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
300V AC.

Use In a Tightly Sealed
Enclosure
When the power supply is installed in a tightly sealed enclosure, the
temperature inside the enclosure is 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 1 cm (0.39 in.).
The following measurement results can be used as a reference to estimate the
temperature rise inside the enclosure.
Prohibited Applications
The power supply does not support certain applications:
• Do not use the power supply in parallel to increase the output power.
• Do not use the power supply to charge batteries.
• Do not use the power supply with DC-input voltage.
