  • Page 11: Introduction

    INTRODUCTION GENERAL DESCRIPTION The LP 33 Series Uninterruptible Power Supply (UPS) provides the energy supply for critical loads which need a reliable, continuous free from voltage disturbances and frequency fluctuations supply. In case the mains fails, or it exceeds the permitted tolerances, the energy to supply the load is furnished by the battery with a backup time dependent on its capacity, until the mains recovers.

  • Page 12: Description

    If chosen the ECO Mode, the SSM transfer the load from mains to inverter in case the utility fails. Back-Feed Protection All LP 33 Series UPS’s are equipped with an automatic system for the protection against voltage back feeding towards Utility, through the Bypass (Applied Standard IEC 62040-1).

  • Page 13: Operation Modes

    ECO Mode cannot be enabled for RPA Parallel System. Attention: A single unit equipped with a RPA - Parallel board, must be considered as parallel, thus disabling ECO Mode. Modifications reserved Page 13/85 OPM_LPS_33E_10K_30K_4GB_V030.doc Operating Manual LP 33 Series / 10-20-30 kVA...
