Electrical hazard – risk of power disruption
Due to power supply safety features, some AC voltage will be coupled to the
redundant power terminals (between the positive/live and chassis/ground terminals,
and between the neutral and chassis/ground terminals). While the maximum
amount of current transfer is below the safety threshold, it may be enough to trip
some external Ground Fault Circuit Interrupter (GFCI) breakers. Before connecting
power, review the installation and make sure this condition can be supported.
