Functional description

The PDU is a power distribution unit for use in IT racks. There are four design variants, with the following
distinguishing features:
– PDU metered: Energy measurement at the infeed per phase, i.e. output requirement of an entire
IT rack; no switching function; with display and network interface.
– PDU switched: Energy measurement at the infeed per phase, i.e. output requirement of an entire
IT rack; with switching function per individual output slot, display and network interface.
– PDU managed: Energy measurement and switching function per individual output slot; with display
and network interface.
– Slave PDU managed: Energy measurement and switching function per individual output slot (analo-
gous to PDU managed); but without display and network interface, with CAN bus for connecting to
CMC III Processing Unit (7030.000/.010 from software version 3.13) or PDU metered/switched/man-
