ECOMMENDATIONS FOR

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.

LEARANCES
The minimum clearance recommendations are defined in chapter 2.
Normally, the following installation clearance are recommended: 40mm on top, 20mm on the bottom, 5mm on the
left and right sides when the device is loaded permanently with more than 50% of the rated power. Increase this
clearance to 15mm in case the adjacent device is a heat source (e.g. another power supply).
The clearance between the power supplies and the redundancy module can be reduced to zero under the following
conditions:

1+1 redundancy application with maximum
40A output current.
-
The power supplies are from the PULS
DIMENSION series.
-
The redundancy module is placed between
the two power supplies or at least on one
side of the power supply.
-
The output voltage is set to the same level
on both power supplies.
