Multiple Scan 720: Power Cable

The Multiple Scan 720 User Guide, page 3, illustrates and describes a shrouded pass-thru power cable for use with the monitor. However this monitor arrived with a standard cpu-wall power cable. Which one is correct?
The Multiple Scan 720 ships with a cpu-wall power cable, part number 590-0380. This is the cable that should be illustrated and described in the user guide, but is not.

Shrouded pass-thru power cables, used to connect the monitor power to the cpu power pass-thru port are available from most Apple Authorized resellers and service providers, part number 590-0370. This cable does not come with the monitor.
