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 not have an output transformer and
is therefore not galvanically isolated from the mains!!
P L E A S E N O T E!
The batteries used are just designed for the required backup time to supply
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.
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 21 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.
2. Description of the System
Power supply devices of the model range WÄRTSILÄ JOVYTEC PMS are particularly suited for supplying
critical loads 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.

Wärtsilä JOVYTEC PMS 2002K / 3002K BAX 4837E - 7 -
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.

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. At the output the
voltage from 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 chapter “UPS internal manual bypass”.
Other procedures could lead to destruction of the UPS unit or crashing of the power consumer loads.

6. Electrical connection
The UPS unit in the series POWERMASTER is simply connected by means of the supplied input cable and
the input socket.
One proceeds as follows:
1. Plug the mains input cable provided into the suitable power socket.
2. Attach the critical loads by means of the output sockets.
3. Connect up the battery pack supplied by means of the the battery connection.
4. All connecting up work is now complete.
P L E A S E N O T E!
Only trained personnel are allowed to work on the UPS unit.
Observe all corresponding 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.

6.2 Commissioning the UPS unit
Take note: The unit fans run as soon as the input voltage is applied!!
The UPS unit can now be started by pressing the ON/OFF button in the front panel for 3 seconds; a
message appears in the display: Switching on procedure. The UPS unit now starts a self-test routine
during which its internal functions are tested and the mains synchronisation and the inverter are started. The
message “Battery mode“ is shown in the display during the self-test and the LED´s ON for UPS ON and
ON-LINE output voltage light up. The message “Operation“ appears in the display. The loads to be
supplied can now be switched on.
Please contact us if anything different happens.
6.3 Shutting-down the UPS unit
When shutting down the unit please proceed as follows:
- Switch off all consumers
- Press the ON/OFF button in the front panel for 3 seconds. An acoustic sound (bleep) is emitted while
pressing the ON/OFF button and the message: Switching off soon appears in the display, and then
the message “UPS OFF“. The UPS unit is now shut-down. Please note: The internal fans of the UPS
will continue to run as long as the input voltage is applied.
P L E A S E N OT E!
The unit should be started over the input mains. If the input mains is not available for a short
time then it is also possible to start the unit over the external battery. It is a basic prerequisite for
this operating mode that the UPS unit was one time operated over the energy supplier’s mains
network. Please note that when starting over the external battery, the maximum time the output
voltage is available to you is the autonomy time. The UPS unit will also start with the previously
stored parameters, i. e. if the mains previously had 50 Hz then the UPS will also generate 50 Hz
on the output side.
P L E A S E N OT E!
The DC-voltage specification on the UPS must match to the voltage specification on the battery
cabinet (DIRECT CURRENT LINK VOLTAGE) otherwise there is danger of destroying internal
components of the UPS or destruction of the battery.

The ENTER key can be used to query the parameters which have been set for the UPS unit. Pressing the
ENTER key for 2 seconds on a running UPS unit will automatically cause the first parameter to be displayed for
10 seconds. Pressing the ENTER button again allows one to manoeuvre through the parameters. If the next
parameter is not selected within 10 seconds then the UPS unit indicates its condition again.
4. FUNC key
The FUNC key can be used to set a parameter such as the output voltage etc.
The formalism is as follows:
Press the FUNC key on a running UPS unit for 2 seconds to start the menu for the UPS unit parameters.
Pressing of the ENTER button selects the parameter to be altered. Once the parameter to be altered is reached
then the desired value can be selected by pressing the FUNC button. Pressing the ENTER button a second
time accepts the desired parameter and stores it.

function panel.
The conditions are as follows:
5. ON Operation : This LED lights green in case the UPS is switched on
6. ON-LINE Operation : This LED lights green both in UPS mode and in
bypass mode, signalling output voltage available.
7. ON-BAT Battery operation : This LED lights yellow for battery operation
( Input power failure)
8. BYPASS BYPASS : This LED lights yellow indicating UPS-bypass mode
9. FAULT FAULT : This LED lights red in case of an internal error of the UPS,
and an accoustic signal is emitted. Press any key in the
function panel and the alarm will be switched off. The cause
of the alarm is shown in the display.
