2.1 Description Of The System
Congratulations for chosen a UPS out of the JOVYSTAR 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-Agent, MODEM etc. for remote
control of the UPS is available as an option.
JOVYSTAR UPS are real online systems (UPS-classification VFI SS 111 acc. IEC 62040-3), which prevents the at-
tached loads from mains disturbances like spikes, blackouts and voltage variations. The products are screened by an
effective quality management system. Therefore the JOVYSTAR offers a perfect solution for various power supply prob-
lems.
The reliability of the product is our major goal since over 60 years of experience in secured power supply and tech-
niques.
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.
i
NOTE:
The manufacturer declines all responsibility for damages to people or equipment deriving from non-
fulfilment 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.
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 is a system, is being connected between the mains and the load. It always guaran-
tees 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 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,

2.3 General Description of A UPS
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 micro-
interruptions due to excessive mains variation. It prevents damage to the critical load.

- Rectifier The rectifier converts the input AC-voltage into a regulated DC-voltage supplying 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.
With an output current> 100% of rated current or a failure of the inverter the power
supply is switched without interruption on the bypass through the internal static
switch.
- 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 out-
put 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 considera-
tion 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!
2.3.1 Rectifier
The rectifier converts the three phase voltage of the mains into a DC voltage. It uses a 6 pulse fully-controlled thyristors
bridge. The rectifier is designed to supply both the inverter at full load and the battery at the maximum recharge current.
The system offers very low ripple content during the charging cycle.
2.3.1.1 Twelve-Pulse Rectifier (Option)
The twelve-pulse technology is used to reduce the distortion of the current absorbed from the mains (THD) to a value
<12%. This ensures that the rectifier does not distort the mains above these limits. A higher distortion could be an issue
for other loads. It also avoids overloading of cables due to the harmonics circulation. This system is highly recommend-
ed for high power equipment, where the current distortion caused by the rectifier might affect other loads connected to
the mains.
The twelve-pulse rectifier can be provided both, with or without galvanic isolation. It is built by either a choke together
with an isolating transformer or by a transformer with two secondary windings.
twelve-pulse rectifier without galvanic isolation twelve-pulse rectifier with galvanic isolation
2.3.2 Inverter
It converts the DC-voltage delivered by the rectifier or battery into alternating, stabilized voltage. The control circuitry is
completely digitally. Due to the fast regulation it generates an excellent output sine-wave, which has a very low distortion
even in presence of loads having high crest factor currents.

2.3.3 Battery and Battery Charger
The battery is placed inside the UPS up to 32KVA in case of small autonomy times. It is placed in an external battery
cabinet for higher UPS ratings and/or autonomy times. The control-electronic for the rectifier includes the circuits for the
battery charger too. The battery operates in stand-by parallel operation to the rectifier. For obtaining the maximum life-
time of the battery it is charged in trickle-mode according to DIN 41773.
2.3.4 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.
2.3.5 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.
2.3.6 Front Panel
The front panel of the UPS, consists of a double row alphanumeric display including 5 function keys, allows the com-
plete monitoring of the UPS status. The mimic diagram helps to understand the operating status of the UPS. For more
information see the chapter “Operation”.

3 Installation
3.1 Reception
After reception of the UPS, unpack immediately and carry-out an accurate visual check for any transport-damages.
i
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.
3.2 Transport
Before positioning the UPS, in order to avoid risks of turnover, it is recommended to move the system only while mount-
ed 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.
3.2.1 Setting Up and Installation
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.

3.3 Electrical Connection
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 technical data refer to a distance of 50m between load and UPS. These values are recom-
mendations 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 temper-
ature, 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 sup-
plying 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 envi-
ronmental temperature of 30°C.
The necessary diameters of cable and the sizes of the fuses are to be designed with regard to the environmental tem-
perature, the cable grouping and length of cables according to the local rules and according to VDE.
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.

ATTENTION:
For ensuring the selectivity all fuses should have the utilization category “gL”. In this case selectivity is
existent for fuses up to 16AgL. When using higher fuse ratings or automatic cutout a selectivity calcula-
tion must be carried out according to the local requirements. For the battery fuses a suitable breaking
capability must be ensured.

3.3.2 External Battery
i
IMPORTANT:
Prior to connecting to any external battery the standard EN62040, par. 4.5 must be observed. For ensur-
ing 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 pre-
venting 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, either internal or external, 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.
i
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 remove the Battery Fuses. In other case, the power supply consume
a little current from the Battery. After a couple of hour, the battery is damaged.
Please contact our Service department after a failure. Jovyatlas does not take over any liability for late
error reports.
