IV. PARALLEL OPERATION

4.

1 Introduction

Two (or more) identical DS300-110 series UPSs can be interconnected for parallel operation.
The main purposes for parallel use of DS300-110 series UPSs are:

      -Redundancy for Increased Reliability
      -Power Increase

     Although recent UPS designs are perfect and have high MTBF figures, a second (or more) UPS can be
used  in  parallel  with  the  first  one,  for  supplying  the  critical  load  in  case  of  any  possible  failure  of  the  first
UPS. In such an application the faulty UPS is isolated automatically from the parallel system and the other
UPS (or UPSs) continues to supply the critical load. Use of Redundant UPSs in parallel, therefore, provides
increased reliability for the critical load connected to the parallel system output.

     If  power  demand  increases  in  a  certain  UPS  application  exceeding  the  power  rating  of  an  already
installed stand-alone UPS, a second (or more) UPS of the same model and power rating can be added in
parallel to the existing UPS to increase the output power capacity.

      Schematic diagram of parallel connection of two DS300-110  series UPS units is shown in Figure 4.1
