    The residual current circuit breaker (RCCB) must be sensitive to the DC unidirectional pulse (Level A) in the power distribution network, but insensitive to the transient current pulse, see Figure 2.2 below . Figure 2.2 RCCB Symbols 2 Installation Proprietary and Confidential ©2024 Vertiv Group Corp.
  • Page 18: Equipment Handling And Unpacking

    When using the earth RCD in a split-bypass system, the RCD should be installed at the upstream input power distribution end to prevent false alarms. The earth leakage current fed by the RFI filter in the UPS ranges from 3.5 mA to 100 mA. Vertiv recommends that you verify the sensitivity of each differential device of the upstream input power distribution and downstream power distribution (to load).
