Illustration

The following diagram shows an NCU 730.3 PN with its interfaces and control and display
elements (fault displays and status indicators). Please ensure that the structure of the NCUs
is virtually identical. There are only a few discrepancies, as follows:
● NCU 710.3 PN and NCU 710.3B PN have 4 instead of 6 DRIVE-CliQ interfaces.
● NCU 710.3 PN and all .3B versions do not have any cooling ribs and therefore a different
NCU 7x0.3 PN, NCU 7x0.3B PN
