PDU leakage current
WARNING Due to the number of components that can be installed on one
Power Distribution Unit (PDU), there may be a risk of high
leakage current (>3.5mA). Reliable ground circuit continuity is
vital for safe operation of such components. To reduce the risk of
electric shock, connect each component to a grounded outlet
only. Never operate any component with its ground pin
disconnected from the socket of a grounded outlet.
