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
is below 240V

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 denes 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: 38.3K
