Installation Instructions
Installation 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.
The converter must 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
lines in case of a malfunction an external fuse should be
installed in a non-earthed input supply line; see table 4 .
Standards and Approvals
The converters are approved according to IEC 60950-1 and UL/
CSA 60950-1 2nd Edition. 110IMY models are fitted with a CE
mark.
The converters have been evaluated for:
• Building in
• Supplementary insulation input to output, based on their
maximum input voltage (IMX15, IMS15)
• Reinforced insulation input to output, based on their
maximum input voltage (IMY15 models)
• Pollution degree 2 environment (not option Z)
• Connecting the input to a secondary circuit subject to a
maximum transient rating of 1500 V (IMX15, IMS15)
• Connecting the input to a secondary circuit subject to a
maximum transient rating of 2500 V (IMY15)
The converters are subject to manufacturing surveillance in
accordance with the above mentioned UL standards and with
ISO9001:2008.
Railway Applications
To comply with railway standards, all components are coated
with a protective lacquer (except option Z).
Protection Degree and Cleaning Liquids
The protection degree of the converters is IP 40, except open-
frame models (option Z).
In order to avoid possible damage, any penetration of cleaning
fluids should be prevented, since the power supplies are not
hermetical 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. If necessary, the mother board must be
cleaned, before fitting the open-frame converter.
Note: Cleaning liquids may damage the adhesive joints of the
ferrite cores.
Isolation
The electric strength test is performed in the factory as routine
test in accordance with EN 50514 and IEC/EN 60950. The
Company will not honor any warranty claims resulting from
incorrectly executed electric strength field tests.
