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.
