  • Page 47: Parallel Operation

    V. PARALLEL OPERATION 1 Introduction Two (or more) identical DS300T series UPSs can be interconnected for parallel operation. The main purposes for parallel use of DS300T 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 48: Parallel Operation Mode Settings Of Ds300 Series Upss

    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.

    VII. MAINTENANCE ATTENTION !!! There are no parts inside the UPS or battery group that needs service or maintenance work that should be done by user. Therefore DO NOT OPEN THE COVER OF UPS. Never touch on any terminal of battery group. There is risk of electric shock inside the UPS even when it is completely turned off (because of energy storage components).

  • Page 60: Annual Maintenance

    Take notes if possible when you are examining the UPS. Compare the notes with previous ones and try to determine if there is a change or not. If there is a difference between the previous notes and the new ones, search for and record any new load added to UPS output between two records and the magnitude, place and type of the new load, if possible.
