    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).
