Procedure for Designing the NX Unit Power Supply System

The total power consumption from the NX Unit power supply must not exceed the NX Unit power sup-
ply 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 CPU Unit.
2
If the total power consumption from the NX Unit power supply exceeds the NX Unit power sup-
ply capacity of the CPU 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.
