High level of reliability - Voltage filtered, stable and reliable (On Line double conversion technology in accordance withstandard EN50091-3) with filters for suppressing atmospheric disturbances:the on line technology provides the maximum protection for the loads.The double conversion stage filters and stabilises the input voltage, and reproduces it free of anymains disturbance (overvoltages, variations in frequency and voltage, etc.).The standard (EN50091-3) defines this technology as VFI (Voltage and Frequency Independent)because the output voltage and frequency are completely...

GREEN POINT Absolute protection -The Ups is equipped with contactors to prevent any return of energy which would put maintenanceworkers at risk, should a fault on the by-pass line or to the rectifier circuit occur. In addition, shouldthere be a leakage current on the by-pass when the unit is operating in inverter mode, the UPSautomatically switches to the by-pass. Input relays both for the single-phase input and for the three-phase input are available. These relays open and isolate the Ups from the mains power supply.The combination of these two protections allow technical staff to carry...

GREEN POINT After the battery has intervened, the power supply to the load is disconnected after a certain delay(3 sec. to verify that the mains has effectively entered into acceptable tolerance limits) when the mains power supply returns. This delay may be programmed using software, from 3 secs to anumber of hours, to provide a delayed and programmed start-up of the users connected to the UPS(e.g. main lights). Flexibility of use -Autorestart Autorestart ( programmable automatic restart when the mains power supply returns ): The system will automatically restart after it has shutdown after...

GREEN POINT - Ease of maintenance thanks to the manual by-pass provided This function is available for the entire range and allows you to carry out maintenance work on site.This function deactivates the system without disconnecting the power supply to the loads. Themanual by-pass transfers the load from the inverter to mains and vice versa, without interruptingthe output power supply. - Reduced dimensions: due to the following characteristics:. microprocessor control. IGBT technology. internal batteries. ventilation (frontal input, rear output: this eliminates the need to keep a lateral...

The company quality system has been certified as conforming to ISO 9001 (Certificate No ITALCERT-005/95). This covers all of the procedures, operating methods, and controls from the designstage right up to the production and sale of the unit. > EN50091-1: Uninterruptible power supply systems (UPS): general provisions and safety provisions ratified 9/12/92, with application obligatory from 15/3/94. EN50091-1-1: Uninterruptible power supply systems (UPS): general provisions and safety provisions used in areas accessible to the operator EN60950 (CEI74-2): ITE (Information Technology Equipment)...

GREEN POINT 89/336 electromagnetic compatibility directive enforcing the obligatory CE marking from 1/1/96.This directive concerns all issues of immunity and emissions relating to the UPS at its placeof installation. > These standards are: - standard CEI 64-8 (HD384/IEC6036) for electrical systems in general - standard CEI 64-8 variant 2: for installation in hospital environments - standard CEI 11-20: for systems with UPS machines connected to category I or II networks - standard CEI 17-13 (EN60439-1) concerning control equipment - standard CEI 21-6/3: for battery installation (shortly to...

GREEN POINT Single-phase mains and single-phase load connection: Short circuit the input terminals using the jumper provided in the accessory box.Connect the input and output cables to the terminal board as indicated in figure 2. Fig.6 Fig. 2 Input/output terminal board Fig. 3 Input/output terminal board Three-phase mains and three-phase load connection Connect the input and output cables to the terminal board as indicated in figure 3. When operating in by-pass mode (automatic or manual), the load is powered directly from the mainsvia the L1 line. Therefore the line must be sized...

1) Input protection (fuse).2) EMI input filter + back-feed protection: Input and output filters for electromagnetic disturbances.Back-feed protection: intervenes if the mains power supply fails, isolating the UPS from the inputsocket to prevent the mains power supply from returning. This protection is required to preventvoltage from returning to the line, which may put the operator at risk when carrying outmaintenance work. This fuse is selective in relation to the input fuse (1): a fault occurring to the rectifier/booster willopen this protection before the input fuse intervenes, thus...

GREEN POINT 11) Battery charger: This is a DC-DC converter that converts the rectifier/booster output voltage to the level required torecharge the batteries. It is deactivated when the mains power supply fails 12) Battery protection: Fuse. 13) Manual by-pass By closing the maintenance by-pass (SWMB) switch and then opening the SWIN and SWOUT,switches, it is possible to carry out maintenance work on the UPS, in total safety, withoutinterrupting the power supply to the load. The auxiliary contact used to communicate the closure of this switch to the microprocessor can be found on the input...
