    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 that case the automatic inverter switch at inverter side is closed.

  • Page 18: Ups Power Supply Switch Configuration

    In case of inverter failure and output fuse blowout, the load will automatically transfer to the bypass, and the output power supply will not be interrupted. In this situation, please contact the local customer service center of Vertiv for technical support.
