• Using Unwired Unit Power Supply Terminals
In this example, the current consumption from each power supply is as follows:
Current consumption from Unit power supply: I_unit1 + I_unit2 ≤ Lowest rated current
Current consumption from I/O power supply: I_io1 + I_io2 ≥ Lowest rated current
*1
*1. This is the lowest rated current of all of the Units that supply I/O power and are connected to protective
devices. For example, if terminals with both a 10-A and 4-A capacities are connected, the value is 4 A.
