UPS, it never has high potential when the

mains and/or auxiliary power supplies are disconnected upstream. This is to prevent transformation of the power source to
the UPS every time there is a power failure.
Should the Neutral potential be very high due to certain error conditions or due to installations downstream (e.g. ground
fault not detected and protected, high dispersion of a phase, or the IT system), it will be necessary to install either devices
that disconnect the Neutral or alternatively a system that detects, signals and protects against high neutral/ground potential
which could lead to UPS failure.
