  • Page 18: Ups Power Supply Switch Configuration

    For single module system, 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, contact the local Vertiv technical support. For 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.
