Synch Start-up Connection Between Shelves
The following connection between the shelves is required to achieve a parallel operation. The synch-start circuits
inside the shelves inhibit all power supplies until the last one has recovered from its overcurrent condition and then
synchronize the restart of the outputs.

NOTE: The Sync-Start pins can be wired together only if the power supplies are connected with a minimal voltage drop on power ground as
achieved on a backplane with massive copper bus bars. If there is a less ideal connection, it is recommended to use an opto-coupler for each
unit (IC1, D3, D2).
