23.6. OPERATION ON TWO PHASES
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.
23.7. USE IN A TIGHTLY SEALED ENCLOSURE
When the device 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 device.
In the following test setup, the device is placed in the middle of the box, no other heat producing items are inside the
box. The load is placed outside 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.
