PERATION ON
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
+10%
.
Ensure that the wire, which is connected to the N-terminal, is appropriately fused.
The maximum allowed voltage between a Phase and the PE must be below 300Vac.

IGHTLY
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 items are inside the box
The temperature sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1cm.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
