10.5.2.4 Multiple supplies
If currents higher than 1.2 A must flow out of an I/O row, a multiple supply is required.
If two or more supplies together deliver current to an I/O row other than their own (be it
local or remote), these supplies must themselves be placed in different I/O rows.
They must be connected by a short cable via the screw terminals.
