UPS-1000-B1
Revision 1 8
B Introduction and description
Read carefully before initial operation !
This manual shall help the user to get familiar with the product and its components and features. It shall
provide information as accurately and completely as possible.
The manual as well as all documents has to be read and followed strictly before installation. Otherwise in
certain situations warranty and guarantee can be cancelled partly or completely. Any liability on the part of
Bicker Elektronik is excluded for possible existing errors as well as non-compliance with the instructions for
use and installation.
B1 Description of the product and its functions
The UPS-1000-B1 is a uninterruptible Power Supply (UPS) with Line Interactive Design. In contrast to a con-
ventional off-line UPS, it has a sine voltage output. The UPS can be operated with a BP-2480 battery pack up
to +60 °C operating temperature.
The primary use of the UPS is to supply the connected application during power failures and /or voltage fluc-
tuations. The application which should be protected is connected to the output of the UPS.
In the event of a voltage drop or a voltage fluctuation of the input voltage (below undervoltage limit), the UPS
is switched to battery mode (also backup mode). In this state, the application at the UPS output is supplied via
the inside energy storage device. The backup time (also buffer time) depends on the available energy of the
installed battery pack, the level of the connected load current and the software settings of the UPS.
In the event of a power failure and the set backup time in UPSilon2000 has expired, the operating system of
the PC is shut down and the UPS is switched off.
In the event of a power failure and the return of the input voltage during the shutdown of the operating
system, the operating system is shut down by the UPS management software UPSilon2000. The UPS then
switches off the output for a short time. After a few seconds, this reboot function automatically switches back
to mains operation. The downstream PC can then automatically start here (BIOS setting PC). In addition, the
energy storages are recharged.

F General Data
F1 Assembly and installation advice
Installation and operation of this device is only allowed to be executed by a qualified
electrician! The application has to be separated from any power during the mounting process.
Wires have to be connected safely and must not have contact with sharp edges. Before com-
missioning, check all the connections for correctness!
Please check the shipping box for any transport damage immediately upon receipt. If you have any problems,
please contact your forwarding agent or parcel service. Please always send the UPS in the original box .
Plug the enclosed power cord into the UPS (2) and into a 3-pin
socket (with PE). Connect the load (e.g. PC) to the mains output of
the UPS (3). Plug the enclosed USB or green RS232 cable to USB and
PC and install UPSilon2000 on the PC.
The 3-pole mains connection of the UPS-1000-B1 has to be con-
nected to a 3-pole circuit (with PE / earth) protected with 16 A. The
sum of the leakage currents (UPS and connected devices) must not
exceed 3.5 mA. The UPS-1000-B1 can be live even in the event of
a power failure!
F2 Convection and installation position
• The UPS-1000-B1 may only be installed in an upright position.
• It must be ensured that the UPS-1000-B1 may bot be loaded beyond maximum load.

Revision 1 19
G14 Load sensor / Green Mode
Scenario: The PC is shut down manually using the mouse (with , on / off, shutdown), followed by
a „power failure“ by e.g. the EVU. A standard UPS without a load sensor would switch to battery operation and
buffer the standby mode of the switched-off PC until the battery is discharged. By switching on and adjusting
the load sensor / green mode on the UPSI-1000-B1, the connected load can be thrown off if it falls below the
limit.
When Gn.x (x: number) flashes, press any selection button or for 1 second to change the load sensor! The
settings keep changing every 2 seconds, if you press the button.
Gn.0: Load sensor is deactivated.
Gn.1…9: Load sensor / green mode is deactivated and can 1…9 % of the nominal load of the UPS (600 W).
To get to the next menue item, press both selection buttons and . If you do not press it again, the LCD
display will stop flashing after 30 seconds and the setting will be completed.
12
4.11.5 Lastsensor/Green Modus
Szenario:
Ein PC wird manuell per Maus (Windows: Start/Beenden/Herunterfahren) heruntergefahren. Dann
gäbe es einen Stromausfall durch das EVU oder es könnte auch ein vorgeschalteter Netzschalter
einer Maschine ab geschalten werden! In diesem Fall würde die USV in den Batteriebetrieb
schalten und die Stand By Schaltung des PC’s oder das angeschlossene Netzteils puffern bis die
Batterie entladen ist. Durch Einschalten und Justierung des Lastsensors/Green Modus kann die
angeschlossene Last bei Unterschreiten abgeworfen werden.
Wenn Gn.x (x Zahl) blinkt, drücken Sie eine beliebige Auswahltaste △bzw. ▽für 1 Sekunde,
um den Lastsensor zu ändern! Die Einstellung wird sich alle 2 Sekunden ändern, wenn man die
Taste betätigt.
Gn.0 Der Lastsensor ist deaktiviert.
Gn.1….9 Der Lastsensor/Green Modus ist deaktiviert und kann von 1…9% der nominalen
Leistung der USV (600W).
Zum nächsten Menupunkt gelangen Sie durch gleichzeitiges Drücken der beiden Auswahltasten
