2 Description of the system
Ensuring a reliable po er supply is one of many major issues hen using electronic data processing
and process control systems. The main causes of many interruptions to po er supply are:
Spikes produced by s itching devices on the mains distribution
High frequency superposition caused by elding 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 po er supply units
The range of disturbances extends from data corruption to memory leaks and from hard are failure to
production stoppages. Therefore, the quality of the po er supply is key to the reliability of electronic
data processing equipment. The perfect solution for a secure, uninterrupted po er supply for critical
consumers is thus the UPS (Uninterruptible Po er Supply). The UPS:
Generates a constant supply voltage and frequency
Reduces mains disturbances and feedback
Guarantees an uninterruptible po er supply to connected consumers for a specified period
during a mains failure
In comparison ith conventional po er sources such as the mains po er supply or generators*, the
cutting edge technology featured in UPS systems in the JOVYCUBE series brings the follo ing
outstanding advantages:
Minimum mains feedback caused by active IGBT rectifiers
Extended communication interfaces
• Serial port (USB) to read out the alarm history and for soft are updates
• SNMP adapter for remote monitoring, data exchange via a LAN connection
• MODBUS adapter for remote monitoring, data transfer using MODBUS protocol via
RS485 interface
• Enhanced capacity and redundancy based on installation of additional modules
• Relay card ith alarm messages for industrial remote monitoring via floating contacts
NOTE:
Operation of a UPS or other electronic consumers using a generator assumes that before
installing the complete system the planner has established hether the generator can be
used in conjunction ith po er electronics.
Some generators are designed such that operation ith po er electronics consumers is
not possible due to the additional loading ith harmonics, po er factor and commutation
notches. In some cases faults may occur such as voltage unbalance, a tendency to
oscillate and the shutting do n 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 indings in the generator from the outset.

2.1 Functional description
The block diagram sho s the functional design of a JOVYCUBE UPS. It normally comprises several
parallel s itched single modules. The "ICB", "MBCB", "BCB" and "OCB" s itches are used to start and
shut do n the UPS as ell as to s itch over to the bypass. Additionally, for maintenance purposes the
battery can be disconnected from the UPS. The dra ing includes the optional static bypass (smart
bypass).

2.1.1 UPS module
One UPS module on its o n in fact provides all the functionality of a conventional UPS system, including
a rectifier, inverter and battery charger.
The main benefit of these UPS modules lies in their hot-pluggable and hot-s ap capability.
This means that in live operation you can plug additional modules into the UPS cabinet, provided there
are free slots available, and remove modules from it, provided the po er supply of the remained
modules is sufficient.
2‑2 The block diagram gives an description of the topology and operation of a 20kVA module

WÄRTSILÄ JOVYCUBE 160 BA 5157 - 9 -
2.1.2 Static bypass module
Depending on the operating mode, the static bypass module (SBP module for short) improves the
consumers' supply reliability and/or saves energy. Thanks to the 200 kVA/kW output and a short-circuit
current of max. 2,900 A/20 ms per module and phase, fuse triggering due tom short circuits or load
surges presents no problem.
There are t o operating modes available. These are set either using the s itch on the module or in the
soft are.
In VFI mode (voltage and frequency independent), load is supplied through the UPS. The static s itch
only becomes active in the event of a malfunction, of overload or if there is a short circuit. Load is applied
to the SBP module ithin 5 ms.
In ECO mode, load is supplied permanently via the SBP module. As mentioned above, this offers the
benefit of reduced energy consumption. In the event of failures and/or mains grid irregularities, battery
mode is engaged immediately, thus ensuring critical load.
2
-
1 Topology with shared input
2
-
2 Topology with separate input
As the diagrams sho , the module is connected in parallel to the 20 kVA UPS modules.
The module's dimensions correspond to those of a UPS module. The SBP can therefore be retrofitted
into an existing system ithout difficulties provided there is sufficient space and shared input is ensured.
2.1.3 UPS system
A UPS system normally comprises several UPS modules interconnected inside a UPS cabinet by ay
of a rail system hich together supply the po er needed by the connected consumers.
If you install an additional UPS module in such a UPS system you ill be sure of maintaining the best
possible safe supply to connected consumers, as the redundant UPS module maintains the po er
supply in the event of a technical fault in one of the primary modules.
In such a case you can easily and conveniently replace the faulty UPS module ith a ne one hile the
other modules continue supplying the connected consumers.
2.1.4 Battery
The battery orks in standby parallel operation, hich 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.
2.1.5 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.

2.2 Operating states
NOTE:
The block diagrams include the optional SBP static bypass. It is integrated into the system depending
on the UPS design.
2.2.1 Normal operation
In normal operation, all the installed UPS modules supply the connected consumers, ith the po er
demand being spread equally across all the UPS modules.
Online operation
The mains feeds the rectifiers.
The rectifiers provide the DC voltage for the inverter and charge the battery.
The inverters supply the load at the output ith the necessary energy.
2‑3 Online operation: load supplied via the inverter
2.2.2 Module error
The mains feeds the rectifiers.
The rectifiers provide the DC voltage for the inverter and charge the batteries.
In the event of a module error, the module concerned is shut do n and the load is distributed
across the remaining modules, provided enough reserve is available. If not enough reserve as
available, the UPS ould s itch to overload mode and so supply to the consumers ould no
longer be assured. For that reason, e recommend running a redundant 20kVA module in
parallel.
2‑4 Module error: Load supplied via the remaining UPS modules

WÄRTSILÄ JOVYCUBE 160 BA 5157 - 11 -
2.2.3 Mains failure
The battery provides the DC voltage for the inverters (for the duration of the stored energy time).
The inverter supplies the load at the output ith the necessary energy.
If there is any threat of a deep battery discharge, the system automatically shuts do n
completely and the load is no longer supplied ith po er.
Note:
In case of failure of one phase at the input, the load is proportionately supplied of the t o
remaining phases and from the battery until it is discharged.
2‑5 Mains failure: load supplied via the inverter according to the stored energy time of the
batteries
2.2.4 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.
2‑6 Manual bypass Load supplied via the manual bypass
i

- 12 - BA 5157 WÄRTSILÄ JOVYCUBE 160
2.2.5 Smart bypass
ECO mode:
The load at output is supplied by the mains via the static bypass.
The mains feeds the rectifiers.
The rectifiers supply the DC voltage and charge the batteries.
In the event of grid failure and/or irregularities in the supply, the UPS s itches to battery mode
ithin 5 ms and supplies load via the UPS modules' inverters.
2
-
7 Bypass Mode: Load supplied via the smart bypass
Online mode (VFI):
The mains feeds the rectifiers.
The rectifiers provide the DC voltage for the inverter and charge the battery.
The inverters supply the load at the output ith the necessary energy
(see Figure 2-3).
In the event of a fault, e.g. overload, short circuits or module malfunctions, the UPS s itches to
bypass mode ithin 5 ms (see Figure 2-7) and supplies the load via the static bypass. Once the
faults have been rectified, online mode is immediately re-engaged.

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 onthe packaging and kept in a dry, ell ventilated room. If the UPS is
not stored in the original packaging, it must be protected from dust and moisture.
3.1 Installation
The UPS must be set up in a clean, dry, dust-free room. The operator must ensure that the room is
adequately ventilated, so that the system is sufficiently cooled and overheating is prevented. Please
observe the set-up diagram in the appendix. If the UPS is supplied ith built-in batteries, the exchange
of air ith the external environment must be in accordance ith EN 62040, appendix N.
3.2 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 follo ing
recommendations are only an indication, as the UPS manufacturer isnot responsible for the electrical
installation.
In all cases, e recommend installing and connecting the input and output in conformity ith local
regulations and standards. In particular, take care to ensure a clockwise rotation phase sequence
during electrical installation. If no error message is generated, the Jovycube ill also operate ith an
anti-clock ise rotating field, and this may result in destruction of the UPS/modules if the manual bypass
is used. In the event that strong electromagnetic fields are emitted, e recommend the use of shielded
cables bet een the UPS and the load.
ATTENTION:
Even hen the mains voltage is s itched off there is a dangerously high battery voltage
inside the device. All installation and connection ork may therefore only be carried out
by a qualified electrician. Before commencing ork, electricians must read this manual
carefully to familiarize themselves ith 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 ith EN 62040!
ATTENTION:
The input line bet een the mains and the UPS unit must be protected against short
circuits!
The use of FI safety s itches before the UPS unit is not recommended.

3.2.1 Fuses and cross sections for cable connections to the UPS
The follo ing table sho s only dimensions (cable current carrying capacity in accordance ith DIN VDE
0298-4) under defined, specified (operating) conditions. Ho ever, because the suitable cable cross-
sections have to be determined for each individual application ith consideration for cable type, routing,
ambient temperature, cable bundling and cable lengths in accordance ith VDE and local regulations,
these values are only applicable under these specific conditions.
The dimensions given belo assume the follo ing conditions:
H07V-K PVC-insulated single-core non-sheathed cable ith a max. operating temperature of
70 °C
Cable routed through electric iring conduit

3.2.2 Connections to the UPS
The UPS should be connected up as sho n in the technical dra ings in the appendix at the end of
this operating manual.
Attention:
The max. Voltage and current of the potential free message contacts is
30VDC/2A.
Notice:
In normal mode, the feed's neutral line is required under all circumstances. If
this cannot be ensured, a transformer forming a neutral point needs to be
connected upstream.
3.2.3 Mounting and connecting the battery
Please refer to the technical dra ings in the appendix of this operating manual for information on
mounting and connecting the battery to the UPS.
Attention:
Unless other ise noted, the battery cables of the battery cabinets or strings must
be connected directly to the UPS.
The reason is the reduced cross section of the cable.
Note:
Observe DIN EN 50272 hen setting up the battery.
