1. General information
To prevent self discharging of the batteries you have to connect the UPS to
The batteries built-in in this system are designed for the necessary bridging time
at nominal load of the UPS. A no-load running operation of the UPS with a long
time in battery operation could led to battery damages. This effect is determined
by the technique of the battery, as the cut-off voltage will not be reached at a
long discharging time.
mains and put it into operation within four weeks after receipt!
Relevant information!
Attention!
Only qualified personal is allowed to open the UPS.
The connection of the UPS has to be done according to VDE considering the local rules.
Don't cover the ventilation slots at backside of the UPS. Keep a distance to the surrounding walls of at least 100
mm.
The UPS is built up according to protection class IP21 and has to be installed in dry and clean rooms with a
surrounding temperature of 20 °C. A lower operation temperature would decrease the autonomy time.
Don't connect devices with connection-cables exceeding the length of 10 meters. This measure serves for the
observance of the EMV-norm.
It's not allowed to carry out structural changes on the UPS. Improper operation causes the extinction of warranty.
To prevent overload or a frequent switch-over to bypass mains caused by non-sinusoidal current peeks
of the connected loads you shouldn't connect laser printer, faxes or similar devices to the UPS.
If it's necessary to connect such devices to the UPS, you have to choose an UPS with a higher nominal
power than the maximum of the current spikes.
The power semiconductors of the UPS could be immediately destroyed by the connection of loads with a

2. Description of the system
This power supply system out of the POWERMASTER M series is an especially build ups for ship use. The
ups is qualified for power supply of important consumers in ship use, such as personal computer, computercontrolled devices and similar units. The output voltage is sinusoidal. In normal operation the connected load is
fed in online operation by the mains through the internal rectifier and inverter. Mains disturbances such as
voltage-variations, distortions, noise etc. are filtered. The internal battery is permanently charged in a careful
way by the charging rectifier in trickle charge mode
3. Description of the functions
Normal operation
In normal operation the battery and the inverter are fed by the rectifier (online-operation).
The conversion of the AC-voltage into DC-voltage and back into AC-voltage ensures a sinusoidal output
voltage with a low distortion. The DC-voltage is also necessary for the battery-charging. The inverter feeds the
connected loads.
Mains failure
In case of mains failure the inverter is fed by the battery.
At the output the output voltage of the inverter is still available.
Inverter failure or overload
In case of inverter failure or overload the load is switched back to the mains.
In case of mains failure the consumers are not supplied in that case any longer.

6. Electrical connection
Only qualified personnel is allowed to work on the UPS-system.
The respective safety regulations have to be considered.
The labeling of the conductors has to be made according DIN40705,2.80 and DINEN60445,09.91!
Ensure a sufficient dimensioning of the protective conductor connection!
During works on the battery dangerous situations may arise caused by the high
dc-voltage and the high short circuit currents. Therefore works on the system
may be carried out only by using suited protective measures, such as insulated
tools, face- and hands protection and so on.
Attention!
Attention!
6.1 Electrical Connection of the UPS-system
At the UPS-system POWERMASTER M 1000 all connections are located on the rear side of the ups and
are fixed.
6.2 Commissioning of the UPS-system
The mains input has to be connected to plug U9:B1 at the rear of the UPS and the load has to be connected
to plug U9:B3.The communication cable has to be connected to plug U9:B2. The ups starts only by
connecting the ups to the mains and switching on the ON button at the front of the ups, for 2 seconds
continuously.
In case of a lightening bar graph at the battery display you have to press down the mains switch ON for 2
seconds.
ONLY FOR 115V – SERIES:
After a short initialization of approx. 5 sec. the following LED's are lightening:
• LINE (input mains)
• BYPASS (direct bypass onto the input mains)
• LOAD (load of the UPS in %)
• BATTERY (battery state in %)
After approx. 5 seconds further on the announcement
• INV (inverter) appears.
The signal BYPASS goes out. The consumer plug backsides the UPS is fed by the inverter now.
For controlling its correct functioning, disconnect the UPS from the mains, but don’t switch it off.
Now the message LINE extinguishes and the messages INV and BACKUP are lightening.
Operating manual POWERMASTER M MIL BAX 3330E page 8
JOVYATLAS UPS-division
The consumer plug is fed by the inverter which is supplied by the battery. As soon as you `ll connect the UPS
to the mains again, the messages LINE and INV will lighten up again and the BACKUP-announcement goes
out.
After controlling the correct operation of all functions the UPS is ready for
servicing the connected consumers!
Now you can connect the consumers which have to be powered onto the consumer plug at the rear of the
UPS. After that switch-on the UPS and wait until the inverter (INV) has switched-on again. After that you
have to switch-on the consumers.
During the connection of devices with fans or transformers, it is possible that the UPS switches over onto
bypass-operation BYPASS because of the high initial currents of the connected loads. That’s a normal
occurrng, the UPS gets back to inverter operation INV after a few seconds.
If you recognize deviations please contact us ( see also page 2).
Attention!
6.3 Shut-down of the UPS-system
To switch – off the UPS, please press the off – button in front of the ups, the ups will be initialized again and
the message 8888 is shown in the display, the load is still supplied by the ups.
To switch-off the complete UPS, please switch off the mains.
For the system POWERMASTER M 1000 you have to switch-off the mains voltage. After that you have to
press down the mains switch of the UPS OFF.

The alarm messages can’t be reset without switching off the UPS-system completely.
- Switch off the complete load at the consumer distribution pole of the UPS.
High relevant devices and so on won’t be supplied further on. If it’s still
necessary to supply them by the UPS, there has to be installed an external
bypass to feed the loads during a failure or servicing of the UPS further on.
Attention
- Switch off the UPS-systems POWERMASTER M 1000 through removing the input mains of the
device. Than you have to press down the push button OFF in front of the display for 2 seconds. After a
delay of 5 seconds the UPS-system will switch-off completely.
- In case of no success please contact our service-department.
8.3 Acoustical alarms (deactivated) and troubleshooting for 115V - Series

Technical deviations are possible
10. Maintenance
In case of longer standstill of the UPS (>= 4 weeks) the battery has to be charged monthly. For this charging
you only have to connect the UPS to the mains for a charging time of at least 8 hours.
However we recommend a charging time for about 24 hours.
The battery in its standard version is maintenance-free. Please note the hints of the battery-manufacturer in
case of using a special battery.
The ventilation slot at the backside of the UPS has to be clean, without any dust or something soiling to
prevent a reduced air-exchange. Please observe the necessary distance to surrounding walls of at least 100
mm.
Half a year you have to check up the perfect function of the UPS. Therefore you have to disconnect the UPS
from the mains with connected load / consumers.
We recommend the use of a remote control system in case of UPS systems which can’t be controlled directly.
