ECOMMENDATIONS FOR

EDUNDANCY
Recommendations for the configuration of redundant power systems:
•
Use separate input fuses for each power supply.
•
Use three-phase power supplies to gain functional safety if one phase fails.
•
When single-phase power supplies are utilized connect them to different phases or mains circuits if possible.
•
Set the power supply in “Parallel-Use” mode if this feature is available
•
It is desirable to set the output voltages of all power supplies to the same value.
