The power supply can also be used on two-phases of a three-phase-system.
Such a phase to phase connection is allowed as long as the supplying voltage

25.12. Use in a tightly Sealed Enclosure
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher
than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing item is inside the box.
Enclosure: Rittal Typ IP66 Box PK 9522 100, plastic, 254x180x165mm
Load: 24V, 32A; (=80%) load is placed outside the box.
Input: 230Vac
Temperature inside enclosure: 61.6°C (in the middle of the right side of the power supply with a distance of 2cm)
Temperature outside enclosure: 23.3°C
Temperature rise:
