Wiring the Unit Power Supply
This section describes the wiring of the Unit power supply to the Unit power supply terminals on the
CPU Unit.
Connect the DC power supply to the Unit power supply terminals on the left side of the input terminal
block.
The + terminals and - terminals are internally connected to each other.
You can use the unwired terminals for through-wiring to an Additional NX Unit Power Supply Unit or to
the Unit power supply terminals on another NX1P2 CPU Unit.
When you supply the Unit power through the unwired terminals, be careful not to exceed 4 A, the cur-
rent capacity of power supply terminals.
