 1. SAFETY STANDARDS

1.1. IMPORTANT
• This document provides important instructions for the safe use, movement and connection of the MASTERYS BC uninterrupt-
ible power system (UPS).
• SOCOMEC retains the full and exclusive ownership rights over this document. Only a personal right to use the document for
the application indicated by SOCOMEC is granted to the recipient of the document. The reproduction, modification, 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 specification. SOCOMEC reserves the right to make any changes to information provided without prior
notice.
• The unit must only be installed and activated by qualified 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 first 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 off 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 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.

 2. UNPACKING AND INSTALLATION OF THE UNIT

The packaging guarantees the stability of the UPS during shipping and physical transfer. Carry the packaged unit as close as possible
to the installation site.

When moving the unit on even slightly sloping surfaces, use the blocking equipment and braking devices to ensure
that the unit does not fall over.

2.1. SHIPPING AND MOVING

• The UPS must remain in a vertical position during all shipping and moving operations.
• The unit has wheels that can be used to move it for short distances.
• Ensure the floor is strong enough to support the weight of the UPS and battery cabinet, if used.

Avoid pressing on the front panels when moving the unit.

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.

CAUTION IF DAMAGED
NON-SPILLABLE BATTERIES
If packaging is crushed, ripped or open such that the inner contents are revealed, the equipment should be kept in
an isolated area and inspected by a qualified person. If the packaging cannot be shipped the contents should be
collected promptly, kept apart, and the sender or recipient should be contacted.

All packaging must be recycled in compliance with existing legislation in the country where the system is installed.

2.2. ENVIRONMENTAL REQUIREMENTS

• The recommended operating temperature, humidity and altitude values are listed in the technical specifications table (see chapter 10).
Cooling systems may be required to maintain these values.
• Avoid dusty environments or areas where there is dust from conductive or corrosive materials (e.g. metal dust or chemical solutions).
• The UPS is not designed for outdoor use.
• Do not expose the UPS to direct sunlight or sources of excessive heat.
• A space of at least 40 cm must be left at the back for adequate ventilation (see figure 2.2-1).
• The UPS switches are accessed from the front; however, a space of at least 1.5 metres should be left at the front of the UPS for
maintenance purposes. It is also advisable to ensure that the cable connections are sufficiently long and flexible so that the unit
can be extracted during maintenance (see figure 2.2-2).
• If it is not possible to leave sufficient space at the front, adequate access must be ensured from both sides.

 2. UNPACKING AND INSTALLATION OF THE UNIT

2.3. ELECTRICAL REQUIREMENTS

The installation and system must comply with national plant regulations.
The electrical distribution panel must have a protection and sectioning system installed for the input mains and the auxiliary mains.
If a differential switch is installed on the mains power switch (optional), it must be inserted upstream from the distribution panel.
The table below shows the size of the input protection devices recommended for correct installation.

1. Magneto-thermal switch recommended: four poles with intervention threshold ≥10 In (curve C). It is necessary to use a D curve selective
breaker if an optional external transformer is used.
2. In systems with two or more UPSs operating in a redundant or power parallel configuration.
3. Determined by the size of the terminals.
4. Protection on the external battery cabinet (preferably 2 bipolar protection devices or one quadripolar).
5. Caution! Use selective type differentials. 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 differential protec-
tion. 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
definitive load, so as to prevent the sudden activation of the above switches.
6. Use 2500 aR for a battery cabinet with capacity exceeding 90 A.

This unit has been designed for connection to an ordinary AC power supply, i.e. with transient voltage in overvol-
tage II category. Should it be necessary to connect the UPS to a higher overvoltage category (e.g. at the beginning
of the installation, or to primary distribution circuits), or should the UPS risk being exposed to higher transient
overvoltages, adequate external protection devices must be installed.

GENSET must support load variations from 0 to 100%.

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.

Downloaded from www.Manualslib.com manuals search engine
 2. UNPACKING AND INSTALLATION OF THE UNIT

2.3.1. 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 as close as possible to the UPS. 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.
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 that could lead to UPS failure.

NOTE
For equipment with separate Emergency Mains, it must be possible to make the neutral of the Emergency Mains
line electrically common with the neutral of the main input feed line.

2.4. INSTALLATION PROCEDURES AND INSTRUCTIONS

The procedure below should be followed closely for correct installation:
2.4-1 Set switches Q2/Q4, Q3, Q5 to position 0, open the switches of any external battery cabinets.

Switch off the UPS, remove the power, open the switches of any external battery cabinets, isolate the system and
wait for 5 minutes before working on the terminal board or any internal UPS parts.

2.4-2 Open the terminal board protection panel at the back of the UPS by removing the four fastening screws A.

The terminal board shown is the most complete version including all options. On basic models or models with inter-
nal batteries the terminal board has fewer terminals. Refer to the names of each terminal to identify it during
connection. After connection secure the cables with bands C (figure 2.4-3) to couplings B as shown in the figure 2.4-6.

2.4-3 Connect the ground lead to the terminal with the corresponding symbol. Connect the input cables to the terminals labelled
MAINS SUPPLY L1, L2, L3, N (observing the phase cycle direction).

2.7. UPS PARALLEL CONFIGURATION

2.7.1. General
Parallel connection enhances UPS system reliability, performance and power.
All MASTERYS BC 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.

ENGLISH
UPS modules for parallel operation are identical to standard UPS modules, as a result safety, shipping and installation recommen-
dations in chapters 1 and 2 also apply.

2.7.2. Installation
UPS units operating in parallel are interconnected using control cables B (fig. 2.7.3-1) and are configured differently depending on
the position they are assigned.
For this reason the units have a position label C (Fig. 2.8-1):
• 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 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.

2.7.3. Power connections

• The power supply to each unit must be protected as indicated in the table in paragraph 2.3.
• The cross section and length of the input and output cables must be identical for all the 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 (Fig. 2.7.3-1).
• The cables from the UPS module to switch F must be of the same length (max. 7.5 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
(see fig. 2.7.3-1, 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.

2.8. CONTROL CONNECTIONS

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 standard parallel setups 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 2.8-1, leaving the connector(s) unconnected (in the central UPS one incoming and one

 2. UNPACKING AND INSTALLATION OF THE UNIT

2.9. EXTERNAL BATTERY CABINET CONNECTION

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 (figure 2.9-1).
• Connect the cables between the UPS terminals and the battery cabinet terminals, strictly observing the polarity of each individual
string (figure 2.9-1) and the cross-sections indicated in table 2.3.

Use double insulated cables or the cables supplied with the unit to connect the UPS to the battery cabinet.

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

• Replace the terminal board protection.

If using cabinets not supplied by the UPS manufacturers, it is the installer’s responsibility to check electrical compa-
tibility and the 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, capa-
city, 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

ENGLISH
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 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 perfor-
med by service personnel without having to disconnect the power supply to the load.

 3. MODES OF OPERATION

3.4. OPERATION WITH EXTERNAL MANUAL BYPASS (optional)

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 perfor-
med by service personnel without having to disconnect the power supply to the load.

 3. ACESS TO CONTROLS

4.2. SWITCH FUNCTIONS FOR THE 60-80 kVA RANGE

With common mains input:
• Input switch Q2:
- The input switch provides the primary power supply to the UPS.
- In normal operating conditions this should be in position 1 ON.
- The position 0 OFF will cause the batteries to discharge.
With separate mains inputs:
• Input switch Q4:
- The switch provides the power supply to the automatic bypass line.
- In normal operating conditions this should be in position 1 ON.
WARNING!
in this configuration the mains power supply to the rectifier cannot be isolated inside the UPS, only via external
protection devices.
• Output switches Q3 and Q5:
- These are used to manage UPS output.
Q3 connects the UPS output to the inverter (continuous power supply). Q5 connects the output directly to the auxiliary mains
input (manual bypass).
- Positions Q3 closed (1) and Q5 open (0): this is the position for normal operation of the UPS for a continuous power supply to
the load.
- Position MANUAL BYPASS Q3 open (0) and Q5 closed (1): this position should only be selected for standard or special main-
tenance operations (manual bypass); the load is connected directly to the auxiliary mains.
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.
Refer to the relevant procedure described below on how to activate the bypass; see chapter 6.
- Positions OFF Q3 open (0) and Q5 closed (0): this completely isolates the UPS output by removing the voltage from the appli-
cations in any operating conditions.
It is used for the emergency shutdown of the system (internal ESD).

 6. OPERATING PROCEDURES

6.1.4. Switching onto manual bypass

Switching onto the 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 EFFICIENCY MODE command from the COMMANDS > 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

ENGLISH
auxiliary mains is not suitable for the load).
• Set switch Q5 to position 1 (bypass on load) and then put switch Q3 to position 0 (inverter in output OFF).
• Set the battery switches to position 0 (battery circuit open).
• Open the switch Q4/Q2.
• In the event of a separate input mains disconnect the UPS primary input mains.

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

6.1.5. Return to normal mode

• Set switch Q4/Q2 to position 1 (input mains ON).
• Set 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 EFFICIENCY MODE command from the COMMANDS > IMMEDIATE COMMANDS menu.
• Set switch Q3 to position 1 (inverter in output ON).
• Check that alarm A06 is not present (if the alarm is present resolve the problem before continuing).
• Set switch Q5 to position 0.

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

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

6.1.6. Emergency shutdown

Should it be necessary to interrupt the continuous power supply provided by the UPS quickly (emergency shutdown), this can be
done by putting switch Q3 to position 0 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 Q3.
If the UPS is operating from the manual bypass (Q5 in position 1) with mains present, the emergency shutdown
does not interrupt the power supply to the load. In emergency conditions all the power supplies upstream of the
UPS must be disconnected.

 8. 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.

8.1. SYSTEM ALARMS

ENGLISH
• 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 Q3 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.

 8. TROUBLESHOOTING

8.2. 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.

8.3. 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 chapter 5).
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).

8.3.1. 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.

 8. TROUBLESHOOTING

8.3.2. 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.

8.3.3. Capacitors

ENGLISH
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 life of these components is shown below:
• Electrolytic capacitors: 5 years;
• Filtering capacitors: 7 years.
Component status is however verified during preventive maintenance.

 9. ELECTRICAL OPTIONS

9.1. INSULATION CONTROLLER

This device continually checks transformer insulation, displaying an alarm message on the mimic panel.

9.2. EXTERNAL MAINTENANCE BYPASS

This device will electrically exclude and isolate the UPS (e.g. for maintenance operations) without interrupting the power supplied
to the load (see paragraph 3.4).

9.3. ACS PCB

Synchronises UPS output with an external power source (another UPS, even of a different brand, generator or transformer).

9.4. SEPARATE AUXILIARY POWER SUPPLY

This allows the use of an auxiliary energy source other than the primary mains power supply in the event of outage.

9.5. EXTERNAL BACKFEED PROTECTION

External devices can be installed to protect against the backfeed of dangerous currents, both on the MAINS SUPPLY and on the
AUX MAINS SUPPLY. These devices are controlled by the BKF PCB shown in figure 9.5-1.
The BKF PCB is installed in the position shown in figure 9.5-2.
Refer to the following paragraphs for details on electrical connections and activating the chosen protection.

WARNING
The neutral connections on the UPS input or output are identical. Consequently there is no risk of high potential
when the input power supply is absent.
However, depending on the type of system connected to the output or in some failure conditions (earth leakage,
significant phase dispersion or in the case of non-insulated neutral systems), high potential can be detected. It
would therefore be necessary to install either adequate neutral switching or a protection system.
