Safety and Installation Instructions
Installation Instruction
Installation of the DC-DC converters must strictly follow the
national safety regulations in compliance with the enclo-
sure, 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 according to:
Mechanical Data.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.
Do not open the module.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also:

Input Fuse
To prevent excessive current flowing through the input sup-
ply line in case of a short-circuit across the converter input
an external fuse should be installed in a non earthed input
supply line. We recommend a fast acting fuse F2A for
5 IMX 4, F1A for 20 IMX 4, F0.5A for 40 IMX 4 and F0.315A
for 70 IMX 4 types.
Safety of operator accessible output circuits
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to IEC/EN 60950
related safety standards
The insulation concept table below shows some possible
installation configurations, compliance with which causes
the output circuit of the DC-DC converter to be an SELV cir-
cuit according to IEC/EN 60950 up to a configured output
voltage (sum of nominal voltages if in series or +/– configu-
ration) of 46 V.
However, it is the sole responsibility of the installer to en-
sure the compliance with the relevant and applicable safety
regulations. More information is given in:
Technical Infor-
mation: Safety.
Standards and approvals
All DC-DC converters are UL recognized according to UL
1950, UL recognized for Canada to CAN/CSA C22.2 No.
950-95 and LGA approved to IEC/EN 60950 standards.
The units have been evaluated for:
Building in
Supplementary insulation input to output, based on their
maximum input voltage
The use in a pollution degree 2 environment
Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1000 V for 5 IMX 4,
1500 V for 20 IMX 4 and 40 IMX 4, 2000 V for 70 IMX 4
types.
The DC-DC converters are subject to manufacturing sur-
veillance in accordance with the above mentioned UL,
CSA, EN and ISO 9001 standards.
