Thermal Considerations
Connection in Parallel
If a converter is operated, the relationship between the am-
bient temperature TA and the case temperature TC depends
heavily on the conditions of operation and integration into a
system. The thermal conditions are influenced by input volt-
age, output current, airflow, temperature of surrounding
components and surfaces and the properties of the printed
circuit board. The specified maximum ambient temperature
TA max is therefore only an indicative value and under practi-
cal operating conditions, the ambient temperature TA may
be higher or lower than this value.
Connecting the outputs of two or more converters in paral-
lel is not recommended due to uneven power distribution
among the outputs.
Protection Scheme
The IMR series is continuously short circuit protected by
means of input power limitation. The unit will not be dam-
aged if started up into a short circuit. After removal of the
short circuit, it will resume normal operation.
The IMR series is also no-load proof, meaning that the
regulation is still effective with no load and the output volt-
age does not rise. However, due to component tolerances,
oscillation could occur and ripple and noise can be outside
of specified values. If the converter is used in senitive elec-
tronic circuits with no-load conditions, it is recommended to
pre-load the outputs with at least 20% of the specified nomi-
nal load.
Caution: The case temperature TC measured at the
Measuring point of case temperature TC (see: Mechani-
cal Data) may under no circumstances exceed the speci-
fied maximum value. The installer must ensure that un-
der all operating conditions TC remains within the limits
stated in the table: Temperature specifications.
Connection in Series
The outputs of one or more units can be connected in se-
ries. No suppressor diodes are required. Power-One how-
ever recommends to protect each individual output with a
Zener diode or preferably a suppressor diode, to avoid re-
verse polarity that may occur if the output voltages do not
rise simultaneously.

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.
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 F3.15A for
12 IMR 6 types, F1.6A for 24 IMR 6, F0.8A for 40 IMR 6 and
48 IMR 6 types.
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.
Cleaning Agents
In order to avoid possible damage, any penetration of
cleaning fluids is to be prevented, since the power supplies
are not hermetically sealed.
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous condition. See also: Safety
of operator accessible output circuit.
Protection Degree
Standards and approvals
The protection degree of the DC-DC converters is IP 40.
The units have been evaluated for:
• Building in
Table 7: Electric strength test voltages, clearance and
creepage distances
• Operational insulation input to output
• 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 1500 V.

If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to IEC/EN 60950

However, it is the sole responsibility of the installer to as-
sure the compliance with the relevant and applicable safety
regulations. More information is given in: Technical Infor-
mation: Safety.
The following table shows some possible installation con-

1 The front end output voltage should match the specified input voltage range of the DC-DC converter.
2 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950.
3 The installer shall provide an approved fuse (type with the lowest rating suitable for the application) in a non-earthed input conductor
directly at the input of the DC-DC converter (see fig.: Schematic safety concept). For UL’s purpose, the fuse needs to be UL-listed.
See also Input Fuse.
4 Each suppressor diode should be dimensioned in such a way, that in the case of an insulation fault the diode is able to limit the output
voltage to SELV (<60 V) until the input fuse blows (see fig.: Schematic safety concept).
5 Has to be insulated from earth by double or reinforced insulation according to the relevant safety standard, based on the maximum
output voltage from the front end.
