2 Description of the System

Ensuring a reliable power supply is one of many major issues when using electronic data processing and process
control systems. The main causes of many interruptions to power supply are:

 Spikes produced by switching devices on the mains distribution
 High frequency superposition caused by welding machines, fluorescent lights, photocopiers and more
 Voltage variations due to fast load variations in big inductive consumers (lifts, transformers, machinery,

etc.)

 Voltage failures due to disturbances in the mains supply
 Frequency variations caused by the use of separate power supply units

The range of disturbances extends from data corruption to memory leaks and from hardware failure to production
stoppages. Therefore, the quality of the power supply is key to the reliability of electronic data processing
equipment. The perfect solution for a secure, uninterrupted power supply for critical consumers is thus the UPS
(Uninterruptible Power Supply). The UPS:

 Generates a constant supply voltage and frequency
 Reduces mains disturbances and feedback
 Guarantees an uninterruptible power supply to connected consumers for a specified period during a

mains failure

In comparison with conventional power sources such as the mains power supply or generators*, the cutting edge
technology featured in UPS systems in the JOVYSTAR series brings the following outstanding advantages:

 Minimum mains feedback caused by active IGBT rectifiers
 Three sources of intelligence through two DSPs (Digital Signal Processor) and µC (microprocessor)
 Extended communication interfaces

 RS232/USB serial interfaces for reading UPS data (standard)
 SNMP adapter for remote monitoring, data exchange via a LAN connection (option)
 MODBUS adapter for remote monitoring, data transfer using MODBUS protocol via RS485

interface (option)

 Parallel slot for parallel redundancy systems, UPS systems communicate data with one another

via CAN bus protocol (option)

 Relay card with alarm messages for industrial remote monitoring via floating contacts (option)

*NOTE:

Operation of a UPS or other electronic consumers using a generator assumes that before installing
the complete system the planner has established whether the generator can be used in conjunction
with power electronics.
Some generators are designed such that operation with power electronics consumers is not
possible due to the additional loading with harmonics, power factor and commutation notches. In
some cases faults may occur such as voltage unbalance, a tendency to oscillate and the shutting
down of the generator. It may help to ask the generator manufacturer about this and, if necessary
change the regulator on the generator or incorporate damper windings in the generator from the
outset.

2.1 Functional description

The block diagram shows the functional design of a JOVYSTAR UPS. It comprises the component groups
"rectifier", "battery", "inverter", "static switch". The "RCB", "SBCB", "MBCB", "BCB" and "OCB" switches are used
to start and shut down the UPS as well as to switch over to the bypass. Additionally, for maintenance purposes
the battery can be disconnected from the UPS.

Block diagram of a JOVYSTAR UPS

Key to the block diagram

 Mains/Bypass → UPS supply
 RCB → Rectifier Circuit Breaker
 SBCB → Static Bypass Circuit Breaker
 MBCB → Manual Bypass Circuit Breaker
 BCB → Battery Circuit Breaker
 OCB → Output Circuit Breaker
 Output → Output for the connection of consumers

2.1.1 Rectifier

The rectifier converts the three-phase mains voltage into a regulated DC voltage to supply the inverter and charge
the batteries. The rectifier comprises the control electronics for charging the battery and IGBT components for
adjusting the power factor.

2.1.2 Inverter

The inverter converts the DC voltage from the rectifier or the battery into a stabilised AC voltage regulated by
pulse width modulation. Due to the fast regulation, the UPS generates an excellent sine -wave voltage with
extremely low distortion that even permits loads with high crest factors. The inverter output is also designed to be
short-circuit proof (electronic short-circuit protection).

2.1.3 Battery

The battery works in standby parallel operation, which means that the inverter, charger and battery are
permanently connected in parallel. To obtain the maximum lifetime of the battery it is protected by floating
operation according to DIN 41773.

2.1.4 Static bypass

Static bypass switches the load without interruption between the inverter and bypass mains input. It comprises a
thyristor bridge for the inverter and another for the bypass. For online operation the inverter output is switched to
the UPS output. In the event of an overload at the output or failure of the inverter, the UPS output continues to be
powered without interruption via the bypass.

2.1.5 Internal, manual bypass

Manual bypass is used to bypass parts of the UPS. In the event of maintenance or repair, the load is supplied
directly from the mains.

Wärtsilä JOVYSTAR COMPACT S BAX 5452 - 9 -

2.2 Operating states

2.2.1 Normal operation

Normal operation is divided into two further operating modes. For sensitive loads, online operation via the inverter
provides a stable AC voltage. For loads that are less susceptible to mains fluctuations, eco mode offers a better
efficiency rating.

Online operation

 The mains feeds the rectifier.
 The rectifier provides the DC voltage for the inverter and charges the batteries.
 The inverter supplies the load at the output with the necessary energy via the static switch.
 If there is any threat of a deep battery discharge, the system automatically switches to the static bypass

without interruption.

Online operation: load supplied via the inverter

Offline operation:

 The mains feeds the rectifier.
 The rectifier provides the DC voltage for the inverter and charges the batteries.
 The bypass supplies the load at the output with the necessary energy via the static switch.
 In the event of a mains failure the system automatically switches to the inverter without interruption.

Offline operation: load supplied via the static bypass

Wärtsilä JOVYSTAR COMPACT S BAX 5452 - 10 -

2.2.2 Inverter fault

 The mains feeds the rectifier.
 The rectifier provides the DC voltage for the inverter and charges the batteries.
 The load at the output is transferred to the bypass without interruption via the static switch.

Inverter fault: load supplied via the bypass

2.2.3 Rectifier fault

 The mains feeds the rectifier.
 The battery provides the DC voltage for the inverter (for the duration of the stored energy time).
 The inverter supplies the load at the output with the necessary energy via the static switch.
 If there is any threat of a deep battery discharge, the system automatically switches to the static bypass

without interruption.

Rectifier fault: load supplied via the inverter according to the stored energy time of the batteries

Wärtsilä JOVYSTAR COMPACT S BAX 5452 - 11 -

2.2.4 Mains failure

 The battery provides the DC voltage for the inverter (for the duration of the stored energy time).
 The inverter supplies the load at the output with the necessary energy via the static switch.
 If there is any threat of a deep battery discharge, the system automatically shuts down completely and

the load is no longer supplied with power.

Mains failure: load supplied via the inverter according to the stored energy time of the batteries

2.2.5 Manual bypass

 The load is supplied by the mains via the manual bypass.
 Any necessary maintenance or repairs to the UPS can be carried out safely.

3 Installation

Remove the packaging immediately after receiving the UPS and check the system for transport damages. The
transport company must be informed immediately after receipt of the UPS in the event of any damage caused
during transportation. If the UPS is not installed immediately it must be stored in an upright position as indicated
onthe packaging and kept in a dry, well ventilated room. If the UPS is not stored in the original packaging, it must
be protected from dust and moisture.

3.1 Handling of the UPS

The UPS is packed on a pallet. It is handled from the transport vehicle to the installation (or storage) place via a
fork lift.

The device has a heavy weight

 Avoid turnover during the transport of the UPS.
 Cabinets must always be handled in upright position.
 During loading and unloading operations, always respect the indications regarding

the device barycentre marked on the package.

Before positioning the UPS, in order to avoid risks of turnover, it’s recommended to move the system on the wood
pallet on which the UPS is fixed. Before the positioning in the final location, remove the UPS from the pallet.
To handle the UPS remove the lower front, rear and side panels and insert the forks of a fork lift. The UPS can be
handled both from the front and from the side according to the available spaces, as shown by the following

3.3 Electrical connections, cross sections, fuses

The electrical connection of the UPS unit is the task of the electrician providing the electrical installation services.
This task is not carried out by 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 all cases we recommend carrying out the installation and the electrical connections to the UPS in accordance
with local regulations and standards. Take particular care during electrical installation to ensure a clockwise
rotating phase sequence. In the event that strong electromagnetic fields are emitted, we recommend the use of
shielded cables between the UPS and the load.
In accordance with EN 62040-1, mains backfeed protection has to be provided for the UPS, preventing a current
flow from the output of the UPS back into the mains at a single fault of the system. Therefore it is necessary to
install a separator in the power supply for the bypass, which the bypass current path separates automatically in
case of a failure of the bypass mains.

ATTENTION:

Even when the mains voltage is switched off there is a dangerously high battery voltage inside the
device. All installations and connections may therefore only be carried out by qualified
electricians. Before commencing work, electricians must read this manual carefully to familiarize
themselves with the special features of this UPS unit. The UPS output still carries voltage even in
the event of a mains failure. For this reason, the installer must clearly label the outlets and
sockets on the UPS unit in accordance with EN 62040!

ATTENTION:

The input line between the mains and the UPS unit must be protected against short circuits!
The use of FI safety switches before the UPS unit is not recommended.

3.3.1 Fuses and cross sections for cable connections to the UPS

Should larger cable cross-sections be required for the installation than the maximum cross-section of the UPS
terminals, a socket or a terminal box can be installed near the UPS. From there to the UPS, a cable laying with a
smaller cross-section can be possible (better laying conditions such as installation type, cable length, ...).
