GREEN POINT The parallel system modification does not require the UPS to be manually calibrated in any way, the calibration of the systems is handled automatically by the microprocessor digital control system, this controls the exchange of information and ensures that the load distribution between the various UPS systems is equal.
GREEN POINT (on-line). When the mains supply returns to within the acceptable limits, the system will first ensure that the supply remains stable, before switching the load back onto the mains supply. During both of these operating modes, the load is powered directly from the mains supply via the bypass. However, due to the EMI filters in both the input and output, the mains supply is filtered and therefore free of any electrical disturbances.
GREEN POINT The UPS can be configured to automatically restart after a mains supply failure or after the batteries have become fully discharged. The Auto-Restart function may be delayed using the built-in software. Cold Start (no battery): Enables the UPS to be switched on during the absence of the mains supply (optional).
GREEN POINT Easy to install and maintain Simplified installation: The UPS can be connected to either a single-phase or three-phase power supply without any internal modifications necessary. Castors to ease installation, movement and maintenance of the system . Adjustable output voltage via the control panel. This enables the output voltage from the system to be increased to compensate for the drop of voltage through the cables to the load, guaranteeing the rated voltage to all users.
GREEN POINT The software enables the user to programme the automatic start-up and shutdown of the system on a weekly basis. The UPS also contains the following hardware interfaces: - double RS232 serial port voltfree contacts interface slot for the installation of a network adaptor EPO (Emergency Power Off) contact for UPS emergency power off using a remote emergency button.

GREEN POINT 5.2 Standards relating to systems and installation The above product regulations refer specifically to uninterruptible power supply systems. It is these regulations that manufacturers of uninterruptible power supply systems are obliged to adhere to. However, with regard to the electrical system, the installer must refer to other standards.
GREEN POINT 6 - INSTALLATION INSTRUCTIONS 6.1 Electrical system requirements 6.1.1 Protections UPS INTERNAL PROTECTION The size of the circuit breakers and fuses positioned in the UPS input/output lines are shown in the table below (refer to the block diagram section for an explanation of the abbreviations). Any fuse that requires replacement must only be replaced with a fuse of the same type and rating, as indicated in the table below.
GREEN POINT Differential (Residual Current Device (RCD)) In the standard version, where no input isolation transformer exists, the mains supply input neutral is connected to the UPS output neutral. The UPS does alter the arrangement of the neutral regime within the system, as a result, the electrical systems both up stream and down stream are identical. Additional differential (RCD) devices may be installed on the output of the UPS, corresponding to those installed on the input.
GREEN POINT CONNECTING THE SUPPLY AND LOAD UPS with single-phase output (three-phase + neutral input) PE L1 L2 L3 N L N PE Refer to the table below for the recommended cross sectional area of the input and output cables.

The load is constantly supplied by the inverter with a stabilised and regulated voltage and frequency.
GREEN POINT STAND-BY FUNCTION: The UPS can be programmed to operate in stand-by mode. During this mode, the UPS output remains off whilst the mains supply is present and activates only when the mains supply fails. The inverter start up is progressive (320 msec), to prevent current surges occurring due to loads such as lights etc. SP121E Rev. 000 Siel S.p.A. Issued date: 2005-05-06 Pag.

GREEN POINT LEDs The LEDs can be either lit, flashing or off, thus providing immediate information on the UPS status. IN LED (green): input supply. Lit: The input supply is within a preset range (voltage or Frequency); Flashing: The input supply is not within a preset range (voltage or Frequency); Off: No input supply present. OUT LED (green): inverter output line. Lit: The UPS output is supplied by the inverter, if the BY (yellow) is also lit, the UPS is in Stand by mode.
GREEN POINT 10.2 Liquid Crystal Display ( LCD ) LCD display: status messages During Normal Operation mode, where no specific information has been requested and/or no particular command has been made using either the buttons on the control panel or via the RS232 remote line, the LCD will display a number of basic messages.
GREEN POINT 10.4 Alarm messages The alarm messages that appear on the first line of the display panel are listed below. The alarm number in brackets indicates the level of priority. [1] DISTURBANCES ON THE BY-PASS LINE This alarm is present whenever there is a disturbance on the by-pass line (such as a voltage peak or harmonic distortion, whilst the voltage and frequency are correct).
GREEN POINT This alarm is present if one of the following conditions occurs: − − the incoming mains supply voltage is insufficient. the output load, measured in active power [W], exceeds the rated value. [8] OUTPUT OVERLOAD Indicates that the power drawn by the load and provided by the inverter exceeds the permitted value. The value indicated, expressed in %VA, exceeds 100%. This alarm is activated whenever the peak current absorbed by the load exceeds the maximum value permitted.
GREEN POINT This transitory phase occurs, for example, when the machine has just been switched on, or when it is waiting to return to inverter mode after having been switched to by-pass mode due to an overload. [12] BY-PASS FOR OUTPUT OVERLOAD (fixed or flashing message) If the message is flashing then the alarm has been memorised. Indicates that the by-pass line overload has been memorised. The overload must persist for a certain amount of time in order for it to be memorised.
GREEN POINT This alarm is present when the total shutdown command has been activated using either the control panel or the RS232 connection. The system carries out the command after a delay of several seconds, giving the user time to cancel the command, if required. The command is memorised even when the system is shutdown due to insufficient power supply. [20] REMOTE SYSTEM OFF COMMAND: ACTIVE As per the alarm above, but with the command activated via the "REMOTE" connector.
