    Vertiv™ Liebert® APM Plus User Manual 2.2.2 Bypass Through the intelligent control of the ‘Static Switch’ module (as shown in Figure 2.1 on the previous page) containing the controllable electronic switch, the loads can be supplied by the inverter or the bypass. In normal situation, the loads are supplied by the inverter, in this case the automatic inverter switch at inverter side is closed.

  • Page 20: Ups Power Supply Switch Configuration

    In case of inverter failure, output fuse blowout, and bypass STS failure the load will automatically transfer to the bypass. In this situation, please contact the local customer service center of Vertiv Tech Co., Ltd for technical support. (Parallel System) In the event of a fault in a UPS module, it will automatically exit from the parallel system. If the system is still capable of providing the required load, the remaining modules will continue to supply the load with no interruption.
