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.

(at PSU)
The synch_start pin is connected to the
overcurrent signal of the PSU1-3. In the
case of an overcurrent shutdown, this
signal goes high.

Sync_start_A , Active high
The signals of several racks can be
connected together in such a way that all
supplies will be inhibited until the last
supply has recovered from its
overcurrent condition.
Referenced to Logic_GND
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).
