  • Page 42: Parallel Operation

    V. PARALLEL OPERATION 1 Introduction Two (or more) identical DS300 series UPSs can be interconnected for parallel operation. The main purposes for parallel use of DS300 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.

  • Page 43: Parallel Operation Mode Settings

    The AC inputs of all UPSs in the parallel system are connected to the same mains, and all the AC outputs are connected to each other. Each UPS has its own battery group. The critical load is connected to the common output of the parallel system. There are also some signal cable connections between the UPS units necessary for parallel operation, and will be described later.
