2 General Notes

It is mandatory to fulfil al works and safety requirements according to rules and instructions described herein for protect­ing the personnel working at the UPS as well as maintaining optimal duty-cycles of the UPS. All personnel installing/de­installing, starting up, and maintaining the unit must be familiar with and observe these safety regulations. Only qualified
personnel may carry out the described work with suitable and intact tools, equipment, test equipment and materials.
Important instructions are highlighted by "CAUTION:", "ATTENTION:", "NOTE:" and indented text.

CAUTION:
This symbol identifies all working and operational procedures requiring absolute compliance to avoid any
danger to personnel.

ATTENTION:
This symbol identifies all working and operational procedures requiring absolute compliance to prevent
any damage to the UPS or some of its components.

NOTE:
This symbol identifies technical requirements and additional information requiring the operator's atten­tion.

2.1 Introduction

Congratulations for chosen a UPS out of the JOVYSTAR E series! This type of static UPS incorporates the latest state of
technology in power electronics and digital signal processing. The UPS offers the optimal solution for problems in power
supply of computer-systems. UPS of this series are capable to communicate with different computer operating systems
through a standardized RS232-interface. The necessary software as well as additional hardware like SNMP-adapter or
MODBUS-adapter for remote control of the UPS is available as an option.
JOVYSTAR E UPS are real online systems (UPS-classification VFI SS 111 acc. IEC 62040-3), which prevents the at­tached loads from mains disturbances like spikes, blackouts and voltage variations. The products are screened by an
effective quality management system.
Therefore the JOVYSTAR E offers a perfect solution for various power supply problems; the reliability of the product is
our major goal since over 60 years of experience in secured power supply and techniques.
The scope of this manual is to describe the UPS and to guide the installer and the user through the correct installation.
The installer and the user will have to read this manual with care and attention and correctly carry-out the instructions
provided, especially those relevant to security according to the local standards and regulations.

NOTE:
The manufacturer declines all responsibility for damages to people or equipment deriving from non­fulfilment of the instructions mentioned in this manual.

2.2 Why Using A UPS?

The reliable power supply is one of the major issues when installing computer-based process controlling systems. The
main reasons of all disturbances are:

- Spikes, produced by switching devices in the mains distribution

- High frequency superposition caused by welding machines, fluorescence radiation, copy machines and other,

- Voltage variations, due to load variations of big inductive consumers, such as lifts, transformers, machines
and others,

- Voltage breakdown, due to disturbances in the mains,

- Frequency variations, caused by using separate power supply units.

The range of disturbances for the attached loads begins with data errors or storing-loss and extends to hardware failure
or even production blackouts. Therefore the quality of power supply is an important factor for the reliability of electronic
data processing equipment or any other sensitive loads.

Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 10 -

The best solution for a secure and safe power supply of critical loads is the use of an Uninterruptible Power Supply
(UPS). The UPS:

- Generates a constant voltage supply and frequency,

- Filters, respective suppresses mains disturbances down to a negligible value,

- Guarantees an uninterruptible power supply of the attached loads during a mains
failure for a specified period.

The UPS of the series JOVYSTAR E is a system, is being connected between the mains and the load. It always guaran­tees a secure power supply to the load over a specified period of time. In comparison to conventional power sources
(mains, motor aggregates, generators*)) the main advantages of the JOVYSTAR E series are as follows:

- Optimal quality of the output voltage,

- Prevention from spikes, superposition, transient over-voltages etc.,

- Prevention from voltage variations and mains failures,

- Prevention from frequency variations,

- Low noise,

- Small, compact design,

- Remote control facility by SNMP-Adapter or MODBUS-Adapter (option)

*) NOTE:

The operation of a UPS system or other electronic consumers at a generator assumes that the planner
was informed of whether an interworking of the generator with the power electronics is without problems
possible before the installation of the entire system.
Some generators are so laid out that an operation with power electronic consumers is not possible be­cause of the additional load with harmonics, power factor and commutation notches. In some cases can it
to troubles as tension imbalance, tendency towards oscillations and to the shut-off of the generator come.
Here it can help, to consult the generator manufacturer and to change the regulator of the generator where
appropriate or to make from the first so-called damping windings into the generator.

3 System description

UPS of this series are true on-line, double conversion UPS (classification-code VFI-SS-111); the inverter supplies the
load under normal operating conditions, whether mains is available or not (according to the battery autonomy time).

ATTENTION:
The UPS output is energized even during mains failure, therefore in compliance with the prescriptions of
EN 62040, the installer must label the outlets, plugs or lines supplied by the UPS, making the user aware
of this fact.

This true online concept guarantees great advantage to the user, as it supplies clean, continuously regulated power and
guarantees a stabilized voltage. Thanks to the double conversion principle, the load will be protected from micro­interruptions due to excessive mains variation. It prevents damage to the critical load.

OCB Output Circuit Breaker
UPS Output Output terminals (3L1, 3L2, 3L3, 3N, PE.)
Rectifier The IGBT rectifier converts the input AC-voltage into a regulated DC-voltage supply-

ing the inverter and charging the batteries.

Inverter The inverter converts the DC-voltage delivered by the rectifier or by the battery into

an AC-voltage, regulated by Pulse-Width-Modulation. The output of the inverter is
short circuit proof by electronic short-circuit-protection.

Static Switch The static bypass consists of a thyristor-switch. It switches the mains over to the UPS

output. During normal operation the inverter output is switched to the UPS output
while the bypass is blocked. During overload at the UPS output or an inverter failure
the attached loads will be supplied immediately by the bypass.

Manual Bypass The manual bypass feeds the load in case of maintenance or disturbances of the

UPS. The manual bypass is to be used only by qualified personnel under considera­tion of the described instructions in this manual!

ATTENTION:

A handling error of the internal or (if applicable) any external manual bypass could lead to a total
blackout at the output of the UPS!

It converts the three phase voltage of the AC mains into continuous DC voltage. It uses a three phase fully-controlled
IGBT bridge with a low harmonic absorption. The control electronics uses a 32 bit uP of latest generation that allows to
reduce the distortion of the current absorbed by mains (THDi) to less than 5%. This ensures that the rectifier does not
distort the supply mains, with regard to the other loads; it also avoids unlikely overheating of the cables due to the har­monics circulation.
The rectifier is so sized as to supply the inverter at full load and the battery at the maximum charging current.

3.2 Inverter

It converts the direct voltage coming from the rectifier or from the DC battery into alternating AC voltage stabilized in
amplitude and frequency. The inverter uses IGBT technology with a high changeover frequency of approximately 10
KHz. The control electronics uses a 32 Bit uP of latest generation that, thanks to its Processing capability, generates an
excellent output sine-wave.
Moreover, the fully digitized control of the output sine-wave allows to achieve high performances, among which a very
low voltage distortion even in presence of loads with high crest factor currents.

3.3 Battery and Battery Charger

The battery is installed outside the UPS. It is generally housed in an external battery cabinet. The battery charger logic is

completely integrated in the rectifier’s control electronics. The battery is charged, according to the DIN 41773 Standard,

every time it has been partially or completely discharged. When its full capacity is restored, it is kept floating so as to
compensate for any autodischarge.

3.4 Static Bypass

It serves to transfer the load between INVERTER and MAINS, and vice-versa, without interruption, and uses SCR’s as
power commutation elements.

3.5 Manual Bypass

It provides a solution of bypassing the UPS by itself, supplying the load directly by the mains in case of maintenance or
serious failure.

ATTENTION:

The sequence of switching to bypass must be carried out with respect to the procedure indicated on the

UPS and in the chapter “Operating the UPS”. The manufacturer cannot accept responsibility for damages

arising from incorrect operation.

3.6 Front Panel

The front panel of the UPS, consists of a double row alphanumeric display including 5 function keys, allows the complete
monitoring of the UPS status. A mimic diagram helps to understand the operating status of the UPS. For more infor­mation see the chapter “Operation”.

3.7 Operating status

The following paragraphs show all the possible operating status of the UPS.

3.7.1 Normal operation

The inverter is supplied by the rectifier, which also charges the battery. The load is supplied by the inverter output direct­ly, via the inverter static switch SSI. The load is in the best conditions in terms of supply Protection.

3.7.2 Load supplied by bypass due to inverter fault

In case of inverter fault, the load is transferred to bypass, emergency line, through the static bypass switch SSB; the
transfer is carried out without interruption.

3.7.3 Rectifier failure or mains failure

The inverter is supplied by the battery for the stated autonomy time; the load, through the inverter static switch SSI, is
supplied directly by the inverter output.

Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 14 -

3.7.4 Internal Manual bypass

The load is supplied by the input mains through the manual bypass. The operator can work in safety on the UPS to carry
out maintenance or repairing operations.

4 Installation

4.1 Reception of the UPS

After reception of the UPS, unpack immediately and carry-out an accurate visual check for any transport-damages.

IMPORTANT:

In case of objections relating to damage incurred during transport these must be immediately notified to
the transportation company after reception of the product.
When the UPS is not installed immediately it must be stored carefully in vertical position, as indicated on
the packing and conserved in a dry and sheltered room in its box so that it is protected from dust.

4.2 Transport

Before positioning the UPS, in order to avoid risks of turnover, it is recommended to move the system only while mount­ed on the wood pallet. Before the positioning in the final location, remove the pallet from the UPS. The UPS can be lifted
and handled using a pallet truck or a forklift.

ACHTUNG:
Paying attention to the center of gravity of the UPS! The brackets must be long sufficient and far enough
from each other stand.

i

Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 16 -

4.3 Setting up

The UPS must be installed in a clean and dry room, preferably not dusty. The user must ensure a proper air conditioning
for cooling the equipment. If the UPS contains the batteries internally the air exchange with the external ambient must
comply with EN 62040, annex N.
Pay attention, that through the weight of the UPS and the batteries the maximum floor loading will not exeeded. You find
informations to the weights and the measurements in the technical data. In addition the site must fulfil the following re­quests:

- The UPS may be installed only in dry rooms.

- None caustic or acid steam may escape.

- The device supply air temperature may be maximally 40°C.

- Whem batteries are supplied to this UPS installation, the air exchange for these batteries with the external sur­roundings must according to EN 62040 appendix N.

- The vent holes at the device must not be covered by construction measures or other factors.

- The device is to be protected against direct solar radiation and action of other heat springs.

- The wall- and ceiling-distances as well as the recommended air flow volume (see also technical data) are com­plying for an optimum cooling of the UPS. An overheating of the system is thus avoided.

4.4 Electrical Connections

ATTENTION:

Even with switched off mains there is a dangerous high battery voltage inside the UPS. All installations
and connections may only be carried out by qualified technicians. The technician must familiarize himself
with the special features of this UPS by carefully reading and understanding this manual.
Please observe the special notices for connections of a parallel-system.

The work for electrical connection is a part of an electrician who installs the whole electric installation. It is not part of the
UPS manufacturer. For this reason, the following recommendations are only an indication, as the UPS manufacturer is
not responsible for the electrical installation.
In any case we recommend carrying out the installation and the electrical connections to the UPS in accordance to the
local rules and standards.
During the electrical installation make sure a right phase rotation at the three-phase input terminals of the UPS.
In case of strong electromagnetic fields emission it is recommended to use a shielded cable between UPS and the load.
In accordance to EN 62040-1 a mains-feed-back protection has to be provided for the UPS, preventing a current flow
from the output of the UPS back into mains at a single fault of the system. Therefore both the lines for the main input and
the bypass lines have to be fed via a contactor, which opens in case of a mains blackout.
For improving the quality of connection of the UPS flexible cables are recommended. A cable clamp must be provided by
the end-user directly at the structure of the frame or right below the UPS cabinet.
The wire diameters given in the below table refer to a distance of 20m between load and UPS. These values are recom­mendations only. They have to be recalculated particularly considering the actual environment conditions!
At larger distances the permissible voltage drop, the environmental temperature and the cable grounding have to be
dimensioned according to VDE or local rules. Local rules for the protection ground-wires have to be considered.
The suitable diameters of cables and the sizes of the fuses are to be designed with regard to the environmental tempera­ture, the cable grouping and length of cables according to the local rules and according to VDE.
The terminals are positioned at the lower part of the UPS and they can be accessed by opening the front door.

ATTENTION:
The input lines to the UPS must be fuse protected. The use of residual current switches in the line sup­plying the UPS is not recommended. The leakage current due to the RFI filters is rather high and it can
cause spurious tripping of the protection device.
If any residual-current-switch has to be used, it is recommended the use of a device with short-time de­lay for differential currents higher than 300mA.

The following table represents a summary about the current carrying capacity acc. DIN VDE- and EN-rules at an envi­ronmental temperature of 30°C. The necessary diameters of cable and the sizes of the fuses are to be designed with
regard to the environmental temperature, the cable grouping and length of cables according to the local rules and ac­cording to VDE.

NOTE:

The suitable cable cross-sections and sizes of the fuses must be determined considering the ambient
temperature, the cable grouping and the cable lengths according to the local rules and the local regula­tions of the electrician or planner. Since the manufacturer of the installation does not know the local
factors, a liability of the manufacturer is impossible concerning the electrical installation.

The given values of cable diameters do not reflect the required diameters of the protective earth cable! They
have to be calculated in accordance to VDE 0100 part 540 or an applicable local rule.

4.4.3 Battery connection

IMPORTANT:

Prior to connecting to any external battery the standard EN62040, par. 4.5 must be observed. For ensur­ing the maximum lifetime for the battery, according to the statements of the battery manufacturer, the
operating temperature of the battery must be held between 20°C and 25°C. Otherwise the lifetime will be
reduced drastically, even in the case that the battery can work at temperatures of up to 40°C. For pre­venting of forming explosive gases of hydrogen/oxygen mixtures a suitable air-ventilation has to be in­stalled according to EN62040, Annex N).

It is recommended install the battery, only if the UPS will be able to recharge it. Consider that a battery which is not being
charged within 2-3 months can be irreversibly damaged.

IMPORTANT:

A battery must be maintained periodically. Observe the instruction manual of the battery manufacturer. It
will be found in the annex of this manual.

WARNING:

After switching off the UPS, please open the battery circuit breakers and, if present, the fuses for the
battery symmetry monitoring resp. the charging circuit monitoring fuses. In other case, the power supply
consume a little current from the Battery. After a couple of hours, the battery will be deep discharged.

IMPORTANT:

If the batteries are not supplied in complete battery cabinets, extra fuses or circuit breakers are to be
planned for the battery. Alternatively a BAU (Battery adapter unit) is available as an option.

6 Options

6.1 Parallel redundant system

The parallel system can consist of up to 5+1 (redundant parallel) or 6 (power parallel) units. Each unit is equipped with
an additional parallel-redundant kit for controlling the parallel related functions.
In addition to the standard functions such as uninterruptible power supply to the load, total power control and protection
of the load from mains distortion, the parallel redundant system guarantees an uninterrupted power supply even in case
of an internal failure in one of the UPS units.
The current sharing regulation circuitry controls the currents of the “n” units and therefore balances the currents to better
than 10%, under all load conditions. The load supplied by the inverters in parallel may have an instantaneous overload
up to “n x 200%” of the nominal load of the single unit. In case of a failure in one unit, the load is still supplied by the
other units. The load transferred to the static bypass only in case of failure of more than one unit.

NOTE:

For obtaining a balanced load-sharing between the single UPS-systems, it is mandatory to keep the input­(i.e. Bypass-) lines as well as the output lines of the single units with the same length to each other and to
the distribution. In cases of extremely short length of wires, and also in cases of a very high diameter of the
cables, it is possible, that the load sharing between the single units is weak. In these cases an adjustment
at the final operating place of the units will be necessary.

6.1.1 Additional hardware

To transform “n” standard units into a parallel redundant system the following additional hardware is required:

“n” PCB SLOT-PAR (PB214)
“n” CANBUS-Cable (SUB-D9, 1:1)

The outputs of the “n” units must be connected in parallel to the load bus bar. “n” is the number of the UPS systems in

parallel.

NOTE:

The standard units must be special programmed to work in parallel redundant. Please contact our service
department!

6.1.2 System layouts

The parallel redundant system has better static and dynamic performances in comparison to a single unit since, owing to
the redundancy, the total amount of power available his higher than the nominal load of the overall system.

Overload

The overload limit of a parallel redundant system depends on the number of the units which are connected to the load:
Imax = n x In, where “n” = number of the units, “In” = nominal current of each unit.
If the load exceeds this limit the thermal image protection is activated and, after a certain time the load is transferred to
bypass (if available).

Short circuit

In case of a short circuit at system output the load is transferred to bypass (if it is available).

6.2 Battery symmetry monitoring

The correct charging of the batteries are monitored by the PCB P0037401. In case of more than one ropes, each rope
must have is own monitoring-module. The following faults will be detected:

- Asymmetrical voltage between the battery blocks in a row (e.g. a defective battery cell within one block)

- In case of using voltage sensors connected directly to the output terminals of the charger, am open line as well as a
too high impedance will be detected.
These problems might arise as a matter of corrosive contacts defective battery fuses or weak contacts.
In case of a detected fault, the red LED V9 on the PCB will light up. In addition the UPS will signalize „BCB open“ due to
the fact that a relay contact is connected in a row together with the monitoring contact of the BCB.
After fixing the fault the monitoring circuit has to be reset by pushing the reset button S1 on the PCB.

Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 47 -

NOTE:

When starting up the UPS this PCB has also to be reset when a message for closing the BCB appears.

CAUTION:

Even at switched off input mains, a dangerous high voltage is still present inside the UPS!

The interconnection of the battery symmetry monitoring PCB is shown in a wiring diagram in annex.

6.3 Relay PCB

6.5 Shut-down software

A controlled shutdown of computer-systems which are being attached to the UPS is possible by using a shutdown­software. Using this option either the relay-PCB, a SNMP-adaptor or a direct connection between the PC and the serial
interface is necessary. The shutdown software is available for various operating systems. Please contact our sales de­partment for further details. Please provide information about the operating system, the type and amount of PC’s being
used.

6.6 Temperature compensation

With this option the charging voltage for the battery can be regulated by means of the temperature. A sensor is placed
adjacent to the battery and connected to the rectifier of the UPS. The battery charging voltage gets reduced about –
1mV/°C per cell, e.g. a Ups with a 192 cell battery will therefore reduce the charging voltage of about -192mV/°C. The
minus sign indicates the declination of the battery charging voltage at rising temperature.
The interconnection of the temperature sensor is shown in diagram X0013800.VP3 in annex.

6.7 MODBUS-Adapter

The application of the Modbus-Adapter is described in the operating manual BAX 2408.

the skin, eyes and when inhaled.
The applicable protective measures must be complied with in accordance with the safety regulations of
VDE 0510, Part 2.

When using an open battery the electrolytic level must be inspected. If it has reached its lower level, the battery must be
refilled with distilled water according to DIN 43530 part 4. The battery must be kept clean and dry in order to prevent
leakage current. Plastic-components of the battery, especially the cell compartments, may only be cleaned with pure
water. Every three months the measuring and logging shall include the following:

- Battery voltage, if possible the voltage of each cell / block

- (If applicable)The electrolyte temperature of the block batteries.

If applicable, the following items must be checked and logged every year according to DIN 43539 part 1 and special
inspections are to done according to VDE 0108:

- Density of electrolyte

- Voltage of all cells / blocks of battery

- Quality of bolted fastening

Additional checks with automatic test equipment are not permitted, except the written approval of the battery manufac­turer.

NOTE:

In case the battery voltage is out of tolerance and/or charging is not successful, the Service­Department should be contacted.

instructions must be followed. Either the battery manufacturer or our service department shall be con­sulted in this case. In certain circumstances the charger of the UPS must be readjusted to the battery.

8 Status messages and alarms

Successful troubleshooting of all but the most obvious failures (e.g. blown fuses, defective fan, etc.) requires an in-depth
technical background in electronics technology. Knowledge about electrical engineering is also mandatory.
Troubleshooting requires the use of a dual trade (or two channel) oscilloscope, a digital multimeter, a phase rotation
meter and other electronic instruments. Only qualified personnel may attempt troubleshooting.
This chapter includes a first level fault description starting from the UPS alarms and suggests how to check the unit to
solve the problems. This description assumes that all the connections inside the unit are correct. Connectors, power
cables, signals and so on should be checked prior to start to follow the troubleshooting. The intervention consists of to
substitute the components of the UPS without trying to repair them.
