N O T E!
The UPS should be attached to the mains supply and switched on at the latest 4
weeks after receipt in order to prevent the battery discharging itself.
P L E A S E N O T E!
In order to exclude the possibility of overloading or constant switching over to bypass
due to consumer generated non-sinusoidal current peaks, no devices such as laser
printers, fax machines as well as devices operating with a similar technology should be
connected to the UPS. In cases where it is essential that such devices be operated then
a UPS must be selected whose capacity can match the maximum possible current
peaks. Devices with power reduction due to half wave power consumption, (e.g. coffee
machines, hair dryers) can lead to immediate destruction of the power-output stage. The
battery is not galvanically isolated from the mains so occurrence of a mains voltage at
the battery terminals is possible! The UPS unit does have an output transformer and is
therefore galvanically isolated from the mains!!
P L E A S E N O T E!
The batteries used are just designed for the required bridging time to meet the
nominal load of the UPS. Operation of the UPS unit in free running mode for a
longer period of time on battery can damage the batteries. This effect is due to
the nature of the battery since for a longer discharge period the final
discharging voltage is not reached.
P L E A S E N O T E!
These ups –systems are equipped with an galvanically isolated output transformer.
The secondary winding of the output transformer has two seperate windings with each
115V. These windings are connected in series to 230V. If an earthed output is needed, so
the input neutral and the output neutral have to be connected!!
1. General notes
The device may only be opened by trained specialists.
The system is to be connected up and earthed according to VDE regulations. Provisions of the local energy
–supply company must be observed.
The ventilation slits on the front and rear sides must not be covered and a distance from the wall of at least
100 mm is essential.
The UPS unit is built according to Protection Class IP 20 and is designed for installation in heated internal
spaces (at 20°C). A lower operating temperature lowers the bridging time.
No devices with a connecting cable in excess of 10 metres in length should be connected to the UPS. This
measure serves to ensure observance of the EMC standard.
No alterations should be made to the UPS unit. The warranty will expire in cases of inappropriate physical
interventions.

P L E A S E N O T E !
The output of the UPS unit also carries a voltage in the case of a power failure!
This is why the installation engineer must mark the outputs and power
sockets on the UPS unit clearly according to EN 62040.

2. Description of the System
Power supply devices of this model are particularly suited for supplying important power consumers in
industry and the office such as personal computer, computer-controlled devices, PLCs and similar
equipment. The output voltage is sinusoidal. In normal cases the attached consumers are supplied with
power from the installed rectifier and installed inverter from the mains power supply network (online
operation). Any disturbances in the mains such as voltage peaks, voltage drops, harmonic distortions or
noises etc. are filtered out. The installed battery is constantly being charged up by means of a charging
rectifier with a charge preservation charging stage which is gentle on the batteries.
3. General description of the function
Normal operation
During normal operation the battery and the inverter are supplied with power via a rectifier (online operation).
The change-over from alternating voltage to direct voltage and back to alternating voltage again is achieved
by a sinusoid output voltage with a low distortion factor. The direct voltage is also needed for charging the
battery. The inverter supplies the attached consumers.
Figure 1: Block diagram “Normal operation“
Power failure
In the case of a power failure, the energy needed by the inverter is taken from the battery. The output voltage of
the inverter is still available.

P L E A S E N O T E!
An operating fault can lead to total loss of power supply to the attached power
consumer loads! A power failure for a switched in manual bypass will lead to
crashing of the power consumer loads!
Fault in the inverter or an overload (bypass operation)
In the case of a fault occurring in the inverter or an overload, a switch-over device switches the load back to
the mains. This means that, in the case of a power failure, the connected consumers will no longer be
supplied with power.
Figure 3: Block diagram “Fault in the inverter“
Manual bypass (service bypass)
If there is a fault in the UPS unit and service work must be undertaken, the UPS unit is fitted with an internal
bypass for that purpose. When actuating the manual bypass, the load is directly supplied from the mains.
This means that, in the case of a power failure, the connected consumers will no longer be supplied with
power. When using the manual bypass it is essential to observe the formalism described in Chapter “internal
Manual Bypass”. Other procedures could lead to destruction of the UPS unit or crashing of the power
consumer loads.

The voltage L1´and L2´can be connected in series with the voltage L3´and L4´.
(Connection between L2´and L3´is standard delivery status). Both potentials can
also be connected in parallel (Customer whish). If there is no interconnection
between terminal 10 and terminal 17, than the output voltage is galvanically
isolated from mains and you will build an earthed isolated mains at the output of
the ups. This makes it necessary to use an isolation monitoring unit at the output
of the ups. At the standard delivery the connection for earthed output has
been made on manufacturer side!!
6. Electrical connection
6.1 Electrical connection WÄRTSILÄ JOVYTEC L 6000
The UPS unit is simply connected via terminals at the rear side of the ups. Before connecting the UPS, the
cover plate has to be removed. To insert the cables there are three cable inlets inside the cover plate. The
connection for the terminals is as follows:
1 = Battery +
2 = Battery –
3 = PE
4 = Feeding L1 from bypass (connection between terminal 4 and 5 is possible or separate feeding.
5 = Potential L1 internal from terminal 8
6 = Neutral for bypass (internal connection to terminal 9)
7 = PE for bypass
8 = Feeding L1 for mains input
9 = Neutral for mains input
10 = Neutral for connection to neutral output (earthed)
11 = PE for mains input
12 = Potential L1´(L1´= L1)
13 = Potential L2´ (The voltage between terminal L1´and L2´is 115V)
14 = Potential L3´

16 = Neutral N (The voltage between terminal L1`(terminal 12) and N (terminal 16) is 230V)
17 = Neutral N (for connection with input neutral for earthed output voltage)
18 = PE Output
P L E A S E N O T E!
Only trained personnel are allowed to work on the UPS unit.
Observe all correponding safety regulations.
Marking of cables is to be according to DIN EN 60445!
When connecting to the UPS unit, ensure use of an adequately sized protective-
conductor connection!
P L E A S E N O T E!
When working on the batteries it is possible for dangerous situations to arise
due to a high DC voltage and high short-circuit currents.
This work on the device must only be conducted when accompanied by use of
suitable protective measures such as insulated tools, eye and hand protection
etc.

9. With this variance of connection a galvanically isolated output is set up. This requires an
additional isolation monitoring unit.
10. If an addditional battery cabinet is in use. Please connect the battery cable to the terminal at the
terminals 1 (B+), 2 (B-), 3 (PE). Attention: Please take care of the polarity!!
11. Fix the cover plate with a Phillips Screw Driver
12. Switch on the input switch
13. Connect the battery pack to the battery jack on rear side of the UPS
14. Switch on the output switch
15. The electrical connection is herewith already done
P L E A S E N O T E!
Both mains feeding must have the same connection.
Don´t exchange L1, N , PE, this will cause a short circuit which will destroy the UPS!!
