Vertiv Liebert EXS Installer/User Manual page 24

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. We recommend that you verify the sensitivity of each differential device of
the upstream input power distribution and downstream power distribution (to load).
Battery
The UPS includes an overcurrent-protection device for the internal battery.
UPS Output
The UPS includes output overcurrent protection in all modes of operation. If the customer-provided
output-distribution panel is not within sight of the UPS, the distribution panel must include a main
breaker.
