13.1
Extended backup times
The UPS unit needs two or more battery racks to achieve longer backup times.
The WÄRTSILÄ JOVYTEC PMS 2002k / S 3002k allows one to connect up to two or three battery packs in
parallel.
13.2
Battery operation
In the case of a network failure the consumers are supplied without interruption from the battery.
In battery operation the LED
ON-BAT
(Battery operation)
lights up and an acoustic warning tone sounds
every 5 seconds. The acoustic warning tone changes towards the end of the backup time, i.e. the battery is
virtually discharged, to two bleeps sounding every 5 seconds. The backup time generally allows intended
shutdown of computers or initiate data storage/back-up, without losing data or having running processes
interrupted in an uncontrolled manner. The backup time can be extended significantly by switching off
individual, less important consumers.
Restoration of mains power before total discharge of the battery:
In the case of restoration of the mains power before the end of the backup time, the inverter continues to run
automatically until the battery is charged up.
Restoration of mains power after total discharge of the battery:
At the end of the backup time the inverter switches off automatically and the consumers are
no
longer
supplied with power.
When the mains power is restored, the consumers begin again to be supplied with power via the inverter.
The inverter is switched on again automatically. The battery is charged up again automatically after
restoration of the mains power.

!
Before plugging in the battery plug, the voltage at the battery jack on the UPS unit and the
battery used must be checked to ensure that they both have the same voltage and polarity. The
attached markings (DIRECT CURRENT LINK VOLTAGE) and a control measurement using a
suitable measuring device serve to achieve this.
The battery is not galvanically isolated from the mains so occurrence of a mains voltage at the
battery terminals is possible. The UPS unit should be disconnected from the mains before
working on the battery.
Do not cover the ventilation slots or the battery slots in order to avoid any excessive increase in
the battery temperature.
The battery rack should be connected to the mains and switched on at the latest 4 weeks after
receipt in order to prevent battery self-discharging.
