    ULTIPLE XPANSIONS Several Battery Boxes can be connected in a cascade to ensure prolonged autonomy. The connections should be made as shown here below: WARNING (only for single UPS): No more than one UPS may be connected to each Battery Box or to more than one Battery Box connected in a cascade.

  • Page 28: Use

    ESCRIPTION The purpose of a UPS is to ensure a perfect power supply voltage for the devices connected to it irrespective of whether mains power is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a stable amplitude and frequency, irrespective of the changes and/or variations occurring on the electricity network.

  • Page 29: Preliminary Operations

    RELIMINARY PERATIONS Visual check of the connection Check that all the connections have been made strictly following the indications given in the "Connections" paragraph. Check that the "1/0" button is in its "0" position (see "Front Views of the UPS" point 5). Check that all the isolators are open.

  • Page 30: Powering On For The First Time

    OWERING ON FOR THE IRST Set the "1/0" button to "1" and wait for a few seconds. Check that the display is turned on and the UPS enters "STAND-BY" mode. Check that no error messages appear indicating that the input cables do not respect the correct cyclic phase sense (for three-phase input only).

  • Page 31: Powering On From The Mains

    OWERING ON FROM THE AINS Set the “1/0” switch behind the door of the UPS in its “1” position. After a few moments, the UPS is turned on, the capacitors are precharged and the "Lock / stand-by" LED blinks: The UPS is in stand-by mode.

  • Page 32: Graphic Display

    RAPHIC ISPLAY At the centre of the control panel there is a large graphic display, which provides, in the foreground and in real time, a detailed overview of the current status of the UPS. Directly from the control panel you can turn the UPS on/off, view the electrical values of the mains, output, battery, etc., and make the main machine settings.

  • Page 34: Operating Modes

    PERATING ODES The mode that guarantees maximum protection for the load is ON LINE mode, in which the energy for the load is converted twice and is generated perfectly sinusoidal at the output with the frequency and voltage set by the fine digital control of the DSP irrespective of the input (V.F.I.).

  • Page 35: Programmable

    EDUNDANT UXILIARY OWER UPPLY FOR UTOMATIC YPASS The UPS is equipped with a redundant auxiliary power supply that enables the UPS to run on an automatic bypass even when a failure occurs in the main auxiliary power supply. If a fault occurs in the UPS shutting off the main auxiliary power supply, the load is powered by the automatic bypass.
