IMX4 Series Data Sheet  
4 Watt DC-DC Converters  
Standards and Approvals  
Safety and Installation Instructions  
The converters are approved according to UL/CSA 60950-1 and  
IEC/EN 60950-1 2nd Edition.  
Installation Instruction  
Installation of the dc-dc 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.  
The converters have been evaluated for:  
• Building-in  
• Basic insulation input to output, based on their maximum  
input voltage  
Connection to the system shall be made via a printed circuit  
board; see Mechanical Data.  
• Pollution degree 2 environment  
• Connecting the input to a secondary circuit, which is subject  
to a maximum transient rating of 1500 V for 20IMX4 and  
40IMX4, and 2000 V for 70IMX4 models.  
The converters should be connected to a secondary circuit.  
Do not open the converter.  
The converters are subject to manufacturing surveillance in  
accordance with the above mentioned standards and with ISO  
9001:2008.  
Ensure that a converter failure does not result in a hazardous  
condition.  
To prevent excessive current flowing through the input lines in  
case of a short-circuit, an external fuse specified in table 6  
should be installed in the non-earthed input supply line.  
Railway Applications  
To comply with railway standards, all components are coated  
with a protective lacquer (except option Z).  
Pin Allocation  
10013b  
Protection Degree and Cleaning Liquids  
The protection degree of the converters (except opt. Z) is IP 40  
for models with Revision BA (or later). Older models have IP 30.

In order to avoid possible damage, any penetration of cleaning  
fluids should be prevented, since the power supplies are not  
hermetically sealed.

Foot print  
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 agents 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.

The electric strength test is performed in the factory as a 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.
