5-2 Designing the NX Unit Power Supply
System
This section describes how to design the NX Unit power supply to the Profinet IO Device Terminal.
The total power consumption from the NX Unit power supply must not exceed the NX Unit power supply
capacity of the Unit that supplies the NX Unit power.
Use the following procedure to design the NX Unit power supply.
1
Calculate the total power consumption from the NX Unit power supply that is required by the NX
Units that are connected to the PROFINET Coupler Unit.
2
If the total power consumption from the NX Unit power supply exceeds the NX Unit power sup-
ply capacity of the PROFINET Coupler Unit, add an Additional NX Unit Power Supply Unit to the
right of an NX Unit before the capacity is exceeded.
3
Calculate the total power consumption from the NX Unit power supply that is required by the NX
Units that are connected after the Additional NX Unit Power Supply Unit.
If the total power consumption of those NX Units exceeds the NX Unit power supply capacity of
the Additional NX Unit Power Supply Unit, add another Additional NX Unit Power Supply Unit to
the right of an NX Unit before the capacity is exceeded.
4
Repeat step 3 until the design conditions for the NX Unit power supply are met.
