    In this case, please contact the local customer service center of Emerson for technical support. (Parallel system) In the event of a fault in a unit, the unit will be automatically excluded from the system. If the system is still capable of providing the required load, the remaining units will continue to supply the load with no interruption.

  • Page 17: Ups Power Supply Switch Configuration

    Chapter 1 Overview Overload If the inverter is overloaded or the inverter current remains outside the specifications (refer to Table 11-6) longer than the specified time, the load will be automatically transferred to the bypass without power interruption. If both the overload and the current are reduced to a level within the specified range, then the load will be transferred back to the inverter.
  • Page 18 Chapter 1 Overview This mode supports two configurations: rectifier and bypass adopt two-route mains input, rectifier and bypass adopt one route input, but this mode does not support maintenance mode. Figure 1-3 describes the block diagram of the UPS in split bypass configuration (that is, the bypass adopts independent mains input).
