    The current sharing between nonisolated power supplies relies on equal voltages at the power supply input terminals. The M320 system power is divided into two load zones. One load zone consists of PEM0 and PEM2, and the other load zone consists of PEM1 and PEM3. For nonisolated power supplies, load sharing occurs only between the power supplies of each load zone (PEM0 and PEM2 or PEM1 and PEM3).
