Page 8: Presentation
PRESENTATION USS3T – USS3M 10/15/20 USS3T – USS3M UPS Systems are intended to ensure a perfect supply voltage for the equipment connected to it, both with and without a power supply network. Once connected and powered, the system generates an alternating sinusoidal voltage, with stable amplitude and frequency, regardless of surges and/or variations affecting the electrical supply. -
Page 9: Description
ESCRIPTION The purpose of a UPS is to provide a perfect power supply voltage for the devices connected to it, irrespective of whether the mains power supply is present or not. Once connected and powered, the UPS generates a sinusoidal alternating voltage with a stable amplitude and frequency, regardless of any changes and/or variations occurring on the electricity network. -

Page 14: Ups Operation
UPS OPERATION PERATING MODES The UPS can be configured for different operating modes. The following operating modes as listed below may be selected. ON LINE MODE When in ON LINE mode, the system operates in ON LINE double conversion. This mode provides maximum protection for the load. During operation the energy coming from the electrical supply network (AC), is converted into a clean and stable output. -
Page 15: Battery Working
ATTERY WORKING When the UPS is supplying the output with the batteries present, if the mains supply network falls outside the pre-set tolerances, for example in case of a blackout, voltage or frequency disturbance, the system automatically switches to BATTERY OPERATING STATUS and draws power from the batteries to support the load. -

Page 58: Locks
OCKS Locks 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). - Page 59 TROUBLESHOOTING GUIDE Irregular operation of the UPS is very often not an indication of a fault but is simply caused by simple problems or distractions. We therefore recommend you consult the table here below, which provides some information that will help you to solve the most common problems.
