overcurrent-protected output for each DC power supply. Each output overcurrent-protected
device in the PDU must be suitable for interrupting fault current available from the DC
power source and must be rated no more than 40A.
The PDU output must have a shut-off switch or a circuit breaker to disconnect power for
each power supply. To completely remove power from the power supply, disconnect power
at the PDU. The end product may have multiple power supplies. To remove all power from
the product, disconnect the power for each power supply.
