Page 10: Battery Box ( Optional )
ATTERY OPTIONAL THE BATTERY BOX IS AN OPTIONAL ACCESSORY. The Battery Box contains batteries that increase the operating time of the UPS during prolonged black-outs. The number of batteries contained in it will vary according to the type of UPS to which the Battery Box is to be installed. The utmost attention must be paid to ensure that the battery voltage of the Battery Box corresponds to that supported by the UPS. -
Page 11: Separate Bypass Input ( Optional )
EPARATE YPASS NPUT OPTIONAL (OPTIONAL) VERSION OF THE UPS SERIES HAS SEPARATE BYPASS AND INPUT LINES. The UPS series with separate Bypass ensures a separate connection between the input and bypass lines. The UPS output is synchronised with the bypass line so as to safeguard against incorrect voltage changeovers in the alternate phases, in the event of automatic bypass or closing of the maintenance switch (SWMB). -

LECTRICAL ONNECTIONS WARNING: a 4-wire three-phase distribution system is required. The UPS must be connected to a power supply line made up of 3 phases + neutral + PE (protective earth) of TT, TN or IT type. Therefore, the phase rotation must be respected. Optional TRANSFORMER BOXES to convert the distribution systems from 3 wires to 4 wires are available. - Page 18 UPS without any variation in neutral condition and with separate bypass input UPS with galvanic isolation and with separate bypass input UPS with galvanic isolation at output and separate bypass input...
- Page 19 Separate bypass: if the separate bypass option is present, protective devices must be present on both the main power supply line and the bypass line. Note: the neutral of the input line and that of the bypass are commoned inside the equipment, so they must refer to the same potential.

Page 29: 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 30: 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. -

Check that no error messages appear indicating that the input cables do not respect the correct phase direction. In this case, the following operations should be performed: Switch off the UPS by moving the “I/0”... -
Page 32: Powering On From The Mains
OWERING ON FROM THE AINS Power the UPS by closing the SWIN input switch and leaving the SWMB maintenance switch open; if present, set the “1/0” switch to “1”. 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 35: 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 36: Redundant Auxiliary Power Supply For Automatic Bypass
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. -

Page 47: Status / Alarm Codes
TATUS ALARM ODES Using a sophisticated self-diagnostic system, the UPS can check and indicate on the display panel its status and any errors and/or faults that have occurred during its operation. When a problem arises, the UPS signals the event by showing the code and corresponding type of alarm on the display. - Page 48 Anomaly: “minor” problems that do not bring the UPS to a halt but affect its performance or inhibit the use of some of its functions. CODE DESCRIPTION Inverter Desynchronized External synchronism failed Overvoltage on input line of Phase1 Overvoltage on input line of Phase2 Overvoltage on input line of Phase3 Undervoltage on input line of Phase1 Undervoltage on input line of Phase2...
- Page 49 Fault: more critical problems than “Anomalies” in that, if they persist, they may bring the UPS to a halt. CODE DESCRIPTION Internal communication error Incorrect input phase direction. Input fuse of Phase1 broken or input relay blocked (will not close) Input fuse of Phase 2 broken or input relay blocked (will not close) Input fuse of Phase3 broken or input relay blocked (will not close) Input relay of Phase1 blocked (always closed)
- Page 50 Lock: indicate a breakdown of the UPS or one of its parts. Locks are normally preceded by an alarm signal. In the event of a fault and resultant breakdown of the inverter, the inverter will be switched off and the load will be powered by the bypass line (this procedure is excluded for breakdowns caused by high and persistent overloads and by short circuits).
