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.

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!

Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 12 -
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!
3.1 Rectifier
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.
