5.2 Configuring Parallel System Operation
5.2.1 General
The NX uses intelligent and reliable decentralized technology to achieve parallel operation of two or
more modules of the same rating.
The 1+N system is used to:
• Increase the reliability of the system to ensure adequate power supply to the critical load con-
nected.
• Increase serviceability and allow the execution of maintenance operations and reparations with-
out affecting the ordinary operating conditions of the system (depending on the redundancy level).
