Installation Instructions
Installation of the converters must strictly follow the national
safety regulations in compliance with the enclosure, mounting,
creepage, clearance, casualty, markings, and segregation
requirements of the end-use application.
Connection to the system shall be made via a printed circuit
board with hole diameters of 1.5 mm for the pins.
The converters should be connected to a secondary circuit.
Do not open the converter.
Ensure that a converter failure (e.g., by an internal short-
circuit) does not result in a hazardous condition.
Input Fuse
To prevent excessive current flowing through the input supply
line in case of a short-circuit in the converter, an external fuse
should be installed in the non-earthed input line. We
recommend a fast acting fuse specified in table 3.
Standards and Approvals
All converters are safety-approved to IEC/EN 60950 -1 and
UL/CSA 60950-1 2
nd
Ed.
The converters have been evaluated for:
• Building-in
• Basic insulation input to output, based on their maximum
input voltage
• Pollution degree 2 (not option Z)
• Connecting the input to a secondary circuit, which is
subject to a maximum transient rating of 1500 V.
The converters are subject to manufacturing surveillance in
accordance with the above mentioned standards.

Railway Applications
To comply with Railway standards, all components are coated
with a protective lacquer (except for option Z).
Protection Degree
The protection degree is IP 30 (not for option Z).

Footprint. The holes in the PCB should have a diameter of
1.5 mm.
In order to avoid possible damage, any penetration of cleaning
fluids should be prevented, since the converters are not
hermetically sealed.
However, open-frame models (option Z) leave the factory
unlacquered; they may be lacquered by the customer, for
instance together with the mother board. Cleaning liquids are
not permitted – except washing at room temperature with
isopropyl alcohol and de-inonized/destilled water (1 : 1) .
Note:
Cleaning liquids may damage the adhesive joints of the
ferrite cores.
